This report covers:
• Learning to work on airsoft guns
• Components of airsoft guns
• Parts commonality — the airsoft way
• Various upgrades to components
• Need for a systematic approach to upgrades
This report is the beginning of the second installment of a promise I made to some of our readers. They wanted to know how to upgrade and work on airsoft guns, and I said I’d show them. The last report was written half a year ago, but I’ll get the next one out a bit faster. In fact, I’ve already written it!
How do you learn?
If you think there’s a lack of information about working on pellet guns and BB guns — you should experience airsoft! Not only is there very little information, much of it suffers from poor translation from various Asian languages to English. If you persevere, though, there are places to find this information — and, today, you can add this blog to the list.
I had to learn the hard way — on my own by doing it. I think that’s a rite of passage among airsofters. Most of this work is not that difficult once you know what you’re doing, but there are so few places that tell you how to begin. I was fortunate to have an airsoft store owner advise me when I first learned, so I’ll pass along a lot of what he taught me.
Airsoft parts groups
The first thing to learn is that there are several components in any airsoft gun that can be upgraded. They are:
• Powerplant (usually sold as a kit but sometimes can be purchased separately)
• Batteries and motors — applies only to automatic electronic guns (AEGs)
• Accessory components (these are not what you’d think)
A universal truth
There are many airsoft guns and many airsoft manufacturers, but there is a very high degree of commonality throughout the industry. If we were talking about cars, it would be the equivalent of Ford making all the engines for all cars, regardless of what name was on the car. There would be no such thing as a Corvette engine. It would be a Ford engine with the Corvette name on the outside.
A small assortment of airsoft parts. These parts are available from online sources to upgrade most guns.
While there are dozens of different models of sniper rifles, there might be only 2 or possibly 3 really different designs. In some cases, there’s just 1. I’m not just talking about sniper rifles now — I’m talking about all the different families of airsoft guns. You look at M4s, for instance, and you’ll find 15 different names on the outside. That doesn’t mean anything. There might just be 2 different M4s that everybody makes into their own proprietary rifle. So, in the world of airsoft, there’s no such thing as an Armalite M4. The Armalite M4 is the same as the Olympic Arms M4 and the Colt M4, etc. Get it?
Unlike most airgun manufacturers, airsoft manufacturers freely publish their illustrated parts breakdowns and schematics like this. They’re protected from American liability laws by their U.S. distributors.
The first thing you have to do, therefore, is discover which parts will fit on your specific model. Don’t expect to find a universal Rosetta Stone with all this information! It’s not the same as going to the auto parts store and looking in that thick book of parts applications. What you have to do is converse with the manufacturer/distributor or go on the airsoft forums and ask questions. Let me give you a specific example.
Sniper rifle barrels are nothing but smooth tubes. If you paid $99 for your sniper “rifle,” the tube that came on it is probably quite a bit larger than most 6mm airsoft ammunition. Why? Because the sniper rifle manufacturer knows you are a cheap person — having spent only $99 to buy a sniper rifle, when you could easily have spent 3 times that amount. Because you are cheap, you will probably also buy and use cheap airsoft ammo, and that’s the stuff that is oversized and not uniform. It will work much better in an oversized barrel — where the term “work” means continue to come out the end of the muzzle when the trigger’s pulled.
This is a typical airsoft barrel.
But…if you actually want to hit a man-sized target at 50 meters with the first shot, a cheap sniper rifle is not the gun to use. For that, you need a rifle with a tighter barrel (which is still a smooth tube), and you need to find and continue to use only the one correct round in your gun. In other words, you need to become what many will call an airsoft “snob.”
As surprising as it may sound, you can buy a tighter barrel for your cheap sniper rifle — often from the company that made the rifle! You see, they didn’t actually make that barrel. They bought it from 1 or 2 barrel makers who supply barrels to all of the airsoft community (the Ford engine in the Corvette). And there are different grades of tightness among barrels! This is where the airsoft forums come in handy. Someone will tell you that to upgrade your $99 Whango Tacticool M40, you need a Sho-Lin barrel that’s only 0.20mm larger than 6mm. It will work on your rifle, but you have to shoot 0.24-gram Black Mambas through it because everything else will jam.
If you can follow this advice to the letter, you can make a nice sniper rifle. And, when you’re done with the barrel and all the rest of the modifications, the price of your upgraded rifle will have about tripled! Small world, no? But, if you’re the guy who constantly wants to substitute Owl Sweat for Kangaroo Juice, because there’s a sale on it at a store near you, don’t even think of modding an airsoft gun! All you’ll do is spend money on a pile of parts that will never work together.
The Asians call this the Mech Box or Meca Box. It took me several months to figure that out the first time, and it’s important to know if you want to find them on the internet.
The $125 M4 AEG often comes with plastic gears. If you plan on shooting it only on holidays and at family gatherings, buy one and be done with it. By the way, if there’s a brand name like Colt on the outside of the gun, plan on spending 3 times as much and still getting plastic gears (sometimes)!
If you want to go into battle and have the gun continue to function for several days and thousands of shots, think about metal gears. But it doesn’t end there. There are also special shim spacers to keep the gear wheels aligned under a load, and there are special reinforced metal gearboxes that don’t wear like the cheaper gearboxes do. At the top of the list are the gearboxes that are built with pins (gear axels) that have been align-bored by a custom builder. A gearbox upgrade kit in a blister pack can cost you $68, or you can spend $400 with a custom builder who makes the gearbox specifically for your gun.
So, you see the Super Zombie Black Ops (a name I just made up) M4 AEG selling online for $99msays it comes with steel gears on the outside of the box! Big deal! That’s the airsoft equivalent of a pellet rifle manufacturer saying their rifle shoots at 1,400 f.p.s. In other words, although it sounds like it implies quality, what they don’t tell you is that those gears are not aligned properly and are set inside a cast pot metal gearbox.
Like everything else, in airsoft there are things that do work well and then there are the retailers who trade on the general ignorance of the buying public. They use buzzwords like metal gears to suck in the beginners. To mean something, the metal gears need to be run on pins of the correct size, have thrust washers to hold them in alignment and be inside a gearbox that can take the strain — and the whole reason for all of this is so you can get some benefit from that high-torque motor and uprated battery you also installed. If you aren’t going to do this in a systematic way, you might as well eat the metal gears, for all the good they’ll do by themselves.
I’ll stop here because this report is getting long. In the next installment, we’ll look at the airsoft powerplant, upgrades to batteries and motors, and the best way to get started working on airsoft guns.

Today is a special test of the C96, requested by blog reader RidgeRunner and seconded by several others. You want to see if the pistol will be more accurate with Daisy’s Avanti Precision Ground Shot, which is made expressly for the Avanti Champion 499 BB gun. More accurate than what? More accurate than the best BB tested in Part 3, which turned out to be the Daisy Premium Grade zinc-plated BBs that shot the tightest groups with this pistol?
We know that the Daisy Premium Grade BB averaged 395 f.p.s. with a total velocity spread of 18 f.p.s. (from 386 f.p.s. to 404 f.p.s.). RidgeRunner suspected the Precision Ground Shot would be faster in this pistol because it’s usually slightly larger and also more uniform. So, I first shot it over the chronograph.
Avanti Precision Ground Shot averaged 381 f.p.s. on a fresh CO2 cartridge. The velocity spread was 19 f.p.s., with a low of 371 f.p.s and a high of 390 f.p.s. The spread was 1 f.p.s. larger with this shot than with the Daisy Premium Grade BBs, and the average velocity was 14 f.p.s. slower. So, that part of the theory didn’t test out.
On to the accuracy test
I offered to do a blind test, but RidgeRunner trusted me to try my hardest with each BB: and that’s good because there’s a definite difference in appearance between the Premium Grade BBs and the Precision Ground Shot. The latter are not as shiny and appear more silver than steel in color than the Premium Grade BBs. I would have known which BB I was shooting.
The distance was the same 5 meters that was used for the first test, and I used the back of a chair to steady my hands as I held the pistol, just like I did before. This resulted in a very stable hold for every shot.
Daisy Premium Grade BBs
I shot 2 groups of 10 with each BB. The first group of Daisy Premium Grade BBs measured 1.115 inches between centers. Two BBs landed outside the black bull. The second group measured 0.644 inches between centers. That’s almost half the size of the first group, so you can see how much latittude there is with BBs — even at 5 meters.
Avanti Precision Ground Shot
Now, it’s time to test the Avanti Precision Ground Shot. This shot is ground to work best in the 499 BB gun, only. But you readers wondered if it would also be more accurate in the C96 BB pistol. To test that theory, I shot another 2 groups of 10 shots each at the same 5 meters. The first group measured 0.954 inches between centers. One BB was outside the black, and 2 more were right on the edge.
The second group I shot with this ammunition measured 0.556 inches between centers. It’s the smallest group of this session and would seem to lend credence to the Precision Ground Shot being more accurate than the Daisy Premium Grade BBs. However, the difference in group sizes of the 2 different BBs is not so great as to be overwhelming. Yes, both groups with Precision Ground Shot are tighter than the corresponding 2 groups made with the Daisy Premium Grade BBs, but the differences are not large. I don’t think they justify shooting the Precision Ground Shot in the pistol since they cost roughly 2.5 times more.
The Avanti shot went slower than the Daisy Premium Grade BBs and also varied more. However, the difference wasn’t much in either category.
The Avanti shot also appears to be slightly more accurate than the Daisy Premium Grade BBs. Again, the difference is very small, but it is there.
I’m surprised by these results. I predicted the Avanti shot would be faster because of its slightly larger size, but that it wouldn’t be any more accurate. So, I was wrong on both counts. I don’t think the difference between the two types of ammunition weighs in favor of using the Avanti shot in this gun, but it’s really a call the owner of the gun needs to make.
My thanks to RidgeRunner and others who asked for this test.

Today, we’ll look at the accuracy of the Legends C96 CO2 BB pistol, and I can sum it up in a single word: Spectacular! Those who like accurate BB pistols will want to put this one on their list.
I shoot all BB guns at 5 meters, which is about 16 feet, 5 inches. While that sounds incredibly close, it is the distance at which the Daisy National BB Gun Championship is shot; and if it’s good enough for the champions, it’s good enough for me. Besides, testing all BB guns at the same distance gives consistent results that can be compared across many tests.
I shot this test with my forearms rested on the back of a wooden chair, and the gun held in 2 hands. That eliminated as much of me as possible, giving the pistol a fair chance to shoot its best.
I used 50-foot smallbore rifle targets whose black bulls are almost 1.5 inches across. At 5 meters, they make perfect aim points for open sights. The C96 has a tapered post front sight and a V-notch in the rear. When the target is illuminated with 500 watts of halogen light, the sight picture becomes sharp and crisp, and sighting can be precise.
Daisy Premium Grade BBs
The first target was shot with Daisy Premium Grade zinc-plated BBs. The very first shot hit at the extreme bottom of the paper target, and I discovered one of the great features of this pistol. It has a tangent rear sight like the firearm it copies, and it was easy to raise the rear notch up just a bit. By sheer luck I got the elevation almost perfect on the first try, so I left the sights alone after that.
The next 9 BBs went into a shockingly small group, so I loaded one more BB into the magazine to make up for the first shot that was low. When I fired it, it was the only Daisy BB to hit outside the black after the sight adjustment. The 10-shot group measures 0.852 inches between centers. I think you’ll agree this is a very nice group of 10 from any BB pistol!
Next up were Crosman Copperhead BBs. They hit the target in the same place as the Daisys, and the 10-shot group measures 0.937 inches, which isn’t much different than what the Daisy BBs did.
Umarex Precision Steel BBs
Finally, I tried the Umarex Precision steel BBs. They rival the Daisys in precision and this time that was evident. Ten of them went into 0.863 inches, with nine of them in a much tighter bunch. Like the other 2 BBs, these also threw a single BB into the white.
Like the Mauser firearm it copies, this BB pistol has no provision for windage adjustments. Both the Mauser firearms I owned shot about a foot to the left at 25 yards, so I’m used to this. Some older pistols have sights that can at least be drifted to the side in dovetails, but not the Mauser. With this gun, you soon learn to apply Kentucky windage to lay your shots where you want them.
But let’s face it, this isn’t a realistic test for a BB pistol. BB gun shooters plink at cans. They don’t shoot groups at paper targets — at least not often. This pistol is easily a minute-of-Coke-can handgun out to 20 yards.
I found 2 things about the trigger pull when conducting this test. The first is that the trigger blade is located too close to the grip. That’s a part of the lack of ergonomics that the Broomhandle family of pistols all share, and there’s nothing to be done for it. This BB pistol is a faithful copy of the firearm, including a less-than-optimum grip.
The second thing I noticed was how hard the 2-stage trigger seemed to pull. Looking back at Part 2, I see that I did not measure the pull, so I got out the electronic gauge and measured it this time. Stage 1 requires between 2 and 3 lbs. to complete, and stage 2 breaks at an average of 7 lbs., 11 ozs. The range went from 7 lbs., 1 oz. to 8 lbs., 3 oz.; and the slower and more deliberate the pull, the greater the force required.
Even with that, though, the pistol is blisteringly accurate. And the blowback is pleasant. It’s nothing like the snapping recoil of a 7.63mm Mauser cartridge. So, there’s a benefit of shooting the BB gun over the firearm.
Umarex has a winner, here. Their Legends airguns are all remarkable guns, and the C96 takes its place among them proudly. Not only is it realistic-looking, it gets an astounding number of shots per CO2 cartridge; and, as we now see, those shots all go to the same place.
Let’s look at the velocity of the Legends C96 CO2 BB pistol. It’s advertised at 380 f.p.s., and we know that it has blowback. So, it’ll be interesting to see just how powerful this pistol really is, as well as how many shots it gets.
The first BB I tested was the Crosman Copperhead. They were tested when the CO2 cartridge was fresh, which boosted their average velocity a few f.p.s. They averaged 402 f.p.s, with a spread from 392 to a high of 409 f.p.s. At the average velocity, Copperheads generated 1.83 foot-pounds of muzzle energy.
I found the magazine very easy to load. Pull the follower all the way down and twist the tab into a slot to lock it back, then the BBs are dropped into a trough where an opening dumps them into the single stack slot in the mag. Release the follower, and the gun is loaded. I found the rated capacity of 19 BBs to be spot-on.
Daisy Premium Grade zinc-plated BBs
Next up were Daisy Premium Grade zinc-plated BBs. I though they might be a little faster than the Copperheads, but they weren’t. They averaged 395 f.p.s., with a low of 386 and a high of 404 f.p.s. At the average velocity they produced 1.77 foot-pounds of muzzle energy.
All the time I was chronographing the gun I was also counting all the shots. I noticed that when you load a new magazine, the first shot will always be a blank. That’s because of how the gun’s feed mechanism works. I did count those shots in the total because they used up gas the same as if a BB had been shot.
Umarex Precision steel BBs
The final BBs I tested were the Umarex Precision steel BBs. They averaged 394 f.p.s. with a low of 385 and a high of 404 f.p.s. That parallels the Daisy BBs pretty close. At the average velocity, these BBs produce 1.76 foot-pounds of energy at the muzzle.
During the chronographing session, I was waiting a minimum of 10-15 seconds between shots to allow the gun to recover from the cooling effects of the gas. But after the 3 test strings were finished, I continued shooting Umarex steel BBs to see how many good shots there are on one CO2 cartridge. I went much faster during this shooting, with less than a second between each shot. I think this is closer to the way most shooters will use the gun.
I kept expecting the pistol to run out of gas at any time, and it kept right on shooting and surprising me. Finally, at shot 103, I chronographed an Umarex BB going out at 336 f.p.s. While that is slower than the recorded average, you have to take into account the fact that I was now firing the pistol very fast and allowing it no time to warm up. So, an unexpected finding was that this pistol doesn’t suffer as much from the cooling of the gas as most CO2 guns. There normally would be at least a 100 f.p.s. velocity drop when shooting this fast.
Finally, after shot 123, the hammer didn’t cock for the first time. I cocked it manually and kept on shooting, but it failed to cock again after a few more shots. The gun was now out of gas. Had I wanted to get more shots from it, all I needed to do was slow down my shooting to allow more time for the gun to warm up. I think the shot count could easily be stretched out to 140-150 shots that way.
So, the pistol shoots a little faster than advertised, and it gets a very respectable number of shots from a CO2 cartridge. That’s 2 big plusses for the gun.
Next on the schedule is accuracy testing. I’m looking forward to that! I have to tell you that this C96 is a very neat CO2 BB pistol. Of course, it isn’t ergonomic, but neither is the C96 firearm it copies. It’s not supposed to fit you well — it’s supposed to look like the real deal, and I think it does that very well.

Let’s cut to the chase. The title of this report says Legends C96 CO2 BB pistol, but Americans are going to call this a Broomhandle Mauser because of the shape of the pistol grip. The Legends part comes from the Umarex line of replica air pistols.
Before we continue, I want to express my concern about the Umarex lookalike airguns. I got a CO2 Colt M1911A1 pellet pistol when they first came out, and soon I had 4 different M1911/1911A1 firearms to go with it. Then the PPK/S BB pistol hit the market, and I got one of those. Not long after that, I added a .22 rimfire PPK/S to my firearms collection. Then came the Walther Lever Action rifle. Good, I thought. I’ll never buy the Winchester 30/30 1894 that it is patterned after. But I didn’t need to, because Edith did.
Then came the Magnum Research Desert Eagle pellet pistol. I knew I would never own the firearm version of that big hand cannon, but 2 years ago I got an IMI .357 Magnum Desert Eagle.
Of course there was the Makarov BB pistol that I used to train Crystal Ackley to shoot on American Airgunner. I say “train” advisedly; because after her first magazine, she was out-shooting me! That pistol spawned the purchase of both a 9mm Bulgarian Makarov, as well as the genuine Makarov firearm that the Russians at IZH turned into a BB pistol.
And just last year, Umarex came out with the Parabellum P08. I had already owned a junker Luger in the early 1970s, and I swore that I would never own another one. Well, my resolve being what it is, this past Christmas, Edith gifted me with a 1917 Erfurt P08 that is definitely not a junker!
And, now, I must confess that in my youth I’ve owned not 1 but 2 different low-grade Broomhandles. Both were in 7.63mm Mauser caliber, and neither one was particularly accurate. I reloaded for the last one, which might have been a large part of its problem. And here’s the Legends C96 Broomhandle! Lordy, I can’t afford to keep this up! I just hope they don’t bring out a Colt Walker next!
Is it a C96?
Technically, this pistol is not a C96. It is a copy of the M32/712 Schnellfeuer (German for rapid fire) pistol that has a selector switch on the left side of the gun for semi- and full-automatic operation, but it’s just a cast detail and is entirely non-functional. It also has a detachable magazine hanging down in front of the triggerguard, just like the 20-shot Schnellfeuer.
The C96 never had the detachable magazine or the selector switch. It has an internal 10-round magazine that’s loaded from the top of the gun through the ejection port with 10-round stripper clips. The bottom of the C96 magazine is flush with the bottom of the triggerguard. It’s true that the C96 magazine floorplate can be removed and a separate, detachable magazine can be installed, but these were never a popular option for the C96. I suppose only collectors and students of history will know the difference, so I’ll call this pistol the C96 from this point on.
The Legends C96 is a 19-shot BB pistol powered by CO2. The CO2 cartridge and BB magazine are housed together in a single removable magazine unit that’s located in front of the triggerguard. Press a button on the right side of the receiver to release the mag.
There’s a lower magazine cover that hides the CO2 screw and the CO2 cartridge. This is something BB gun shooters are very sensitive about, so it was a necessary feature that completes the look of the gun.
The magazine has been removed, and the lower cover is off. You can see the selector switch in this photo.
When the CO2 cartridge is installed and the magazine is loaded, you might think the pistol would be muzzle-heavy like the firearm, but I don’t find that to be the case. This BB pistol is light enough that there’s very little muzzle heaviness. And it’s light because it’s made with a lot of synthetics. But this stuff is dense, strong and difficult to tell from metal. A matte finish makes it even more difficult to identify.
The pistol grip butt is slotted for a shoulder stock, just like the firearm. Those stocks are hollow wooden holsters with steel attachments that lock into the pistol at this point — forming a small carbine. However, since the gun is made of synthetic, I’m guessing a shoulder stock will not be an option since it would invite fractures at this slot.
Not having a shoulder stock is not a great loss, though. I’ve fired the Broomhandle as a carbine and found it to be very inaccurate. Of course, that could just be the ammo I used, once again. But any pistol/carbine is a compromise, and none of them have a reputation for accuracy or even utility. It would be nice to have an authentic holster in which to carry the pistol, though.
Since the pistol is made to also be a carbine, the rear sight is an adjustable tangent leaf that adjusts up to 1,000 meters. The BB pistol has the same markings on its tangent sight leaf, though no shooter should ever expect to shoot a BB that far unless it’s downward from a high platform. But it does give you the option of elevation for close-range shooting. There’s no windage adjustment on this BB pistol or on the Mauser firearms.
This pistol has true blowback! Just like the firearm, the bolt handle comes back with each shot and cocks the hammer, so every shot is single-action. You must cock the hammer for the first shot. Some writers have suggested this is not a blowback pistol, but I think they’re not familiar with the C96 Mauser action. It doesn’t have a conventional slide like many autoloading pistols. The bolt is what moves to cock the hammer; and on the firearm, it also ejects the spent cartridge and strips a fresh one from the top of the magazine.
So, the Legends C96 is a true semiautomatic CO2 pistol. The trigger-pull is light and crisp. Unfortunately, unlike the firearm, the bolt does not stay open after the last shot’s been fired, so it’s up to the shooter to know when the last BB has been fired. You can continue to pull the trigger without BBs if you like.
The barrel of the Mauser firearm is dovetailed to the frame and does move when the gun recoils. It’s how the designers delayed the opening of the bolt until after the high-pressure gasses were exhausted. It also allows the pistol to tolerate ammunition with a wider range of power. The BB pistol looks the same as the firearm, but that’s just the casting details. The barrel does not move.
Although it has blowback, this BB pistol will not recoil like the firearm. A Broomhandle Mauser really snaps your hand back, despite being chambered for light cartridges like the 7.63 Mauser and the 9mm Luger. That’s because the bore is high above the grip, so the recoil has nothing to slow it down. I remember the recoil as one of the bad points of a Broomhandle.
Yes, the blowback of this BB pistol does give the shooter a sense that the gun has fired, but there’s no heavy snap to your wrist. Trust me, this is better!
The safety is identical to the Mauser firearm part and works the same way. I found it to be positive and much easier to apply than the firearm safety.
When Herr Wonish of Umarex told me last February this pistol was coming, I told him I was eager to see it. Now it’s here, and I intend examining it thoroughly!

It’s accuracy day for the Beretta model 84 FS BB pistol, and some of you have been eagerly awaiting this day! I decided to shoot 3 different BBs in the gun just to give you a general idea of how well it groups.
Because this is a BB gun, the shooting distance was 5 meters, which is 16 feet, 5 inches. I sat backwards on a chair, resting my forearms over the back, so the pistol was fairly steady. I selected a 10-meter rifle target for this session because the smaller bull seemed appropriate for the shorter distance.
After installing the CO2 cartridge and loading the first 10 BBs, I tried to shoot the target and the gun wouldn’t fire! What was wring? I knew this was a double-action-only trigger, and it should have worked. Right?
Wrong! This trigger is not DAO. It only feels like one! It’s really a single-action trigger that requires the hammer to be cocked before it’ll work. You can squeeze the trigger all day and nothing will happen until the hammer is cocked. So, with this little problem out of the way, the test could begin.
Crosman Copperhead BBs
First up were 10 Crosman Copperhead BBs. As I shot, I noted that the pistol was very steady in my rested hands. And the target shows that…I think. Ten Copperheads went into 1.521 inches at 5 meters. But note the 2 holes that are apart from the main group. Eight of those BBs made a group measuring 0.78 inches.
The farthest of the 2 holes that are apart from the main group — the one to the extreme right — was a called flier. My hand twitched to the left as the shot fired. The other one, though, was held just like all the rest.
Daisy Premium Grade BBs
Next I tried 10 Daisy Premium Grade BBs. Like I mentioned in Part 1, they’re top-grade BBs that always deliver the goods. This time, 10 of them went into 1.114 inches. There were no called fliers, and the group is fairly well centered on the bull.
The last BB I tried was the Umarex precision BB — another top-grade BB. Ten of them grouped in 1.28 inches, with 9 going into 0.998 inches. There were no called fliers in this group, either.
As I told you in Part 2, the trigger-pull on this pistol feels very much like a double-action pull. That’s one where the trigger first cocks the hammer before releasing it to fire the gun. It “stacks” or increases in effort significantly toward the end of the pull, like a vintage Colt double-action revolver. Once you learn how to use that, it helps with accuracy. The pistol is actually stabilized before firing.
This little Beretta is a fun BB gun, make no mistake. I found it trouble-free and easy to use. The sights are right on, and there are no quirks in the operation. If you like BB repeaters, this would be one to consider!
by Tom Gaylord, a.k.a. B.B. Pelletier
Today, we’ll look at the velocity of the Beretta model 84 FS BB pistol. We’ll also look at the trigger and the shot count.
Of course, the first step to shoot a CO2 BB pistol like this one is to install a fresh CO2 cartridge. And when you do, never forget to put a drop of Crosman Pellgunoil on the tip before piercing. The oil will be blown through the gun, coating every seal on the inside and sealing it tight for a long time. I found the cartridge sealed immediately after it pierced, so this pistol is conventional in that respect. Remember — once the cartridge is pierced and the gas stops hissing, you don’t want to tighten the screw any more or you’ll soon tear the face seal that the cartridge butts against, creating a leak.
The BB magazine holds 17 BBs comfortably, and 18 can be forced in. I loaded them one at a time, but in this mag, they load easily.
Umarex Precision BBs
Thye first BB I tested was the Umarex Precision BB. In past tests I have found this BB to be one of the 2 top BBs on the market for precision and size uniformity. They tend to be larger in diameter, which means they give the best velocity.
These BBs averaged 368 f.p.s. for 10 shots, but I did notice the gun is very susceptible to velocity dropoff if the shots are fired fast. When I waited at least 10 seconds between shots, the velocity held steady; but if I fired 2 shots quickly, the second one was always much slower. In one test, the first shot went 372 f.p.s. and the next shot…fired a second later…went 358 f.p.s.
The fastest shot in the string went 385 f.p.s. and the slowest went 356 f.p.s., so the spread was 29 f.p.s. However, the first 3 shots on a new cartridge always go much faster than the average. If we eliminate those 3 shots from this string, the average drops to 363 f.p.s., which seems like a more reasonable average.
Daisy Premium Grade BB
Next I tried the Daisy Premium Grade BB that’s the other top BB on the market. These BBs are also very uniform and very consistently sized. Ten of them averaged 357 f.p.s., with a spread from 350 to 373 f.p.s. That’s a 23 foot-second spread.
The Daisy Premium Grade BB is as good as BBs get, unless you opt to buy the special Avanti Precision Ground Shot that are the finest BBs available today. But they only show their advantage when used in the equally superior Daisy Avanti Champion 499 BB gun. If you shoot them in anything else, you’re wasting money as sure as someone who loads target rimfire ammo into a semiauto sporter.
Crosman Copperhead BB
The final BB I tried was the Crosman Copperhead BB. This BB is not as consistent as the other 2 because the diameter varies, causing velocity variations. You probably won’t find any flat spots on these BBs, but the diameter inconsistency puts it into the second rank for both velocity and accuracy.
In the 84 FS, Copperheads averaged 348 f.p.s., but the spread is very revealing. The low was 314 f.p.s., and the high was 375 f.p.s. That makes the spread 61 f.p.s.
After shooting 64 BBs (there were many that didn’t register on the chronograph, plus I filled the magazine with each type of BB and then shot the rest of them without recording the velocity), the next few Daisy BBs went 317, 306, 301 and 294 f.p.s., respectively. So, the liquid CO2 was exhausted at this point, and the gas pressure was dropping.
Shot count for a CO2 cartridge
I continued to shoot the pistol until the blowback no longer worked. That happened at shot 78, so that’s the number of shots you can get from the gun. By that time, the gun is shooting the Daisy BBs in the mid-200s, meaning that about 100 f.p.s. have been lost since the cartridge was fresh.
The blowback on this pistol is faster than the blowback on most air pistols, because the slide doesn’t come back as far. When the CO2 cartridge is fresh, you just feel an impulse when the gun fires, but I wouldn’t call it realistic recoil. But as the gas pressure lowers, the slide starts cycling slower and you do feel the recoil.
Remember that I told you in Part 1 that the trigger felt strange? I said it felt like a double-action-only trigger instead of the single-action trigger that it is. Well, this time I tested it and proved that’s how it feels. Despite the slide cocking the hammer for each shot, the trigger is still very long and heavy.
The first-stage pull runs about 4 lbs., and stage 2 breaks at 9 lbs., 9 oz. every time. Pull the trigger slowly, though, and stage 1 becomes creepy, plus stage 2 increases by a full pound. This will be an interesting handgun to shoot for accuracy!
Evaluation thus far
I like how the 84 FS holds. It’s small, but not tiny. It fills the hand with its wide grip frame. But that trigger will be something to contend with. The trigger on my Micro Desert Eagle .380 firearm pistol is also DAO and also challenges me when I shoot farther than 20 feet; but it’s smoother near the end of the pull. This trigger stacks up a lot at the end of the pull. We’ll see!
