Length of pull
Before we begin, I want to say a word about the length of pull you get with this adapter. I gave the range of lengths in Part 1 as 14-1/8 inches to 17-1/8 inches, and that turned off many readers. In terms of conventional stocks, that pull range is very long! But Dave Rensing, who invented this adapter, made it for his 8-year-old son and his 7-year-old daughter. The son uses it conventionally, but the daughter collapses the stock past the first detent so it’s even shorter. Fully collapsed, the pull length measures exactly 14 inches but feels like 11 inches.
The AR adjustable stock is not very ergonomic. It stretches and contracts okay, but it doesn’t move in the other directions. It’s a one-size fits none kind of deal — at least from a rifle marksmanship standpoint. While it works very well for fast maneuvering and climbing in and out of tight places, your body has to adapt a lot to make it work.
On the other hand, when the R.A.I. adapter is added to it, the stock becomes almost universal! You can adjust the positions of the comb and the angles of the buttstock through a wide range of attitudes and make it fit almost anyone — young or old. I found when shooting from the bench that even the 15-1/8-inch pull I had initially set up was too short. I had to move the stock back until the pull was 15-7/8-inches before it felt natural again. However, in the offhand position, the 15-1/8-inch pull is the right one. That demonstrates why the adjustable stock works so well on this pistol! You can adjust it to whatever you need in the blink of an eye.
I discovered why this is. The AR adjustable stock has no width. The narrow tube is where your cheek rests, so your eye is closer to the centerline of the pistol than it would be with a conventional stock. The stock also does not drop at the butt, so your head thrusts forward farther than it might with a conventional stock. Instead of sticking up to rest on the cheekpiece, your head tilts forward, along the straight tube. Hence, 14 inches feels more like 11 inches. The Marauder’s pistol grip and close trigger enhance this feeling.
Scope and mounts
I wanted to test the pistol with a really good scope; and the last time I tested the Marauder I used a CenterPoint 3-12X44 compact scope. Leapers was making CenterPoint scopes back then, so this time I attached a UTG 3-12X44 compact scope. My scope is older than the one I linked to, but the optics and overall size are the same. Not only does this scope fit the carbine very well, it gives a crystal clear sight picture that makes aiming so easy.
I needed to get the scope high off the receiver because the Marauder pistol has a circular 8-shot magazine that sticks up above the receiver top. You can see it in the above photo. Also, the stock’s straight line puts my head higher than it would normally be. So, high scope rings are in order. I selected a pair of BKL 30mm high rings that have a single-screw top strap. The Marauder pistol doesn’t recoil, so these rings can be made thinner and still be strong enough to hold this scope. Once they were mounted, I noted they brought the scope’s exit pupil directly to my eye, making them the perfect height.
Testing the Marauder carbine
I tested this Marauder pistol extensively, back in 2010/2011. I already knew the right fill pressure (2,900 psi), the best pellet (.22-caliber Beeman Kodiak) and the effective number of shots per fill (32). Since it has an 8-shot magazine, I shot 8-shot groups instead of 10.
Sight-in went quick, and then I backed up to 25 yards and started shooting. The first group of Kodiaks was the second-best of the session, putting 8 into 0.554 inches. Looking back at the tests I did years ago, I wasn’t shooting as well on this day as I did back then. I shot a total of six 8-shot groups, and the largest one was 0.607 inches, while the smallest was 0.504 inches between centers.
While these groups are okay, they aren’t as small as the groups I shot previously. I don’t think it was me or the gun. In this case, I think it was the pellet. I used a different tin of Kodiaks in 2010, and they grouped much tighter in this pistol than these did. The best group back then was 0.405 inches between centers. Maybe they had larger heads, or maybe they were just different in some unquantifiable way.
I tried a number of different pellets in the Marauder pistol, but none of them did very well. JSBs of various weights, which I thought would do well, sprayed all over the place. I know from testing the gun that it wants a fat pellet, and the Kodiak is a good one for that. It’s slow, at an average 584 f.p.s., but even at that it produces about 16 foot-pounds of muzzle energy. That’s pretty good for an air pistol! Certainly enough for some hunting and pest elimination.
The rest of the test
I plan to take this pistol to the 50-yard range, so you’ll see the results of that. But I don’t think that’s quite the right way to test the R.A.I. adapter and adjustable stock. We already know how well the pistol performs. Now, we want the focus to be on the adapter and the stock.
Maybe I can put the gun in the hands of some other shooters and see how well it fits them. Perhaps, that’s the best way to evaluate this item. I don’t know, but I guess we’ll see.

Happy New year! I thought I’d review the best products I got to test last year. Some will be new, but others have been around a long time — I just got around to testing them.
Benjamin Marauder pistol
Back in January, when I was pouting about missing the SHOT Show, I had the opportunity to test the Benjamin Marauder PCP pistol. Actually, the test began in 2010 and extended into 2011, but it was such a good test that the pistol has to make it into this report.
I even did an extra accuracy test because for the first one I mounted an old Leapers 6×32 scope that didn’t seem to give the pistol a chance to perform up to its capability. When I substituted a CenterPoint 3-12x44AO compact scope in the last test, the pistol showed what it can do.
The Marauder pistol is a .22 caliber with all the accuracy you could hope for. The power is great for this size airgun, and I strongly recommend attaching the standard shoulder stock extension that comes with the gun.
The next great product of 2011 was the Beretta model 92FS air pistol with wood grips. I completed the test on this one in March. I was so impressed that I thought for a long time that Edith and I needed to get the firearm to go with it. In the end, we returned it because you just can’t keep them all; but while I had it, I thought it was a wonderful air pistol.
Hawke Sport Optics 4.5-14x42AO Tactical Sidewinder rifle scope
This one is not an airgun, but I would be remiss if I didn’t tell you about the finest rifle scope I’ve ever tested — the Hawke Sport Optics 4.5-14x42AO Tactical Sidewinder rifle scope. I’ve owned several Leupolds and looked through other premium scopes, but this Hawke has them all beat.
What’s so good about this scope? The clarity. It’s even clearer than my Unertl 6x that used to be a standard for target shooters. At 14x, it’s clearer than other scopes are at 32x. You have to see it to understand how that could be possible, but it is.
It’s very costly, though with the clarity it surpasses others of greater price. It’s the best I’ve ever seen.
Crosman Silhouette pistol
The Crosman Silhouette PCP air pistol is another pistol that made my list. I’d tested it the year before, but this one had some improvements, the most notable of which was the trigger.
The power is great, in the high 400s with medium-weight .177 pellets, but the number of shots on a fill reached 75, which is even more phenomenal. Crosman really did their homework on this pistol — refusing to let it alone after the initial offering. The result is that they launched an even better model in 2011 that will have airgunners talking for a long time.
Walther Lever Action rifle
Walther already had a good lever-action air rifle, but last year they modernized it to accept the 88-gram CO2 cartridges, and the new Walther Lever Action Rifle is even better than before! I liked it so much that I did a special 4-part review on the gun and showed you accuracy you didn’t expect to see from this kind of airgun.
This rifle is pricy, but you get what you pay for. It’s slick, accurate and reliable. If you want a good lever-action pellet rifle it’s the only game in town. (My test featured the nickel version, but Pyramyd Air no longer sells it…but the blued version is still available.)
Crosman M4-177 air rifle
I would be remiss if I didn’t rave about the new Crosman M4-177 multi-pump air rifle. I liked mine so much I bought it! Does that tell you anything?
The gun is realistic, accurate and well-made. I bought one of the early guns that were mismarked, but Crosman begins shipping guns with the correct marking this month. I don’t know if Pyramyd Air has any of the mismarked ones left. However, don’t let that stop you — this is an airgun we can all enjoy.
MTM Predator Shooting table and Predator shooting rest
I use both the MTM Predator shooting table and the Predator shooting rest for almost all of my tests, if that tells you anything. But they’ve just been added to the Pyramyd Air product list and are now available to all of you. So, I included them in the 2011 list, even though I’ve had mine for several years. Both products let you make a firing line wherever you are, and that’s a necessity for someone who shoots a lot. I take mine to the rifle range and use the table in preference to the concrete tables on the range.
Dan Wesson BB revolver
We ended the year on a high note with the Dan Wesson BB revolver. When I reported on this novel new revolver, I said I was impressed by the realism they packed into the design. Twenty years ago, you just couldn’t get this level of realism in an airgun.
The one thing I failed to note in my report is the quirky way the safety works. Of course, a safety on a revolver is about as common as a unicorn horn; but if you have one, it ought to work right. This one doesn’t. You can put it on when the hammer is down and the action will be locked; but if the hammer is cocked, the safety does nothing at all. That’s dangerous, because there are new shooters who haven’t been properly trained and will test every safety in an unsafe way. This one will fire if they do.
Still, the gun is powerful, gets lots of shots and is quite accurate for a BB pistol. It’s also all metal. I don’t know what more you could ask for.
I reviewed many other airguns in 2011, including a host of vintage models that I won’t report in this list. These are the ones that stood out and caught my interest. You may have others, and now it’s your turn to comment.

This is the test I promised at the end of Part 3 of the .22-caliber Benjamin Marauder air pistol report back in December. You’ll remember that I didn’t think the scope I used for accuracy testing in Part 3 was doing all it could for the gun. I said I would try it again with the 30mm Centerpoint scope Crosman had sent with the gun, once I had a set of rings to mount it.
If you’re just learning about the Benjamin Marauder pistol for the first time with this report, you need to know that this pistol has taken the airgun world by storm. Just as the Benjamin Marauder rifle holds its own with European PCPs costing two to three times as much, the Marauder pistol does the same when compared to the high-priced PCPs coming from the same European companies. It’s a red-hot seller that offers unprecedented power and accuracy at an affordable price.
It has a choked Crosman barrel that stands equal to tubes from Anschütz and Lothar Walther. The reputation hasn’t been built yet, but the performance is undeniable. The trigger is very sweet and fully adjustable, and of course the pistol is shrouded. When fired, it sounds like a Daisy Red Ryder instead of the 15 foot-pound hunting airgun that it is.
I wasn’t satisfied that I’d seen all the accuracy the pistol had to offer in the last accuracy test, so this additional test was added to give us a second look. What I learned this time was remarkable and worthy of note, but I’ll get to that later.
For this test, I mounted Centerpoint’s 3-12×44 Power Class scope with mil-dot reticle and sidewheel AO in a set of two-piece Centerpoint 30mm high rings that Crosman provided. The high rings raised the scope up so high that I had to rest my chin on the comb of the detachable shoulder stock to see a clear image. If this were my pistol I would attach about an inch of firm foam padding to the top of the shoulder stock comb to bring my eye comfortably up to the right height.
This scope is sufficiently clear and bright enough that it enhanced the sight picture rather than detracting like the last scope did. Although the reticle lines are not thin, I was able to see the intersection of both the horizontal and vertical lines clearly inside the 10-ring of the bull, so aiming was more precise than it had been during the test in Part 3.
Which pellet to use?
Normally, when testing the accuracy of any airgun, I select four to six different pellets that I think will work, given the power and potential accuracy of the test gun. Then, we’ll see how they actually do on the range. Picking pellets for accuracy testing is fairly straightforward and based on the past performance of those pellets in similar guns. But not this time. I tried five different types of .22 caliber pellets, in addition to two other pellets that were used in Part 3 (Beeman Kodiaks were reused in this test because they did so well the first time around). However, nothing I tried wanted to group — except the Kodiaks. Kodiaks grouped so well that the pistol is an undeniable tackdriver. But, I’m getting ahead of myself.
Unfortunately, I didn’t pick Kodiaks from the start to sight-in the new scope, therefore I stumbled around with two other pellets for quite a while before realizing what was happening. They were RWS Superdomes and 15.9-grain JSB Exact domes. Both gave mediocre groups of about one inch at 25 yards in the test pistol, which made sighting-in very difficult. Then, I just gave up and defaulted to the Kodiaks that had done so well in the last accuracy test I delivered in Part 3. That’s when the gun started to perform.
In fact, the first “group” of Kodiaks was just for kicks to see where 8 pellets would land. Eight instead of 10, because that’s how many the magazine holds.
After that, I shot group after group, and they were all similar. After several tight groups had built up my confidence in the gun, I was reminded of my old Hakim rifle that used to lob them into a similar round group at 10 meters. I would get so mesmerized by how accurate that rifle was that I couldn’t stop shooting. The sight of each new tight group when I went downrange to change targets was a turn-on. In the case of the Marauder pistol, I could watch through the scope as shot after shot went into the same ragged hole, only not at 10 meters but 25 yards. Thinking about my old Hakim also reminded me that the most accurate pellet in that rifle was the RWS Superpoint, which is now called the Superpoint Extra.
So, I got a tin of those and tried them in the pistol. Wrong! The groups opened up to almost one inch once more. So I wondered whether the heavy 18.1-grain JSB Exact Jumbos would perform more like the Kodiaks. After all, they are within a couple grains of the Kodiak’s weight and they are made by JSB. But I might as well have been shooting a shotgun, for all the good they did. No, this pistol wants to shoot Beeman Kodiaks, and nothing else!
I know this photo looks fishy, like I’m hiding a pellet hole under the coin, but I’m not. It’s just difficult to position a dime next to a target on a scanner. This group of eight Kodiaks measures 0.529 inches between centers. The top and bottom holes have closed, making the group appear smaller than it really is. This group is about the average size of all the Kodiak groups I fired.
Then, I had a thought. What about those new copperplated Kodiaks? Would they do just as well as the regular Kodiaks? If I didn’t try them, someone would bring it to my attention. I didn’t think the copperplated ones would perform the same as pure lead Kodiaks, but the only way to know for sure is to shoot them. I loaded a magazine and gave them a try. Much to my surprise, they did just as good as the all-lead Kodiaks.
That’s my report on the Marauder pistol. Some will read it and grouse about the pistol not doing well with a wide range of pellets, but the black powder cartridge shooter in me says that as long as there’s one bullet or pellet that shines, the gun is alright. Once I find that one best pellet, I never mess with the others anyway. In the test pistol, Beeman Kodiak pellets are the clear winner. I would continue to try other pellets from time to time, but Kodiaks would remain my standard ammo until displaced by something even better.
The Benjamin Marauder pistol is every bit as stunning as the Marauder rifle, by reason of accuracy, power, trigger and quiet operation. As long as you use the shoulder stock that comes with the gun and as long as you mount a good-quality scope, this pistol is a real shooter. If you’re looking for a stealthy hunting air pistol, give this one serious consideration.
