Today, we’ll look at the accuracy of the Air Arms TX200 Mark III at 50 yards. I can tell you that I learned a lot from this test. But that will all be summarized as we go. Let’s get started!
I shot the new TX directly off the same sandbag that was used at 25 yards. As you remember, I showed (after much coaxing from you readers!) that the TX shoots as well or better when rested directly on sandbags as it does with an artillery hold. The bag was crossways to the rifle, so the contact with the stock was minimized.
The day was perfect for the test. Not a breath of wind the entire time I was on the line!
The rifle is mounted with the AirForce 4-16X50 scope, which was selected so I could conduct another test for reader Duskwight after the regular test was completed. This scope is clear and sharp; and at 50 yards, I was able to bisect the small bullseyes with the reticle.
The rifle was still zeroed for 25 yards, so it had to be adjusted for 50 yards before anything else could happen. The first shot landed 3-1/4 inches low and 1-1/2 inches to the left. It then took another 2 shots before I was reasonable on the target. Then, I fired the first group with H&N Baracuda Match pellets. Ten landed in a group measuring 1.562 inches. It’s a fairly round group, but not as small as I would like from this rifle. So, I switched pellets.
JSB Exact Monsters
Next I tried some JSB Exact Monsters, which weigh 13.4 grains in .177 caliber. They went all over the place. When I went dowrange to retrieve the target, I saw that they were tumbling or yawing. They must be too heavy for the velocity the TX is able to generate.
Crosman Premier heavy
The third pellet I tried was the Crosman Premier heavy. I meant to bring Crosman Premier lites, but I grabbed the wrong box when loading up for the range. Fortunately, the heavy pellet was wonderful! Ten of them gave me a group that measured 0.658 inches between centers — or about as good as a top-flight PCP can do at the same distance! This is phenomenal accuracy for any air rifle at 50 yards!
First lesson learned
The new TX200 Mark III is every bit as accurate as my TX that’s well broken-in. No accuracy has been lost over the years, and the rifle can shoot this well right out of the box!
With lesson one under my belt, I adjusted the scope to lower the point of impact and moved to the next bull. The first shot landed where the last group was, then the pellets moved to the new sight adjustment.
Second lesson learned
Some scopes have stiction. After adjusting them, it’s best to shoot a couple shots to vibrate the reticle to its new location. I knew that, but made the mistake anyway. So, I’ve included the first shot, along with the group, to show you what it looks like. If this group had been as small as the one before, that first shot would really stand out. But I lost my concentration on this one and wasn’t holding the rifle as softly as I might have. This group of 10 measures 1.435 inches between centers, which isn’t that far from the first group of H&N Baracudas!
The second group of Premier heavies opened to 1.435 inches. That’s more than double the size of the first group! Top hole to the left of the pellet was the first shot, which I disregarded, after the scope was adjusted.
Third lesson learned
While a rifle may be capable of shooting 10-shot 50-yard groups smaller than one inch, it may not do it every time! That small group may represent what the rifle is capable of, but not what it will always do.
Duskwight, our blog reader from Moscow, asked me to test the difference between a rifle shot with a low-power scope and the same rifle shot with a high-power scope. In other words, does magnification improve a rifle’s ability to group?
Well, common sense tells us that it does. Right? I mean, surely, if you’re able to parse the target to a finer degree, you must be able to group your shots closer together. Right? That’s what this test will determine.
That’s why I used a 4-16x scope on this rifle. I’d been shooting with 16x to this point, so now I dialed the power back to 4x and shot another group.
Wow! At 4x, the intersection of the crosshairs almost completely covers the small bullseye at 50 yards. As I shoot, I’m almost certain how this test is going to turn out. And it does. Ten shots on 4x with the same Premier heavy pellets landed in 2.208 inches. Looks like I was right about what low magnification would do.
The third group of Premier heavies — shot with the scope set to 4x — was 2.208 inches between centers at 50 yards. That’s quite a difference from the previous group, even though that group was already admittedly large.
But something nagged me about this group. I knew in my heart that I’d not given the rifle my best. I knew this group was going to be bigger than the last one while I was shooting it, so I was even sloppier with my hold.
It probably sounds like I need medication to suppress my dual personalities while at the range, but I assure you I’m not talking to myself — at least not loud enough for others to hear. What I’m doing is a little soul searching while I’m still out at the range and have the time to do something about it.
I adjusted the scope back to 16x and shot another 50-yard group. This time, I did everything the way I should have. The hold was completely relaxed. I fully expected to be rewarded with another of those sub-inch groups, but that didn’t happen. This time, I shot a 10-shot group measuring 1.935 inches between centers. Oh, well! I was probably tiring out from all the concentration.
Fourth lesson learned
Sometimes, you just can’t will the results to happen the way you would like. I put my whole heart into this group, and this is what I got. Maybe that’s what it feels like to be 66, dried-out and ready for the old-folks home!
Fifth lesson learned
I called that first great group of Premiers a screamer. Now you see why that is.
Nevertheless, I owed it to Duskwight to try the rifle on low scope magnification one more time, and this time to do my very best. So I did. This time, 10 pellets went into a group that measures 1.481 inches between centers. That’s right, it’s SMALLER than the group shot on 16 power! I noticed that the bull was just visible behind the crosshairs; and if I really tried, I could hold on the target in exactly the same way every time. Apparently, I did, because this group fired on 4x is smaller than the previous group that was fired on 16x.
Sixth lesson learned
Although it isn’t conclusive, it looks like you can shoot just as accurately on low scope magnification as you can on high magnification if you take the time to do things right.
Seventh lesson learned
Looking at both groups fired on 16x and both groups fired on 4x, it sure looks like the point of impact never changed! Some of you have asked about that in the past. The design of the scope determines whether the impact point will move when the scope’s power is changed, but these days a lot of variable scopes stay right where they were when the power’s adjusted.
Eighth lesson learned
Of the five groups fired with Premier heavy pellets on this day, only one is smaller than one inch. And it’s significantly smaller! When you see those great groups in the future, you must ask yourselves what the rest of the groups look like.
Ninth lesson learned
I may be old and dried-out, but I can still shoot — a little. I get tired as the shot count increases, so that needs to be factored in to my tests from now on.
I’m very pleased with what this new TX200 Mark III has done so far. I think the rumors that the TX quality may have slipped are just that — rumors! Individual guns may have problems; but overall, the TX200 is one fine air rifle. Next, I plan on mounting a red dot sight and testing it for accuracy, again, to see what the differences are.

Today, I’m testing the Crosman MTR77NP scoped air rifle for accuracy at 25 yards. This is going to be a very different accuracy report, for I have no targets to show you. Well, there is one target, but it wasn’t shot with the test rifle.
In the last report, I mentioned that I wanted to mount a different scope on the test rifle and test it at 25 yards. I thought the Bug Buster 3-9x scope would be a good one, and I also shimmed under the rear ring because the rifle was shooting low in the 10-meter test.
I thought the rifle would group about 3 times larger at 25 yards than it had at 10 meters, but I also hoped some pellets might remain tighter than that. What happened, however, was just the reverse. Instead of 3-inch groups I got 5- to 6-inch “patterns.” I won’t call them groups because not all pellets fired even hit the target trap. And when that happens, I stop shooting that particular pellet immediately.
Crosman Premier lites
First up was the pellet I thought had the best chance to do well — the 7.9-grain Crosman Premier. They had done well at 10 meters with just 2 pellets outside the main group. Had they held to my 3X size increase, they would have grouped into about 2.2 inches; but when the third shot landed 6 inches away from shots 1 and 2, and then shot 4 landed 5 inches from that pellet, I stopped shooting.
I checked the scope mount to see that it was still tight. It was, and I’m pretty sure this scope is a good one because it has done well in other tests on other airguns. So, Premier lites are out.
H&N Baracuda Match
Next, I tried some H&N Baracuda Match pellets. But they were no better. They hit the target lower than the Premiers, and 3 shots landed in about a 5-inch pattern. Then, one pellet missed the target trap altogether. I stopped shooting after that shot, but I wasn’t done with this pellet.
I got the Air Venturi Pellet Pen and Seater and deep-seated a couple Premier lites to see what affect that would have. The point of impact changed, but the accuracy didn’t improve. And when the third shot missed the trap, I stopped shooting Baracudas.
The next pellet I tried was the RWS Hobby, which gave such a nice, round group at 10 meters. Two shots landed together, and I thought we were on the right road; then the next shot hit about 6 inches away from them. The 4th shot missed the trap altogether, and I stopped shooting that pellet.
By now, I was in a quandary. Was it me or the gun or the scope? I went back to 12 feet from the target and confirmed that the scope was still shooting to the same point, then I went back to 25 yards and tried an RWS Superdome. I had confirmed at 12 feet that the Superdome would be on paper at 25 yards and the first shot was. It landed high, but in good enough position to keep shooting. The next shot missed the paper altogether and I don’t know where it went. That was it for Superdomes.
What to do?
By this point I was really shaken. My confidence was ebbing fast and I needed to end this session on a high note. So I grabbed my Beeman R8 Tyrolean and a tin of Air Arms Falcon pellets and shot a final group of 10 at 25 yards. This one turned out good, as I expected it would. That’s where today’s target comes from. It isn’t the best group I’ve shot with the R8, but it’s a darn sight better than I did with the MTR77NP. Ten shots went into 0.41 inches.
I need some time to think about why this rifle might be performing like it is. If one of you made a report like this to me, I would tell you to check the scope because that sure seems like what it is. But I did check the scope and found no problems. The one thing left to do is to crank the elevation down all the way and all the way to the left and shoot a group. If it tightens up, then it was the scope. If not, it’s either the mounts or the rifle.
A little tip
What I did with the R8 today is a handy tip to remember. Sometimes the problem is you — or you wonder if it might be. Shooting a good group with a rifle of known accuracy is the best way to rule that out.

I’m writing this extensive report to fully explore the fabulous Air Arms TX200 Mark III, which is without a doubt one of the finest spring-piston air rifles in the world! The good news is that it’s still available today. The better news is that it’s everything it’s cracked up to be! Writers have a few trite phrases to convey quality in the airgun world. “As good as a TX 200″ is one of them, and it’s very high praise.
There are 9 links above that will take you all the way back to the beginning, when I started by testing my own well-broken-in TX 200. But now I’ve shifted over to a brand-new rifle that Pyramyd Air sent to me to test. Some readers wondered if my rifle, which is so well-used that it might be performing above the bar, so to speak, because of the use it’s had. They wanted to see a rifle that’s being made today, and also one without all the wear on the parts. That’s what we’re testing now — a brand-new TX whose only shots are the ones you have witnessed on this blog.
The TX has no sights and must be either scoped or have some other kind of optical sight mounted. One of the tests we’re going to do with this rifle is to mount a red dot on it and see what that does for it. Blog reader Mannish from Mumbai asked for that test a long time back.
We’re also going to test the effects of shooting the gun at 4X and again at 16X with the same scope. Reader Duskwight asked for that — to see if the increased magnification would affect the group size. I also want to see if changing the magnification changes the point of impact, so that test will be a twofer.
I’m leading up to the scope I chose for this test. I might have selected the same Hawke 4.5-14X42 Tactical Sidewinder that was on my TX when I tested it, but that didn’t give me all the magnification I wanted for Duskwight’s test. So, I selected a vintage AirForce 4-16X50 scope, instead. Mine is older than the model being sold today, but the specifications are essentially the same. For a mount, I selected a nondescript 1-piece mount. I chose it because it has a vertical scope stop pin for the TX scope stop holes, plus it has the height needed for the scope’s objective bell to clear the spring tube. I have no idea who made it.
I started sighting-in at 12 feet, putting 3 pellets into the target and adjusting until they were in line with the center of the bull, more or less. They were high, so I cranked down about 4 complete turns on the elevation knob, knowing that back at 25 yards the gun would be shooting higher than at 12 feet.
When I shot the first pellet at 25 yards, it was still about 1.5 inches high, so a couple more turns down on the elevation knob brought it to the center of the bull. As always, I tried to intentionally keep the pellets from striking the center of the bull, as that erases my aim point very quickly. The sight-in was now complete with about 7 shots being expended.
All of today’s shooting is at 25 yards, which is really close for a TX. I rested the rifle directly on my sandbag, with the bag turned sideways, so the rested area touched about 5 inches of the forearm. I used an ultra-light hold, and the groups showed the results. I selected a couple pellets that had done well in the test of my personal TX and one that had never been tested for accuracy before.
H&N Baracuda Match
The first pellet was the one I used to sight-in the rifle — the H&N Baracuda Match. It was landing to the left of the aim point and in the center of the bull for elevation. Ten shots landed in a group that measures 0.417 inches between the centers of the 2 pellets farthest apart. That’s well within the range fired by my personal TX at 25 yards.
JSB Exact RS
Next, I tried a pellet I haven’t tried for accuracy in the TX — at least not that I can remember. The JSB Exact RS dome is a very lightweight pellet for a rifle this powerful. The first shot landed about 1.5 inches above the spot where the Baracudas were hitting, but it was still on paper, so I continued to shoot. Each shot that followed seemed to drop a bit lower on the paper, and as I was shooting I discovered something important. The rifle shoots this pellet very well, but it is extremely hold-sensitive. Moving the rifle a quarter-inch on the sandbag makes a tremendous difference. So, I was able to adjust the hold carefully and get the pellets to land closer together.
I think the RS pellet can be made to shoot, but it isn’t worth the effort when there are other pellets that shoot even better without all the fuss. The 10-shot group I got measures 1.501 inches between centers, which is terrible; but 6 of those pellets were the ones I took special pains to hold exactly the same, and they measure just 0.496 inches between centers. That’s the potential of this pellet when you handle the gun like it’s a soap bubble!
Crosman Premier heavy
The last pellet I tested was the Crosman Premier heavy. The group was a phenomenal 0.333 inches between centers! That’s slightly better than the best group I shot with my own TX at 25 yards, but the difference is only 3 one-thousandths of an inch and could easily be hidden by an error in measurement. So, the 2 rifles are equivalent.
I could have shot other pellets and shown you more targets, but by now you’re getting the picture. The new TX is the same as it has always been — one of the finest and most accurate air rifles on the market.
Next, I’ll test this rifle at 50 yards. I’ll do essentially the same test that I did with my own TX at that distance, but then I’ll add the 4-16X test. That will tell us if there’s an advantage to more magnification, and it will also show if the point of impact changes as the magnification changes.
After that test, I plan on mounting a red dot sight on this rifle and testing it at 25 and 50 yards. I think that will end the test of this rifle, unless something else comes up.

Today, we’ll look at the first of 2 accuracy tests planned for the Crosman MTR77NP scoped air rifle. As you know, this rifle has no open sights; so, the first thing I did was mount the Centerpoint 4X32 scope that’s included with the gun. That went quick because the scope caps have 2 screws each, but there was no slippage of the scope in the rings during this test.
The scope is very bright as you would expect a 4X scope to be, but at the 10-meter distance I shot in this test, it was fuzzy. The parallax is fixed for a further distance that isn’t indicated on the scope. I can tell from examination that it’s set farther than 25 yards.
I’m testing at 10 meters today and will take the best pellets into the next test, which will be at 25 yards. The first pellet up was the 7.9-grain Crosman Premier. You will remember from the velocity test that the test rifle shoots considerably slower than its advertised velocity of 1,000 f.p.s. with lead pellets. It went an average of 866 f.p.s. with 7-grain RWS Hobbys.
I discovered that the rifle is shooting low, even with the scope adjusted up high. For the next test, I’ll shim the rear scope ring. That should raise the pellet up far enough.
Crosman Premier lites
At 10 meters, 10 Premier lite pellets made a group that measures 0.721 inches between centers. The group has a main group of 8 pellets within it and 2 flyers, though there were no shots that were pulled. This is a case where a better scope might do better on target because the image was so fuzzy that I might have been off the aim point by 1/8 inch at times.
The MTR77NP fires with a solid thump. There’s no vibration, and the shot cycle is very quick. The recoil through the butt isn’t sharp the way it is on many gas-spring air rifles. And the A2 stock seems to be ideal for handling the recoil of this rifle without stinging your cheek.
Now that I’ve shot the gun for accuracy, I can tell you the trigger-pull is very long in stage 2. The pull length of stage 2 is supposed to be adjustable, but I turned in the screw about 7 full turns and nothing changed. It feels like a placebo screw; or if it does adjust anything, the effect is very small.
H&N Baracuda Match
The next pellet I tested was the heavy H&N Baracuda Match. This pellet showed some promise in the velocity test, and I thought it might do well in this rifle. Ten of them went into a group that measured 0.982 inches between centers. Like the Premier lite, there were flyers outside the main group, though I did not see them when shooting. I’m beginning to think that the next test needs to be conducted with a different scope.
The scope mounts had loosened by this point in the test. The rings remained tight, but the screws that attach the rings to the base on the rifle loosened up. I tightened them and also checked them after every 5 shots from this point on.
Next, I tried 10 RWS Hobby pellets. They went much lower and also to the left. They actually missed the target paper. The group was round and measured 0.826 inches between centers.
Crosman SSP Hollowpoint
I did check the Crosman SSP hollowpoint that was the lead-free pellet I tested in the velocity test, but after 2 pellets missed the target backer altogether, I stopped shooting. Not the pellet for this rifle.
JSB Exact Express
The last pellet I tested was the 7.87-grain JSB Exact Express dome. I haven’t had much luck with this pellet in the past, but I keep trying it just in case. Alas, the MTR77NP doesn’t like it, either. Ten pellets went into a vertical 1.661 inches at 10 meters. Another pellet to not use in this rifle.
Evaluation so far
I like the way the rifle feels when it fires. It has good power and a solid thump when it fires. The trigger-pull is long but not too creepy.
The scope leaves a lot to be desired. I think I’ll replace it with a Bug Buster 3-9X scope for the next test, and I’ll shim the rear scope ring before mounting it on the rifle. That should give the rifle the best chance to do well at 25 yards.
Obviously, the pellets to try are the Crosman Premier lite, the H&N Baracuda and the RWS Hobby. The Hobbys will be at their maximum recommended distance, but they may surprise us.
If you like black rifles and have been considering the MTR77NP, I think it’s worth a look. We’ll know better after the next test.

We’re back to the BSA Scorpion 1200 SE. When we last tested it, we looked at the velocity and discovered this is a 30 foot-pound air rifle. So, its primary purpose is hunting. I thought that meant I should test some heavy .22-caliber pellets, but I also included a middleweight.
This test was done at 50 yards. I never shot the Scorpion indoors at 25 yards because it’s so loud. I went straight from mounting a scope to shooting at 50 yards. As it turned out, that cost me several more shots than normal to get on paper.
I scoped the rifle with the UTG 6-24X56 AP scope with illuminated reticle.
I knew the scope would be right for the Scorpion because BSA PCPs are very accurate. I wanted a lot of power in the scope to compliment the long-range capability. This scope gave me what I was looking for.
The first pellet I tried was the 21-grain Beeman Kodiak. The first group wasn’t good because the wind kicked up just as I fired a couple of the shots. Sure enough, the 10 holes had a horizontal spread. They measure 1.006 inches between centers, which isn’t bad, but I felt this pellet deserved a second chance.
The second group of 10 Kodiaks measures 0.926 inches between centers. Although that isn’t that much smaller than the first group, this group is rounder; and I feel it’s representative of what Kodiaks will do in this rifle.
Eun Jin dome
I said during the velocity testing that the 28.4-grain Eun Jin dome would probably be good if you were seeking the maximum knockdown power at long range. They developed an additional foot-pound of muzzle energy. They’ve never been the most accurate pellets, but in some PCP rifles they do deliver credible accuracy.
Not in the Scorpion 1200 SE, though. The Eun Jin gave a large groups with a pronounced vertical spread. It measures 1.488 inches between centers and was the largest group of the test. I don’t recommend this pellet in the Scorpion 1200 SE.
JSB Exact Jumbo Heavy, 18.1 grains
Next, I tried the JSB Exact Jumbo Heavy domed pellet. This one is between the medium-weight JSB Jumbo and the heavier Beeman Kodiak, so it gives better velocity with some good power retention. If it shoots at least as well as the Kodiak, it would be worth choosing.
But it doesn’t just shoot better — it shoots WAY better than the Kodiak in the Scorpion 1200 SE. Ten pellets made a group that measures 0.792 inches between centers. The group is very round, as you can see, so we know this pellet is a keeper!
JSB Exact Jumbo 15.9 grains
The last pellet I tried was the 15.9-grain JSB Exact Jumbo. Sometimes this pellet is the best in a PCP rifle, so it had to be tried. This time, however, was not one of those times. Ten pellets made a 1.332-inch group that was not as tight as the Kodiaks or the 18.1-grain Exact Jumbo Heavys. And no wind caused the horizontal spread of these pellets.
The BSA Scorpion 1200 SE certainly has the power and accuracy needed to be a good hunting rifle. I like the way the stock balances in my hands when shooting, as it’s heavy at the muzzle. I don’t care for the fact that it needs 232 bar of fill pressure because that drains even a carbon fiber tank quicker than a 200 bar fill. It does, however, get a reasonable number of powerful shots per fill (25).
The 10-shot magazine is flawlessly reliable. There was never a misfeed in the entire test. And the magazine is below the top of the receiver, so it never interferes with the scope. The trigger is light enough, but I don’t care for the stage 2 creep that I found impossible to adjust out.
I would recommend this rifle to all who like its looks and features.

Today, we’ll test the Umarex Fusion CO2 rifle at 25 yards. And today was also supposed to be the day I tested how long you have to wait to remove the CO2 cap after exhausting the gas. That’s not going to happn, though; because when I took off the CO2 cap to install 2 fresh CO2 cartridges, I noticed the o-ring was damaged pretty bad. So bad, in fact, that it might not work any longer. I switched it for a common black Buna o-ring of the same size and then charged the gun. At the end of this report, I’ll tell you how that works.
JSB Exact RS
When I tested the rifle at 10 meters, the best pellet was the JSB Exact RS dome, so that was the first pellet I tested this time. As I predicted after shimming the rear scope ring, the rifle was hitting too high at 25 yards. I had to drop it about 2-1/2 inches and move it to the right about three-quarters of an inch.
The first 10-shot group I fired measures 0.523 inches between centers. It’s nice and round, also. Remember, I’m using the 4x scope that came with the rifle, so the bullseyes looked pretty small at 25 yards. Also keep in mind that this shooting was done indoors, so wind is not a factor.
The first group looked so good through my spotting scope that I shot a second one with the same RS pellets. This time, 9 of the pellets went into 0.455-inches, but one shot opened the group to 0.688 inches. That wild shot was not a called flier; it just went astray.
This second group of JSB Exact RS pellets measures 0.688 inches between centers.
H&N Baracuda Match
The second-best pellet at 10 meters was the H&N Baracuda Match, so that was the next pellet I tried. Ten landed in a 0.625-inch group that’s open but fairly round at the same time. Looking through the scope, this group didn’t look very promising; but I see upon inspection that it isn’t much worse than the first 2 groups.
Air Arms Falcon
The final pellet of the day was the Air Arms Falcon dome, which is made by JSB. Sometimes, this pellet surprises me with stellar accuracy. This time, 10 pellets made a group that measured 0.56 inches between centers. It’s very close to the first group of JSB Exact RS pellets, which turned out to be the best group of the day.
The new o-ring
The new o-ring worked, but there was some leakage when I pierced the cartridges. The gas exhaust screw wasn’t the culprit this time — it was the o-ring that leaked. I suspect I selected a ring that is too thin for the job. When I removed the cap, I saw that this ring had also absorbed the gas and swollen quite large. I took a picture of it 5 minutes after taking it out of the gun and again after 45 minutes, so you can see the dramatic difference as the o-ring outgasses and shrinks back to normal.
There’s a lot to like about the Fusion air rifle. It certainly is accurate, and it fully delivers on the promise of quiet operation. There aren’t many other air rifles in this price range that can compete. Even the scope that comes with the rifle seems to be up to the task.
While today’s groups are not stunning, they’re all good. It’s interesting to note they’re all under three-quarters of an inch and some approach a half inch.
I do think the o-ring that comes with the rifle needs to be changed to something that doesn’t swell. And it would be nice if the trigger was more adjustable. But those are small points. If you’re looking for a fun plinker that’s both quiet and accurate, put this one on your list!

This report is getting long and perhaps a little confusing, so let me explain what I’m doing. We’ve been looking at the Air Arms TX200 Mark III underlever air rifle. I used my own TX for the first 6 parts of the report. In Part 7, I introduced a brand new TX that Pyramyd Air sent for me to test. Many of you were concerned that the rifle had changed somehow over the years since mine was made, and perhaps what’s shipped today isn’t the same rifle…so I agreed to test a new one for you. The first look at that rifle came in Part 7 of the report, and in Part 8 we looked at the velocity.
Today ,I’m going to show you the trigger in detail, describe how to adjust it and explain why I always say the TX trigger is an upgrade of the Rekord trigger that Weihrauch introduced back in the 1950s. To get to the trigger adjustments, the triggerguard must be removed. But today I’m going farther into the gun to show you the entire trigger assembly. That will help me explain how the trigger functions.
The stock needs to come off to get into the rifle, so I did that first. Just remove 2 forearm screws and 2 more triggerguard screws.
Once out of the stock, the action and trigger can be seen clearly.
Here you see the disassembly bolt (all the way to the lef). Turn it out, and the rifle comes apart. You can also see the 3 trigger adjustment screws. On the trigger blade are screws to adjust the first-stage length and adjust the sear contact area. Behind the trigger blade is an Allen screw that adjusts the trigger pull weight. Behind that is the threaded hole the rear triggerguard screw goes into.
If I were just adjusting the trigger I wouldn’t need to go even this far. Just remove the triggerguard and start by adjusting the trigger return spring tension. I found that was all I needed to do on the test rifle, as the first-stage length and sear contact area were right as they came from the factory. But you can adjust either of them or both.
To take the trigger unit out of the gun, I removed the disassembly bolt. As it turned, I pressed down on the entire barrelled action with the end cap resting on a soft cloth pad. When the bolt was free, the mainspring decompressed less than 2 inches.
When the trigger unit comes out of the rifle, it’s still pinned to the end cap and spring guide like this. Now, the trigger unit looks familiar to Rekord owners because the 2 pins that hold it to the end cap are visible.
Because I want to show you how this trigger works, I’m going to continue to disassemble the end cap. The 2 pins that hold the trigger unit in the cap are driven out. They are several times harder to remove than Weihrauch trigger pins. This unit is together very tight!
Once the trigger assembly is out, we can see how it differs from the Rekord.
The trigger assembly is similar to the Rekord — but also different. The box is riveted together instead of being a folded sheet metal structure. There’s an additional pin, forward of the trigger blade, and internally there are bearings where the Rekord parts just turn on pins.
So far, I’ve shown you the differences but not described how they work. For starters, the Air Arms trigger has adjustments for the first-stage pull and for the sear contact area, as well as for trigger-pull weight. The Rekord has the sear engagement adjustment and the pull weight adjustment but not the first-stage adjustment. But that isn’t what makes the Air Arms trigger better.
What makes the Air Arms trigger better is the presence of bearings instead of just pins. The parts are also more finely fitted, which has to be done during manufacture because there’s no money in the gun for costly hand-fitting. And the trigger isn’t the only place that’s different. The piston is also different.
The TX200 has what I will call a circular piston. All pistons are circular, of course, but most of them are held from rotating by the cocking shoe. Because of that, the piston can have a hook that’s engaged by the trigger when the gun’s cocked. That’s how the Weihrauch rifles that use the Rekord trigger are made. But what if the piston was free to rotate on its axis?
Blog reader RidgeRunner asked how the TX piston was cocked by the sliding compression chamber. The answer is that the chamber pushes the piston back until the trigger catches it. The piston rod is so long that it can be caught by the trigger while the piston is still inside the compression chamber.
When the gun is cocked, the piston rod comes back and pushes the trigger parts into lockup. As they lock up, a hook catches the rear of the piston rod and holds it until the sear releases it.
The ability of the piston to turn on its long axis while being supported front and rear by bearings adds smoothness to the powerplant without sacrificing power. A centrally located air transfer port that’s centered on the piston boosts the air scavenging efficiency and therefore the available power. The TX200 Mark III is giving all the power it can from a powerplant that’s still smooth and easily cocked.
How is the trigger after adjustment?
Before I adjusted the trigger, it released crisply at 1 lb., 12 oz., which is 28 oz. All I adjusted was the trigger return spring tension and now the trigger breaks cleanly at 12 ounces. So the adjustment dropped one entire pound. And, yet, the sear still has the same contact area, so it’s just as safe as before.
A good tuner can adjust a Rekord just as light, but the sear contact area won’t be as great as it is at 3 lbs. The Air Arms trigger allows for this adjustment without sacrificing any safety. That’s what I meant by the TX trigger being more finely adjustable that a Rekord.
By the way, the work done here, including taking the pictures, took a total of 30 minutes.
