Winchester MP4 CO2 rifle
Daisy’s Winchester MP4 is a realistic and fun-to-shoot military replica pellet rifle. The gun is shown here with added Leapers UTG 3-9×32 Bug Buster scope and AR-15 rubber recoil pad.

This report covers:

• Scope notes
• More pellet testing
• I know there’s something going on
• The Winchester trio
• RWS Diabolo Basic pellets
• RWS Hobby pellets
• H&N Match Pistol pellets
• The magic bullet? Beeman hollowpoint coated pellets
• Retesting the best
• Conclusion
• Other military pellet rifles to consider

In Part 2, I found five pellets that would group 7/8 of an inch (0.875 inches) or better with the Winchester MP4 CO2 rifle at 10 yards (Crosman Destroyer pellets, Crosman Destroyer EX pellets (sold only in discount stores), Crosman Premier Hollowpoint pellets, H&N Finale Match Pistol pellets, and Air Arms Falcon pellets). This was about as good as I expected based on my research before purchasing this gun. However, I’d hoped that I could do better, and most of the reader comments on this blog expressed even greater concern with the mediocre accuracy of this gun than with the ammo feed problem. I’m pleased to report some slightly better news.

Scope notes
But first, I made a minor modification to my scope setup. I mentioned the trouble two other shooters had sighting through the Leapers UTG 3-9X32 Bug Buster scope I mounted on this rifle. I had positioned the scope for my own eye relief, and eye placement proved to be a lot more critical for this compact scope than it is with my full-sized Leapers UTG 4-16X40.

However, at least part of the difficulty they experienced may have been due to a fairly low Picatinny rail on this rifle. When the included factory scope rings loosened after 300 shots, I decided to try a different style mount and also decided to go with high-profile rings. I was surprised at how much easier it became to sight through the scope — especially since I would have thought I wasn’t having any real difficulty before. For most shooters, I believe high-profile scope rings will be the way to go on this rifle. With my new scope setup, I was ready for some final accuracy testing.

Winchester MP4 CO2 rifle High Scope Mount
High-profile scope rings makes it a little bit easier to sight through the UTG 3-9X32 Bug Buster scope on the MP4′s low Picatinny rail.

One minor note here. On Picatinny rails there’s usually a little play in the scope mounts within the individual recoil grooves, and I usually slide both my mounts forward until they contact the forward stops and then snug them up right there. This is the direction the laws of inertia demand that the scope and mounts will want to go in relation to a rifle recoiling backwards beneath them (especially pneumatic or CO2 guns with simpler recoil than a springer). If the mounts are already braced against the forward stops, then there’s less chance for them to slip. However, on the Winchester MP4, I believe the semi-auto bolt re-cocking generates some recoil in the opposite direction – this may have actually loosened my initial scope installation. This time, I braced both scope mounts against the rear stops, and they seem to be holding fast, so far. I don’t have the equipment to verify this recoil theory, but it’s something to try if you run into a similar problem.

[Editor's note: While Picatinny rails and Weaver rails both have cross slots to stop the rings from moving, Weaver slots are 3.5mm wide and Picatinny slots are 5mm wide. That's the reason for the extra slop when Weaver rings are installed on Picatinny bases. And, for airguns, the pins should touch the rear of the slots.]

More pellet testing
I continued testing with seven new pellets, shooting 10-shot, 10-yard groups outdoors from a benchrest. I shot three groups with each pellet, and reported the best of three below. With my original accuracy testing, all the pellets I tried grouped about 1 inch, give or take a little. However, this time, the groups were generally tighter — even with pellets I’d previously tested. I believe this barrel may have a break-in period — roughly 500 shots by my estimation — and is now smoothed out a little. For this test, I used digital calipers to provide more exact group measurements — though, even with my sharp eyesight and a science background, you can take that third decimal place with a grain of salt!

I know there’s something going on
There definitely seems to be something going on between the number of pellets in the rotary cylinder and accuracy. I’d already mentioned that the last two shots of my 10-shot groups, involving a magazine swap, often opened up the final grouping. Remember that the ammo mag has 8-round cylinders, so finishing off a 10-round group required switching to a cylinder with only the two final pellets loaded. I could blame the repositioning of the rifle between magazine swaps, except that this is not a problem I’ve had with rifles that require pumping or cocking and get repositioned with every shot. This time, I kept specific track of when my final two shots opened up a group, with the results illustrated below.

Winchester MP4 CO2 rifle Last 2 Shots
You can see how the final two shots (circled) opened up each of these 10-shot groups. Left-to-right are Crosman Premier Super Match pellets, RWS Hobby pellets, and Air Arms Falcon pellets.

This batch of testing also confirmed something else I thought I’d noticed before — groups often started off very small, then opened up as I emptied the magazine. Obviously, shooting more pellets will continue to open up a grouping. What I’m saying is that shot 10 was much more likely to miss the bullseye than shot 1, rather than having a similar probability of hitting or missing it. With this semiauto, I could lock myself into a rested shooting position and do nothing but breathe and squeeze the trigger for 8 shots. Barely moving, my aim and hold were rock solid. However, I almost felt like a spectator at times as I watched pellet strikes begin to roam wider and wider around my point of aim. I believe this is the same phenomenon I observed with my final two shots of each group. My best guess is that adjacent pellets in the magazine cylinder help reduce some CO2 blow-by, or that a full magazine cylinder does not shift or flex during firing as much as an empty one.

On the left, the first three shots with Beeman coated hollowpoint pellets go into 0.261 inches, center-to-center. Keeping my fingers crossed at this point! But the fourth shot (circled) opens this group up a bit more to 0.323 inches. Six increasingly scattered shots later, the final group on the right is now even broader at 0.682 inches (that fourth shot is circled on this target as a reference point). This pattern was observed repeatedly. This was not the best example I saw. It was just the one I interrupted to photograph.

The Winchester trio
Since this is a Winchester air rifle, I felt duty-bound to put the Winchester pellets through their paces. While they were the poorest performers of all the new pellets, their best groups were all still 1 inch or less: Winchester hollowpoint pellets (0.826 inches, center-to-center), Winchester pointed pellets (0.859 inches), and Winchester round nose pellets (1.000 inches exactly). As mentioned, the Winchester hollowpoints extended past the front of the rotary cylinder when fully seated and had to be pushed back in slightly before shooting. However, they caused no jams or other firing problems.

The Winchester hollowpoints extend past the front edge of the rotary cylinder when fully seated.

RWS Diabolo Basic pellets
The RWS Diabolo Basic pellets yielded the next largest group of the bunch, with its best-of-three at 0.791 inches. This pellet also produced the largest group that I observed during this second round of testing — 1.324 inches.

Winchester MP4 CO2 rifle RWS Diabolo Basic
Ten RWS Diabolo Basic pellets grouped inside 0.791 inches –close to the best that was seen in the first round of accuracy tests.

RWS Hobby pellets
The RWS Hobby’s smallest group measured 0.644 inches. This was the best group I’d seen from this gun so far. It’s approaching the as-of-yet elusive half-inch mark, but not quite there.

Winchester MP4 CO2 rifle RWS Hobby
Ten RWS Hobby pellets in 0.644 inches — easily my best group up to this point.

H&N Match Pistol pellets
I’d tested the more expensive H&N Finale Match Pistol pellets last time, but then I read about H&N Match Pistol pellets actually outperforming the Finales in another gun I own. That’s why I ended up with a tin of these to try. At 0.716 inches, they grouped slightly better than the Finales (even with retesting, as you’ll see in a minute) in this gun, too.

Winchester MP4 CO2 rifle H&N Match Pistol
The H&N Match Pistol pellet, at 0.716 inches for 10, outperformed both previous and repeated testing of the H&N Finale Match Pistol pellets.

The magic bullet? Beeman hollowpoint coated pellets
Okay, I’ll concede right up front that half-inch groups at 10 meters aren’t all that magical in today’s airgunning world. However, with a review quoting Daisy Customer Service as stating that MP4 owners should expect 1-1/2 inch groups at 10 meters, and with no measured groups under 1 inch reported by anybody, I was pleased to finally break the half-inch barrier with Beeman hollowpoint coated pellets.

I did not have high hopes for what is literally the cheapest pellet I tested. However, a single Pyramyd Air review mentioned it performed well (thank you, DaveTee!); and, for under five dollars a tin, it went into the shopping cart. I shot this pellet last, and it surprised me. My three test groups yielded 0.682 inches, 0.386 inches and 0.442 inches. At the eleventh hour, I’d finally found a pellet that could shoot under half an inch. While one thing that became clear during accuracy testing is that my rifle does not perform the same with specific pellets as other’s MP4s, the Beeman hollowpoint coated is definitely one to try for anyone who owns an MP4, especially at this price point.

Winchester MP4 CO2 rifle Beeman HP Coated
Thar she blows — these two groups shot with Beeman hollowpoint coated pellets clock in at under half an inch, at 0.386 and 0.442 inches, left to right. (Yes, the pellets are black.) Summer sun heating the barrel on one side caused the point-of-impact shift that can be seen here.

Retesting the best
To wrap up Part 4, I wanted to retest the best-performing pellets from before, which had all grouped 7/8 of an inch (0.875 inches) or less. I was pretty sure one or two could do better, and it seemed that my rifle was starting to produce tighter groups than it had straight out of the box. These were my results: Air Arms Falcon pellets (0.622 inches, beating out the RWS Hobby pellet for second place), Crosman Destroyer EX pellets (0.630 inches, taking third place and booting the RWS Hobby pellet to fourth), Crosman Destroyer pellet (0.742 inches, just a hair better than before), and H&N Finale Match Pistol pellets (0.963 inches, actually a little wider than first time’s 0.875 inches and still getting beat out by the H&N Match Pistol pellet). A small surprise were the Crosman Premier Super Match pellets (0.707 inches) and Crosman Competition Wadcutter pellets (0.720 inches), which I used for initial sighting-in of my new scope mount setup. Both bettered their original 1-inch groups by more than a quarter inch. Again, I believe this barrel is now broken in after 500 shots or so, contributing to these tighter groups and providing better overall accuracy than we saw in the first tests.

Winchester MP4 CO2 rifle Air Arms Falcon 2
The best of the retests was the Air Arms Falcon pellet, second-best to the Beeman hollowpoint coated pellet, but grouping almost twice as broad at 0.622 inches.

Conclusion
Below is a summary of best groups one inch or better from all accuracy testing:

Winchester MP4 group sizes

While discovering the Beeman hollowpoint coated doubles my effective shooting range to around 20 yards for a 1-inch target, it’s a shame that this gun seems to be a “one-shot wonder” that shoots best with only one specific pellet. From the list above, there’s no single pellet type that this gun seems to prefer as direction for additional testing, so I hope that blog readers will be kind enough to comment if they find other pellets that group under half an inch in the Winchester MP4.

Other military pellet rifles to consider
For the conclusion to my evaluation of the Winchester MP4, I’d like to mention some of the other military replica pellet rifles prospective buyers might consider if they decide that the MP4 is not for them. (BB-only rifles and machine guns are not included here.)

I’ve already mentioned the MP4′s historically older sibling, the Winchester M14. A replica of its namesake, this rifle is also a dual-CO2 canister BB and pellet semi-auto. It uses the same ammo mag and offers the same velocity as the MP4. However, it has no scope rail and many don’t like the fact that the stock is composite instead of wood.

The unquestioned dominator of the military pellet rifle arena remains the Crosman M4-177. This M4 replica is a reliable single-shot BB and pellet pneumatic and bears the coveted Gaylord “Tom’s Picks” seal in the Pyramyd Air catalog. It’s available in a variety of tan or black color and accessory combinations. The new Crosman USMC MOS 0311 Rifleman (an exclusive Crosman variation of the M4-177) appears to be another variant of this very popular replica. This is the gun I had in mind when I mentioned that more accurate rifles than the Winchester MP4 are available for half the price.

The Crosman MK-177 is a replica of the Magpul Masada (now being produced as the FN SCAR). This composite-stock pneumatic offers higher velocity and similar accuracy to the M4-177 (also beating the Winchester MP4 in the latter department, and for half the price). This rifle is a BB and pellet single-shot. B.B. Pelletier recently used the MK-177 to test the Leapers Accushot Scout Scope. While many disparage the bolt placement on the left side of the receiver, I own — and love — one of these rifles and never minded it (this is a replica — check on which side the bolt is actually located on the Magpul Masada). The MK-177 is available in tan or black and has two kit variations.

The Crosman Crosman MTR77NP is an M16 replica that is a single-shot Nitro Piston gas springer. This pellet rifle offers the highest velocity of any of these military replicas but requires heavy cocking effort due to the short barrel. It’s available in only black but comes in open-sight or scoped versions.

If you actually own an AR/M4 firearm, the Crosman MAR177 AR-15 Upper PCP conversion kit replaces the firearm upper with a .177-caliber competition precharged pneumatic unit. Designed specifically for 10-meter competition, velocity is a very nominal 600 fps. This is the most expensive option for a military pellet rifle (and a significant detour from the standalone guns listed here), but it seems like an ideal way to expand where and when you can shoot your military long gun.

The Beretta CX-4 Storm is an 88-gram CO2-powered replica of the tactical firearm of the same name. This semiauto’s claim to fame is the 30-pellet belt magazine, capable of ripping through a tin of pellets in no time. Open-sight and red-dot versions are available, though a scope can be mounted on the Picatinny rail.

The Gamo MP9 copies the B&T MP-9 9mm SMG and is unique among the CO2-powered BB submachine guns in handling pellets as well. Interestingly, this gun is listed as using the same ammunition magazine as the Winchester MP4 and M14, making it a 16-shot semi-auto (with the magazine flip). I included this odd-gun-out because it has a (collapsible) stock and scopeable Picatinny/Weaver rail.

Winchester MP4 CO2 rifle Flambeau Tactical Case
The Winchester MP4 is a fun military replica that, despite some issues and limitations, will keep you looking like a well-armed commando whenever you feel the need to reconnoiter the backyard.

The options for new military replica pellet rifles are very limited at the moment. I hope that this blog has sufficiently informed readers about the Winchester MP4 to make an educated choice if buying one – or to achieve the best performance from their rifle if they already own one. I also hope that manufacturers will look to success stories like the Crosman M4-177 as well as the burgeoning airsoft market and bring some novel products to this mostly unexplored marketplace.

Editor’s final comment: HiveSeeker has done a super job in testing, researching and documenting his work on the Winchester MP4. I think his report will stand as the best article written about the airgun for a long time.

Winchester MP4 CO2 rifle

Daisy’s Winchester MP4 is a realistic and fun-to-shoot military replica pellet rifle.

This is the third installment in my evaluation of the Winchester MP4 CO2 rifle. The short version of Parts 1 and Part 2 is that this gun might be of interest to someone looking for a realistic AR15-style semiauto pellet rifle — as long as they can accept 1-inch, 10-yard groups and an intermittent ammo feed problem. I was determined to find out what was causing the ammo feed issue in order to minimize or eliminate it and was also certain the gun could shoot tighter groups with more testing. In Part 3 and also in Part 4, I make progress on both fronts.

This report covers:

• Catch-up
• The ammo feed problem
• Testing the ammunition magazine
• It’s the CO2 clip!
• Eliminating minor misfires

Catch-up
Before we continue, I want to add a couple comments that should have been included previously. First, in addition to the authentic realism of this replica gun, at 5.8 lbs., it hefts like a firearm. Most of the other military-style pellet rifles out there are lighter, and a number of reviewers mention that the realistic weight of the Winchester MP4 adds to its appeal. I agree.

Second (and B.B. was kind enough not to chide me for this), I failed to mention that despite the manual’s statement that no additional lubrication is needed for this gun once it leaves the factory, go ahead and put a drop of Crosman Pellgunoil on the tip of each CO2 cylinder when you install it. That will help keep all those seals healthy and happy for years to come.

The ammo feed problem
I hadn’t experienced the MP4′s ammo feed problems to nearly the extent of some other shooters, but I was determined to figure out the possible causes and eliminate or minimize them. I suspected that the problem might be related to either the ammunition magazine (which has an 8-shot rotary cylinder on each end where the pellets or BBs are loaded), or the CO2 clip (which holds the two CO2 cartridges). I already had a number of spare magazines and ordered six additional CO2 clips directly from Daisy Customer Service for testing.

Two ammunition magazines on the left. They have 8-shot rotary cylinders on each end that hold the pellets or BBs. On the right are two CO2 clips that hold the CO2 cartridges. The ammo mag slides into it. Keep all these terms straight for the discussion below! That little plastic CO2 piercing key fits neatly into the slot at the bottom of the CO2 clip cover.

Testing the ammunition magazine
While I initially suspected the ammunition magazines were the source of inaccuracy, one curious fact is that these are the same ones used by the Winchester M14 and they apparently work flawlessly in that gun. It got 14 out of 15 five-star reviews at Pyramyd Air. We’ll come back to the ammunition magazine in a moment, but suffice to say that I ended up testing 9 different ammo mags in each of 7 different CO2 clips and found no difference in their performance. None of the ammo mags were malfunctioning.

Winchester MP4 CO2 rifle testing
Ammunition magazines and some CO2 clips ready for testing in the Winchester MP4. A few pellets, too — that’s coming in Part 4.

It’s the CO2 clip!
The CO2 clips proved to be another story. When they arrived from Daisy, they were all in excellent condition, but it was clear that two of them had been used. When I inquired, I was told that not enough new CO2 clips were available, so two units were pulled from returned MP4s. This is not encouraging, but they were much cheaper than expected, so I had no complaints. I marked all 7 of my CO2 clips and got ready to test the new arrivals. Clip 1 is the already-tested original that came with my rifle.

The first shot using clip 2 (the first of the 2 used clips) was a major flyer, zinging well off my point of aim. Not an auspicious start. Second shot, no pellet — just air (which I’ve been calling a misfire and one of the few ammo feed issues I’ve actually experienced up to this point). The third shot was my very first jam with this gun. The ammunition magazine would not eject from the CO2 clip, and I had to eject the CO2 clip itself to get the ammo mag loose.

I was especially careful to reseat the CO2 clip solidly for my next try. Fourth shot was another flyer but not quite as bad as the first. Fifth shot was another jam. This one was worse than the first, with the trigger jammed solid and the ammo mag again not ejecting. This time when I ejected the CO2 clip, the ammo mag actually stayed lodged inside the receiver!

It was suddenly clear what had happened — a pellet was jammed halfway between the ammo mag’s rotary cylinder and the barrel, locking the ammo mag in place. Fortunately, I had a plastic rod for clearing jams. Sure enough, I could feel the pellet slide back a little and then the ammo mag simply fell out of the gun.

When I examined the magazine, both the noses and skirts of several of the pellets showed visible deformation. This was the first time I’d really experienced the frustration of other MP4 buyers who had ended up returning their guns. I’d had enough — I was done testing clip 2! (Note that Daisy Customer Service replaced this clip with a brand new one at no charge.)

The ammo mag was jammed in the gun, separate from the CO2 clip!

Winchester MP4 CO2 rifle damaged pellets
This is what a bad CO2 clip does. This jam was so bad that the ammunition magazine remained lodged inside the receiver even after the CO2 clip was ejected. Note the damage to the two pellet skirts, especially the one on the right.

With no small amount of trepidation, I shot a full magazine using original clip 1, just to make sure my gun had not been damaged. Thankfully, everything was back to normal.

I was ready to test CO2 clip 3 — the other used one. Except for being a little tight in the receiver (something I’d also noted with my original clip), it performed flawlessly with all 9 ammunition magazines. I did have to push harder for the ammo mags to click into place, but that was all — and this actually smoothed out by the time I was finished testing. My experience was identical with the remaining brand-new CO2 clips 4 through 7. They varied in how tightly they fit into the receiver and how tightly ammunition magazines fit inside them, but they smoothed out with just a little use. And after hundreds of pellets, I had only a few misfires, which I subsequently decided were my own fault.

Here’s my important finding: The worst ammo feed problems are probably being caused by bad CO2 clips. Either the CO2 clip itself is not seating correctly within the receiver, or ammunition magazines are not seating correctly inside the CO2 clip. Either will cause the pellet not to line up with the barrel, resulting in a jam or misfire. This also explains why the identical ammunition magazine performs flawlessly in the Winchester M14 (where it locks directly into the receiver) but suddenly starts having problems in the MP4.

The obvious conclusion is that a replacement CO2 clip just might fix a misfiring MP4. If you order one directly from Daisy, try to make sure you’re getting a brand-new one, as these performed flawlessly – though I only had trouble with one of the two used clips. Note: To add to the nomenclature confusion, if you order this part from Daisy Customer Service, both they and the exploded parts diagram refer to the CO2 clip as the “Puncture Unit” (Part 79).

The Winchester MP4 exploded parts diagram. If you are ordering a replacement CO2 clip, it’s referred to as the “Puncture Unit” (Part 79).

We’ll take a minor detour as long as we have the MP4 parts diagram up. A number of reviews and blog comments describe the MP4 as a dressed-up Winchester M14. I initially thought otherwise, but the schematics prove me wrong. The barrel assembly and many other internal components appear identical. The CO2 clips share many parts as well. However, in the M14, the ammunition magazine slides freely through a hole in the CO2 clip and locks directly into the receiver. In the MP4, the ammo mag latches to the CO2 clip, which then latches into the receiver. As we’ve seen, having a middleman (the CO2 clip) between the ammo mag and the receiver is a potential problem. Besides the CO2 clip, the biggest differences between the M14 and the MP4 lie in the trigger mechanisms, receivers, and stocks and forearms.

T
he Winchester M14 does, indeed, share many parts with the MP4.

 

Winchester MP4 CO2 rifle M14 CO2 clip
These are Winchester M14 CO2 Clips. The ammunition magazine slides freely through a hole in the CO2 clip (circled) but does not click into it. Instead, the ammo mag locks directly into the receiver — no middleman here! An ammo mag is shown inserted into the hole in the clip on right. This CO2 clip can be misaligned with the M14’s receiver without affecting ammo mag alignment at all.

Back to the MP4. One Pyramyd Air review suggests that the ammo mag misalignment may be caused by CO2 pressure pushing the CO2 clip slightly out of position. This is certainly plausible and might also explain why this problem can worsen over time (as other reviews report) if increasing wear is occurring. If wear is occurring on the CO2 clip, a replacement CO2 clip could fix the problem. If wear is occurring inside the receiver — or should something actually be wrong with the receiver to begin with — then it’s time to contact the manufacturer or start picking out a new rifle.

I ended up content with the fact that one of my new CO2 clips was not working (again, Daisy Customer Service sent a free replacement). Otherwise, I would still be scratching my head about what could be causing the more severe ammo problems I’ve been reading about. The fortunate bottom line is that this provides a likely fix for people with MP4s that are misfiring or jamming. Order a replacement CO2 clip from Daisy or Winchester Customer Service and see if that doesn’t remedy the problem.

Eliminating minor misfires
Although I never experienced a major ammo problem or jam, except while testing CO2 clip 2, I was still having minor misfires (firing a blank or a skipped pellet left in the ammunition magazine when done shooting). This was occurring about once every one or two magazines (or once every 16 to 32 shots if you’re counting — roughly 5% of the time). I wanted to eliminate this if I could. When I contacted Daisy Customer Service to order the extra CO2 clips, I inquired about this. While the Daisy rep did not acknowledge a known ammo feed issue with the MP4, I not only received some suggestions over the phone, but a follow-up email with additional information, as well.

Winchester MP4 CO2 rifle skipped pellet
Except for testing CO2 clip 2, all of my own ammo feed problems were limited to infrequent misfires (blank shots) and an occasional skipped pellet that remained in a supposedly empty ammunition magazine.

Daisy cautions that you should use good-fitting (tight) pellets and make sure they’re seated all the way. This will prevent pellets from backing out of the magazine (more specifically the rotary cylinder), causing a jam. I’ve been using a Pellet Pen with Pellet Seater for loading, and the advice makes sense. However, none of the pellets I tested were loose, and most actually fit quite tightly. Ironically, the only pellet that caused a problem was Winchester’s own hollowpoint, which stuck out the front of the cylinder (even when fully seated) just enough to interfere with the cylinder’s rotation. I simply pushed the pellet noses back in slightly and didn’t experience any misfires during subsequent accuracy testing.

Despite how tightly most pellets fit, however, if I pulled an ammo mag that still had pellets in it I sometimes noticed that pellets I had seated all the way into the cylinder were loose and pushed back a little. On one occasion, I actually had a loosened pellet fall backwards right out of the magazine. I could not determine what might actually be pushing pellets backwards in their cylinder cavities, but my first guess is that CO2 bypass somewhere must be exerting pressure on the front of the pellets. The gun’s mild recoil (or possibly the bolt recocking action) might be another possibility. Whatever the cause, once this happens previously stopper-tight pellets will slide easily in the cylinder. As far as I could determine, though, pellet fit was not a problem in my gun. And it was not the problem for Pyramyd Air reviewers who tried a range of pellets with all kinds of persistent problems, either – that was probably the CO2 clip.

Winchester MP4 CO2 rifle loading pellets
I went to great lengths to load each pellet the same.

Winchester MP4 CO2 rifle rotary cylinder
Use a pellet seater to seat pellets fully into the rotary cylinder. A very tiny ridge (arrow) stops the pellet skirt within each individual cylinder chamber.

Daisy’s other – and I think more relevant – suggestion was to shoot slower, allowing 3-5 seconds between shots to let the CO2 cartridges recover. My first thought was that this takes away a lot of the fun of a semi-auto. This specific feature was one of the reasons I’d purchased the MP4 to begin with. Of course, the first thing my wife did as soon as she got her hands on my new gun was see how fast she could make me work the reset cord on our knockdown target. Sure enough, she had a skipped pellet in the magazine following her quick-fire volley. That’s not quite fun.

My second thought, in the form of a tiny bell ringing in the back of my mind, was that during my chronograph tests when I was waiting a full minute between shots, I didn’t have a single misfire for almost 150 rounds. I thought this was an anomaly, but it wasn’t!

With this advice in hand, I continued my testing, making a point to take time to breathe several times between shots. Lo and behold, I went through nearly 600 pellets with only 4 misfires, and I believe I actually caused these. Two of the misfires were from shooting fast during some other testing, and the other two are discussed below. Slowing down my shooting has essentially eliminated all my misfires—though I’m not having quite as much fun with the semi-auto MP4 as I was before.

Now, as to those final two misfires. After ejecting a supposedly empty ammunition magazine and discovering a skipped pellet still present, I remembered that on one shot I’d partially depressed the trigger, run out of “breath” before I was ready to shoot and released the trigger for another try. When I later removed the CO2 clip, I inverted the gun and squinted down into the receiver. As I squeezed the trigger, sure enough, I saw the catch that indexes the rotary cylinder move. So, squeezing the trigger indexes the ammo mag cylinder, and I’d inadvertently rotated a pellet out of queue, causing a skipped pellet. This revelation occurred early in my latest round of testing, and I continued shooting with steady, deliberate trigger pulls after that (and tried to make sure I didn’t run out of “breath” again). This also means that you should fully release the trigger between shots, though this was not a problem for me as far as I could tell. More deliberate trigger work, along with slower pacing between shots, has resulted in no more misfires so far.

Winchester MP4 CO2 rifle cylinder indexing
This rectangular catch (shown by the large arrow) just under the breech indexes the rotary cylinder on the ammunition magazine when the trigger is pulled. The inset photo and small arrow show the ratchet teeth on the rotary cylinder that the catch engages. A false start on a trigger pull can rotate the cylinder without actually firing, causing a pellet to be skipped in the firing sequence.

In summary, misaligned CO2 clips appear to be causing the most severe ammo feed problems in the Winchester MP4, and a replacement CO2 clip should get a malfunctioning MP4 working correctly. Tight-fitting pellets, slower shooting and more deliberate trigger pulls can eliminate minor misfires; but these require additional time and concentration and take some of the fun out of shooting this semi-auto. While I really like the Winchester MP4 and continue to enjoy shooting it, I’m having to jump through hoops to make it work properly, which is something prospective owners need to consider.

In Part 4, I’ll complete my accuracy testing (and finally break the half-inch barrier) and wrap up my evaluation.

Winchester MP4 CO2 rifle

Winchester MP4 is a realistic and fun-to-shoot military replica pellet rifle.

This report covers:

• Shots per fill
• Heavy trigger
• Best results
• The normal grouping
• Bug Buster
• Summary
• The Dallas Field Target Club inaugural shoot
• How the blog changed my life

Shots per fill
While testing pellet accuracy, I shot at 6 bullseye targets (60 shots), swapping CO2 cartridges after each set, and did not notice any decline in performance at 10 yards. I also did a lot of enjoyable spinner silhouette shooting and started noting an increase in misses only as I approached the 80-shot mark (you go through pellets fast with this semiauto!). In conclusion, shooters can expect at least 60 accurate shots before swapping CO2 cylinders, depending on temperature.

It doesn’t matter how good the Winchester MP4 CO2 rifle looks with that bipod or red dot scope on it while you’re reconnoitering the backyard. How well does it shoot? A gun is only fun if you can hit what you’re aiming it at, and the Winchester MP4 does reasonably well in the accuracy department.

Heavy trigger
My rifle does not appear to be suffering from the reported loose barrel problem (which can ostensibly be remedied by removing the 6 screws holding the Picatinny forearm and hand-tightening the barrel). However, the trigger-pull on this rifle is a conspicuously heavy 7.6 lbs. according to my hand scale. My wife and brother-in-law, who is former military (both ends of the spectrum, and both experienced shooters), singled this out as a major complaint. This is no youth rifle. I agree that accuracy would be better without having to exert so much pressure to get a pellet off. However, after some limited travel, the trigger — heavy as it is — breaks clean and crisp.

I shot outdoors at 10 yards from a benchrest using the aforementioned Bug Buster scope and a Leapers Golden Image 30mm red dot sight. All pellets tested grouped right around 1″ — give or take a little. Results were slightly better using the BugBuster. This rifle is not a tackdriver but is certainly a solid performer as long as you keep the range at 10 yards.

Best results
The following pellets gave the smallest 10-shot groups. At least one out of three measures 7/8″:
Crosman Destroyer
Crosman Destroyer EX (the slightly different version sold only in discount stores)
Crosman Premier Hollowpoint
H&N Finale Match Pistol
Air Arms Falcon

Winchester MP4 CO2 rifle Destroyer EX
Ten Crosman Destroyer EX pellets (a slightly different version of the Destroyer pellet sold at discount stores) went into 7/8″ at 10 yards.

Winchester MP4 CO2 rifle Finale Pistol
Ten H&N Finale Match Pistol pellets made this 7/8″ group at 10 yards.

Winchester MP4 CO2 rifle Falcon
These Air Arms Falcons also grouped in 7/8″ at 10 yards.

These three pellets gave at least one 10-shot group out of three as small as one inch between centers:
Crosman Competition Wadcutter
Crosman Premier Super Match
Gamo Tomahawk

The worst pellet tested was the JSB Match Diabolo Light Weight. They gave a best group that measured 1-1/8″ between centers.

The normal grouping
Most groups were erratic and inconsistent, with more pellet scattering than clustering. Nevertheless, the largest groups I got were still a reasonable 1-1/2″ (for the Crosman Destroyer EX and Gamo Tomahawk). Since each group was 10 shots, I filled one drum of the magazine completely (8 pellets) and then put only 2 pellets in the drum on the other side of the mag.

One interesting and frustrating observation was that my final 2 shots, after flipping the magazine around, almost always opened up the group, in some cases by a full half-inch or so. At least part of the time, though, this gun is capable of significantly tighter groups than I’m reporting here.

Winchester MP4 CO2 rifle pellet scattering
On the left is the only really tight group I got — 7/8″ for the Crosman Destroyer EX. Nearly every other group looked a lot more like the Crosman Premier Hollowpoint group on the right, with hardly 2 pellets in the same hole anywhere.

Bug Buster
I mentioned that I shot this gun with a Leapers UTG 3-9×32 Bug Buster scope. When I first started sighting in at 10 yards, my initial POI was a very low 5″ under the bullseye. I had to do a lot of clicking to get the POI near the bullseye; and by the time I was finished, I noticed a fair amount of blurring in the bottom quarter of the scope’s field of view. I suspect I’m approaching the limit of adjustment on this sight. The amount of blurring worsens at higher magnifications. I own another Leapers UTG 4-16×40 scope that I just love, but field of view and eye relief on the compact Bug Buster are not nearly as forgiving or comfortable. Both my wife and brother-in-law (again, each an experienced shooter) complained about how difficult it is to sight through this scope. Although the Bug Buster has performed reliably and adds to the military look of this gun, I’m going to try a 40mm or larger compact scope on it at a later date.

Winchester MP4 CO2 rifle Bug Buster
The Leapers UTG 3-9×32 Bug Buster was much better to look at than to look through. The scope showcased the drawbacks of a small-objective compact.

A couple minor notes before wrapping up: Although Pyramyd Air rates this rifle a 4 out of 5 for loudness, I didn’t find it to be especially noisy outdoors. On my screened porch, the report was definitely loud, but that depends on how the sound is bouncing off the walls. Shooting noise from inside a bedroom was only average, which is how I would rate this gun for sound.

Also, the manual states that you should store this gun uncocked. Every time you fire, the bolt is re-engaged by CO2 pressure for the next shot. After you’ve finished shooting and have removed the CO2 clip, remember to point the rifle in a safe direction and squeeze the trigger one last time before casing it.

Summary
In conclusion, the Winchester MP4 is an authentic- looking and handling military replica with some known issues but enough accuracy to make it quite enjoyable for casual shooting. For plinking around the yard while looking like a commando, this rifle fills the bill — and does so nicely.

The Dallas Field Target Club inaugural shoot
Bob Dye submitted the following report and photos of the first Dallas Field Target Club shoot.

Twenty-six shooters appeared on a beautiful June 14 day for the event, some traveling from as far as Oklahoma and Louisiana.

Dallas FT Club meeting
The first Dallas Field Target Club match was well-attended.

Everyone had fun with friendly competition in all the usual AAFTA competition classes. Among them were 6-7 new shooters. Some chose to participate in one of the regular AAFTA classes, while four others participated in a Fun Rifle category, where basically anything goes concerning shooting style and equipment choices.

Great scoring latitude was offered, scoring one point for simply hitting the animal faceplate and two for a knockdown. This appeared to be a great way to let the novice shooters have fun scoring points plinking lead against steel, along with the extra satisfaction when the target falls over. It also served as a fun change of pace among the experienced shooters.

Dallas FT Club shooter
Shooters enjoyed the relaxed pace of the day.

While the facilities have lanes long enough to create a challenging Troyer difficulty of 36 or more, this first, 50-shot match was built on 9 lanes to a 23 Troyer, again to put some smiles on faces the first time out. [Editor's note: Brad Troyer devised a way to rate the difficulty of a field target course based on the size of the kill zones; the distances at which they're placed; and the difficulty of the shot based on placement, light and shooting position.]

Accordingly, two of the seasoned veterans rose to the challenge to ace the course. David Alsup shot a perfect 100/100 in Open PCP. And, while I told him I thought he was a shoo-in to do this, David asked to keep his score card, indicating it was a special day for him, too. Great shooting, David!

Likewise, perennial Hunter Class leader Ron Robinson also shot 100/100 with his brand new TM1000 rifle. I haven’t seen such a big grin on Ron’s face is some time. Or at least since last weekend in Pulaski. Ask him how he likes his new rig and be prepared for 5 minutes of superlatives. Excellent match with a new rifle, Ron!

Altogether, 17 of the 26 competed in one of the two Hunter Classes, including two in Hunter Piston. Four people posted scores in Open PCP — rather unusual in these parts.

The mostly sunny weather cooperated for a mid-June day, with a high of only 85 degrees F during the match, which made the humidity bearable. The turnout was superlative for this first ever club match.

Thanks to members Kevin Enzian, Jeff Latimer and Jerry Cupples for helping me set up the course the afternoon before. I couldn’t have done it by myself.

Next match is in August. Stay tuned. Visit the Dallas Field Target Club website.

How the blog changed my life
I initially published this section on the May 30, 2014, blog. I’m going to repeat it at least once a week during June and July so it doesn’t get lost or forgotten.

From the comments many of you make, I believe the blog may have positively impacted your lives. I invite you to send me an email telling me about that impact.

Were you a firearms shooter who accidentally discovered airguns through this blog? If so, tell me how this blog has helped your understanding of airguns.

Winchester MP4 CO2 rifle: Part 1

by Tom Gaylord, a.k.a. B.B. Pelletier

Today’s report is a guest blog from a new reader, HiveSeeker. He wants to tell us about a pellet rifle he thinks highly of. This is a complete report with the description, velocities and test targets, so I am breaking it into two sections.

If you’d like to write a guest post for this blog, please email me.

Over to you, HiveSeeker.

This report covers:

• Ammo feed
• Velocity

Winchester MP4 CO2 rifle

Winchester MP4 is a realistic and fun-to-shoot military replica pellet rifle.

Description
Considering the astonishing array of military rifle lookalikes in the airsoft world, it’s a shame that there are so few choices among airguns. But those who would enjoy shooting an accurate reproduction pellet rifle might consider the Winchester MP4 CO2 rifle. Styled closely after the AR15, this .177 airgun features a full-metal receiver, quad Picatinny rail forearm, working selector switch (safety), realistic magazine catch and adjustable stock — lots of authentic moving parts that are only fixed plastic on a number of the other military replicas. The forward bolt assist is only ornamental, but the charging handle (hereafter called the bolt) is fully functional. This also happens to be one of the few semiauto replica pellet rifles available. My ex-military brother-in-law experienced a fair amount of nostalgia shooting this rifle.

Winchester MP4 CO2 rifle The selector switch, magazine catch (on right side of gun) and adjustable stock are fully functional. Note the position of the fully inserted CO2 clip, which looks like the ammo magazine.

Sights
The first thing you’ll want to do after unboxing the MP4 is remove the cheap plastic open sights — among the unfriendliest I’ve ever squinted through. They’re not individually adjustable, and the manual doesn’t include one word about them. Just know that you can raise or lower the aiming point by moving the front sight closer or farther in relation to the rear sight; they apparently cannot be adjusted for windage. [Editor's note: The manual and Winchester's website state the rear sight is adjustable, so we asked the manufacturer about it. They say it's not adjustable and plan to remove that statement from their website and from future reprints of the manual.]

A red dot sight works well (and looks tacti-cool) on this gun, though I primarily used a Leapers UTG 3-9×32 Bug Buster scope, which also looks very good. The all-metal receiver provides a very solid platform for mounting optics compared to the plastic receivers of some other contenders in the military pellet rifle arena. Despite being a low-recoil CO2 gun, the bolt recocking mechanism apparently generates some vibration. As a shooter who admittedly tends to over-tighten everything, I was stunned to find my scope mounts loose after about 300 shots. Keep an eye on this.

Winchester MP4 CO2 rifle You’ll want to replace the plastic open sights right away.

The MP4 looks ready for combat with either a red dot sight or compact scope. That quad Picatinny rail is just begging for more accessories!

Loading
This gun requires two 12-gram CO2 cartridges. You can spend all day trying to “remove the cover from the base of the CO2 clip by inserting a finger into the ammunition magazine hole and pulling the cover off” (as the manual suggests). There’s no hidden release, and the instructions of course mean the larger CO2 clip hole to the right (go ahead and laugh, manual-spurners).

My CO2 clip fits very tightly in the receiver; and the first time I tried to shoot this gun, it took me a couple trigger pulls to realize the clip was not seated all the way. Look closely at the photos to see how far the clip must slide in. Clip insertion and removal are slightly smoother now but initially required a fair amount of pressure.

Winchester MP4 CO2 rifle Remove the CO2 clip cover by inserting a finger into the larger hole on the right (not the smaller one on the left) and pulling up. It’s easy if you’re not following the wrong instructions! The plastic key above the clip cover is used for installing the CO2 cartridges.

Ammo feed
Exercise more care in gently inserting the ammunition magazine, however, as the thin plastic of the round rotary drums is easily cracked. A magazine holds 16 pellets or BBs, though this is a bit deceptive. There are only 8 rounds in each end, and you have to perform a magazine flip to shoot all 16 rounds. I suggest buying at least a couple extra magazines. The buttplate I found to be uncomfortably hard, but a rubber AR-15 add-on fit perfectly, as will most other AR accessories, except anything for the nonstandard pistol grip. My next add-on will be a bipod, which should fit perfectly on the forearm.

Winchester MP4 CO2 rifle Insert the ammunition magazine gently. The thin plastic of the 2 rotary drums is easily cracked.

If you’ve read any reviews of the Winchester MP4, then you already know that there’s a major ammo feed issue with this gun. Mine is no exception, but so far the problem has been occasional enough to live with — only about 1 pellet out of every 1 to 2 magazines (averaging around 5%) is failing to fire. This is despite carefully using a pellet seat; a tiny ridge inside each individual drum cavity stops the skirt, allowing consistent loading of each pellet. Other owners, however, have experienced a much worse problem, so I’m keeping my gun as is.

Velocity
Let’s look at some chronograph data. My 10-for-$10 test printout from Pyramyd Air with 7.1-grain Beeman Lasers showed a velocity range of 480-538 fps, with an average of 500 fps even. Waaay lower than the listed 700 fps (which I initially figured was just for BBs), as a number of reviewers have pointed out. For my own tests, I shot 10-shot strings at sea level, waiting one minute between shots, using a Shooting Chrony Beta Master. With 4-grain Crosman SSPs I got a range of 683-710 fps and an average of 694 fps in the better of two tests (air temperature was 88˚F).

Interestingly, the other test string averaged a lower 686 fps but contained my single-shot velocity record of 722 fps. So, the Winchester MP4’s velocity stated on the box is correct, and this gun indeed shoots just as fast as Daisy claims — and with pellets, no less. I did not test with BBs, although this gun is designed to shoot them, wishing to save my barrel (and its accuracy) for pellets only.

Testing with a more typical pellet, the 7.9-grain Crosman Premier Super Match, provided expectedly lower velocities: 487-562 fps with an average of 511 fps (at 84˚F). This was much closer to the 10-for-$10 results. Below are my average shot string velocities.

Shot string….Avg velocity
1-10…………………..511
11-20………………..496
21-30………………..483
31-40………….…….470
41-50…………….….449
51-60………………..444
61-70…………….….438
71-80………………..421

Summary
HiveSeeker continues his test with accuracy results in the next report. I’ll run that next week.

Hatsan 250XT TAC-BOSS: Part 1

by Tom Gaylord, a.k.a. B.B. Pelletier

Before I start, here’s a word on the project I’m doing on how this blog has affected people’s lives. The emails are coming in, and they’re big and full! I think we’re going to get a lot out of this.

A reminder to those who don’t know what this is. I’m asking readers to email me the story of how the blog has impacted them. I’ll maintain complete anonymity for everyone unless you tell me that you want me to use your name or handle. And your email addresses only go to me — no list is being kept.

To join this project, click this link to find the special email address at the bottom of the May 30 blog report. I look forward to hearing from you.

Hatsan 250XT TAC-BOSS
Hatsan’s 250XT TAC-BOSS bears a close resemblance to the Ruger Mark III Hunter.

This report covers:

• BB caliber
• Piercing problems
• Description of the gun
• Action
• A lot of BB guns!

The airguns at this year’s SHOT Show were exciting for a number of reasons. I mention them as they come up in these reviews, and today we’ll begin looking at a BB pistol that I was very surprised to see. Hatsan’s 250XT TAC-BOSS bears a strong resemblance to a Ruger Mark III Hunter .22 pistol. Normally, lookalike airguns are copies of either military or otherwise iconic firearms. The Ruger Mark III is certainly a popular handgun, but it’s not really in either category. Yet, here’s a BB pistol that copies it so closely that it even has the quirky Ruger disassembly lever in the back of the pistol grip.

The 250, as I’ll call it for the rest of this report, is powered by a single 12-gram CO2 cartridge that’s contained in the magazine with the BBs. That mag slips into the pistol grip, just like a firearm mag. The gun is made in Taiwan and has an airsoft heritage. That seems to be the popular thing today, an airsoft manufacturer converts one of their guns from 6mm plastic BBs to 4.3mm steel BBs.

Hatsan 250XT TAC-BOSS magazine
The magazine is held in by a spring at the bottom, just like the Ruger mag. It holds both the BBs and the CO2 cartridge. The piercing screw is hidden from view in the magazine floorplate.

The magazine holds 17 BBs in a stack. To load the gun, you pull down on the magazine follower and drop the BBs in through the top portal one at a time.

BB caliber
And, by the way — I know that nearly all airgun makers refer to steel BBs as 4.5mm and .177 caliber these days, but they’re not! BBs measure 0.171-0.173-inches in diameter, which works out to just over 4.3mm. This is important when owners try to do things that won’t work because their guns are mislabeled. That’s why I always refer to steel BBs as either BB caliber or I tell you the nominal measurements.

Piercing problems
This airgun doesn’t have blowback but I wanted to make sure, so I installed a CO2 cartridge. Naturally, I used a drop of Crosman Pellgunoil on the tip. When the cartridge is pierced, the gas usually stops flowing instantly. It didn’t this time. A soft hiss went on for 15 seconds as I tightened the cartridge more and more, using the large Allen screw in the magazine base. That’s very unusual, so I exhausted the gas and tried a second cartridge from a different manufacturer, also with Pellgunoil on the tip. Since I had to release all the gas in the first cartridge, the magazine was allowed to sit for 10 minutes to return to room temperature before the second trial.

The second time, the gun sealed immediately, just as it should. Since I used a different cartridge for this test, I conducted a third test using the first brand of cartridge, just to see if it was a cartridge problem. It wasn’t. The third cartridge also sealed immediately. This is a lesson in how important it is to always use a drop of Pellgunoil on the tip of each cartridge, because this pistol really needed it!

Incidentally, I really like how the piercing screw is hidden in the base of the magazine. I know BB pistol shooters make a big deal over being able to see the piercing mechanism, and on this gun you can’t.

The gun
The gun is finished entirely black. The grip frame and grips are plastic, as well as both sights. The remainder of the parts are metal, including the fluted barrel jacket. The barrel is 6.75 inches long and smoothbored. The shape of the triggerguard doesn’t match the Ruger Mark II triggerguard. This one is scalloped for the finger(s) of a second hand. That’s probably an improvement because two-handed pistol shooting is very popular today.

The gun weighs 29 oz., and the grip is very comfortable. Both sights are fixed, and the front sight has a green fiberoptic tube. That probably makes sense on a BB gun as it is a point-type airgun. You don’t need precision for a BB pistol.

Hatsan 250XT TAC-BOSS front sight
The front sight has a green fiberoptic tube. The rear has none.

The bolt doesn’t move, though the Ruger-like flanges at the rear will make you at least give it a try. I think a blowback version of this pistol would be so cool because that bolt would come back just like the bolt on a firearm.

Hatsan 250XT TAC-BOSS safety
The safety is on the left side of the frame and can be operated by the thumb of a right-handed shooter. The rear sight is fixed. The bolt tabs look like they might move, but they don’t.

The safety is in the same place as the safety on the Ruger firearm, and it works the same way. It’s easy to apply, and a right-handed shooter can both apply it and take it off with their thumb. Once applied, it blocks the trigger.

Action
This pistol is double-action only. That said, the trigger-pull is light and smooth. There’s no stacking (sharp increase in the pull effort) near the end of the trigger travel. There’s a pause at the end of the travel, however, and a skilled handgunner will be able to pull to this point, then squeeze off the shot.

A lot of BB guns!
Before anyone mentions it, I have been testing a lot of BB guns this year. And there are a lot more to come. This seems to be the year of the BB pistol, and Edith and I have selected the ones most people are talking about; or in the case of today’s pistol, the ones they should be talking about.

Legends Makarov Ultra: Part 3

by Tom Gaylord, a.k.a. B.B. Pelletier

Part 1
Part 2

Umarex Legends Makarov Ultra BB pistol
Umarex Legends Makarov Ultra is very realistic!

This report covers:

• Loading
• Winchester Target Cube
• Rested position
• Accuracy
• Overall evaluation

Today is accuracy day for the Legends Makarov Ultra BB pistol and the big question is: How does it hold up against its non-recoiling brother that we all know is very accurate? I think you’re going to be pleased with the results.

Load up
I installed a fresh CO2 cartridge, which — thanks to yesterday’s report on CO2 – reminded me to put a drop of Crosman Pellgunoil on the tip of the cartridge before piercing. As before, the piercing was nearly instantaneous with no loss of gas. I looked at the face seal with a jeweler’s loupe and saw that it’s a thick (relatively) clear synthetic that looks like it will do its job for a long time to come.

Next, I loaded some BBs into the front of the magazine. Here’s a tip for this. Lock down the mag follower at the bottom of its slot and elevate the bottom of the mag. This way, the BBs will easily fall into the enlarged hole in the front of the magazine. If one overshoots the mark, it remains in a trough and can be rolled back to the hole very easily.

Umarex Legends Makarov Ultra BB pistol loading magazine
Elevate the bottom of the Makarov magazine, and the BBs will roll right in.

Winchester Target Cube
Once again, the Winchester Airgun Target Cube was pressed into service for a target holder and backstop. I taped the targets to the cube that now has thick cardboard on both sides. No more styrofoam comes out because of the cardboard; and the targets tear better, even when the BBs are shot at lower velocities.

The Target Cube keeps the BBs from bouncing back. That keeps the shooting area cleaner; and since I shoot BBs in my bedroom, that’s a good thing. If you shoot a lot of BBs in the house, I recommend the Target Cube.

Rested position
I then sat on a chair at 5 meters from the target and put a large pillow on my lap. When doubled over, the pillow allowed me to rest my arms so I could achieve a very steady 2-hand hold. It’s the gun we want to test — not the shooter.

The sights on the Makarov are very fine, but also sharp. I had no problem getting the same sight picture, shot after shot.

First group
The first target I shot was a 50-foot smallbore bull. Those are just slightly larger than 10-meter air rifle bulls. I had no idea where the pistol was shooting, nor how accurate it might be; but at 16 feet, I felt this target was large enough to keep all the shots on paper. I used a 6 o’clock hold, like I always do with handgun sights like these.

The shots landed about 3/4-inch below the point of aim. While the first 3 shots seemed to scatter, the next 7 stayed inside them, resulting in a fine-looking 10-shot group. In measures 0.916 inches between centers and looks even better. The bulk of the shots landed inside a half inch!

Umarex Legends Makarov Ultra BB pistol target 1
Ten BBs in 0.916 inches, with 7 of them well under a half inch! The 3 shots on the right were the first 3 shots. This gun can shoot!

Second group
The second target looks even better.  I called that shot that went to the left because of the very hard trigger pull we’ve already discussed. Actually, the trigger isn’t that hard for a double-action pull (which it isn’t), but for target shooting it’s way more than you want. This time, 10 shots went into 1.189 inches, with 9 of them in 0.727 inches.

Umarex Legends Makarov Ultra BB pistol target 2
Ten BBs in 1.189 inches, with 9 in 0.727 inches. That shot on the left is a called pull.

I was really impressed with the way this pistol wants to lay them in the same hole at 5 meters. That trigger pull, though, takes discipline to overcome. The tendency is to try to overpower it, which will result in shots thrown wide to the left in my case.

Third group
I decided to try a larger aim point for the third group, so I substituted a 10-meter pistol target instead. The bull is twice the size of the others, and I wondered what it might do. Oddly, it pulled my shots closer together, though I did get a very vertical shot string. This time, 10 shots went into 1.334 inches, with 9 in 0.683 inches. Look at this group, and you’ll see the pedigree of the non-recoiling Makarov showing through.

Umarex Legends Makarov Ultra BB pistol target 3
Ten BBs in 1.189 inches, with 9 in 0.727 inches.

Results
Yes, I think this Makarov is just as accurate as its non-recoiling brother. What separates them is the stiffer trigger on this one. It makes you really hold tight, and any distraction will cause you to throw a shot.

Overall evaluation
I like the Makarov Ultra BB pistol. In fact, I think I’m going to buy this one for my growing collection. This is what inexpensive BB pistols should be.

Legends Makarov Ultra: Part 2

by Tom Gaylord, a.k.a. B.B. Pelletier

Part 1

Umarex Legends Makarov Ultra BB pistol
Legends Makarov Ultra is very realistic!

This report covers:

• Single-action trigger.
• Charging.
• Loading.
• Velocity.
• Blowback.
• Slide remains back when magazine is empty.
• Shot count.

Let’s look at the velocity of the Legends Makarov Ultra BB pistol. Because the gun has blowback, I’ll also report how that works.

Umarex is currently making a huge marketing push on their lookalike airguns and the undisputed leader in airguns that look like firearms. The Makarov Ultra is one of their latest and greatest new products.

Trigger
A firearm Makarov has a trigger that’s both single-action and double-action. Single-action means the hammer must be cocked for the gun to fire, and the blowback action of the slide accomplishes this. But for the first shot, you must manually cock the hammer, because, unlike the firearm Mak, the trigger on this pistol will not cock the hammer on its own. The Makarov Ultra trigger is not double-action.

The trigger-pull, however, is quite odd. A single-action trigger is traditionally light and crisp. The Makarov Ultra trigger, however, pulls through a long arc, and the pull force increases as the trigger nears the end of its arc. It feels like a double-action trigger, even though by strict definition it’s single-action because the hammer must be cocked separately.

The trigger is not objectionable, nor is it too heavy. It just doesn’t feel like a conventional single-action trigger.

Charging the pistol
The pistol is charged by a conventional 12-gram CO2 cartridge. The cartridge fits into the magazine that drops from the Makarov’s pistol grip. Because the Makarov has a magazine release located behind the rear of the magazine floorplate, it’s not convenient to release from the pistol and requires the use of 2 hands to do the job.

Umarex Legends Makarov Ultra BB pistol magazine
Like many BB pistols, the Makarov Ultra’s magazine houses the BBs, CO2 cartridge and the gun’s valve.

Once the magazine is out of the pistol, the CO2 cartridge installs easily and is tightened in place by the tension screw on the bottom of the mag. The piercing went so fast there wasn’t even a telltale hiss of gas that escaped the cartridge. Naturally, I put a drop of Crosman Pellgunoil on the tip of the cartridge before installing it.

Loading
The stick BB magazine loads very easily. I put the base of the mag up on a small ledge to elevate it and pulled the follower down to its locking point. A funnel-shaped hole on the magazine is where the BBs are fed in. If the magazine is sloped forward just slightly, up to 16 BBs drop in and roll forward with ease. This is perhaps the fastest-loading stick magazine I’ve yet encountered.

With the bottom (floorplate) of the magazine elevated slightly, the BBs drop easily through the widened hole and roll out of the way.

Velocity
Umarex rates the Ultra pistol at 350 f.p.s., and I found the rating to be slightly conservative. I started shooting BBs with the first shot out of the pistol, and the first few shots with a 12-gram cartridge are almost always above the expected average. Let me show you 10 shots from the first string of 16 BBs that were fired. Several BBs failed to trigger the chronograph’s skyscreens, but all 10 shots came from the first string of 16 BBs fired from the gun.

Shot Velocity
1       370
2       372
3       364
4       360
5       344
6       350
7       349
8       344
9       346
10     342

I allowed at least 10 seconds between each shot, except for between shots 4 and 5. There were several BBs that failed to trip the skyscreens between those 2 shots and I didn’t allow as much recovery time. The average for these 10 shots is 354 f.p.s., with a variation of 28 f.p.s.

The next 10 shots are much more telling. This time I allowed at least 15 seconds between each shot, and when they failed to trigger the skyscreens, I still allowed the time.

Shot Velocity
1       383
2       352
3       374
4       364
5       361
6       358
7       360
8       355
9       356
10     353

This time, the average velocity was 362 f.p.s. and the spread was 31 f.p.s. That means the average went up with the second 16 shots. Notice how fast that first shot is? The gun had laid dormant for at least 10 minutes after the first string. All of this is on the same CO2 cartridge.

Blowback
The Makarov Ultra is a lightweight BB pistol, so the blowback is pretty snappy. It feels very much like shooting a firearm.

Slide remains back
After the last BB has been fired, the slide remains back, making it obvious the gun is out of ammunition. This is the same thing the Makarov firearm does.

The slide stays back when the magazine is out of BBs.

Shot count
Besides velocity and how well the blowback works, another important performance parameter is the number of shots you can expect to get from a CO2 cartridge. For the first 2 magazines, I was conserving gas unrealistically, just to get an idea about the velocity potential. So, I shot the entire third magazine the way a shooter might — pulling the trigger as fast as I could. That took the total count up to 48 shots. On the fourth magazine, I slowed down to one shot every 10 seconds and got an average velocity of 320 f.p.s. The numbers declined steadily as these shots were fired. So the gun was running out of gas. But that’s still a shot count of 64 on one cartridge.

Blowback was still strong through magazine 4. On the fifth magazine, though, the gun started to sound weaker almost immediately. And on shot 9, the slide failed to cock the hammer for the first time. Therefore I think it is safe to say the Makarov Ultra will give you 4 good magazines on one CO2 cartridge.

Accuracy testing will come next. I hope the Makarov Ultra is an accurate BB pistol because its manual cousin — the gun that doesn’t have blowback — is legendary!
