Yesterday, I told you that today’s test was coming; but because I needed to mount a scope for this test, I was prompted to also test the UTG 3/8″ dovetail-to-Weaver/Picatinny rail adapter. There was some interest in this adapter; so I’ll continue to test it with other airguns so we get a good look at the performance. Today, I want to do Part 4 on the Crosman 2100B multi-pump that I promised back in March.
I reread Part 3 of this report to see which pellet(s) did well at 10 meters. From what I see, only 7.9-grain Crosman Premiers did well in that test, so I added a couple pellets I had not tried before to today’s test.
The scope I used is an Osprey 2.5-10×42 that has its parallax fixed at 100 yards. It’s a firearm scope, pure and simple. At full magnification, the target was fuzzy, so I set it to about 5.5x for this test. It has a duplex reticle with mil-dots on the vertical reticle, which is about medium thickness. The optics are very clear, and I think the gun got all the help it needed from this scope.
For the 10-meter test, I pumped the rifle 5 times for every shot. Today, I’ll be shooting 25 yards. Now that it has a scope mounted, pumping is more difficult because I cannot hold the gun at the optimum place, which is on top of the receiver. The scope is in the way, and don’t you dare try to pump the rifle while holding onto the scope! Your hand has to hold the gun farther back, which winds up being the pistol grip of the stock. That isn’t the best leverage to pump the rifle, but fortunately the 2100B has a short, easy pump stroke.
For today’s 25-yard test, I pumped the rifle 6 times for every shot. My thought was to shoot the rifle 5 shots with each pellet and see if it was accurate enough with that pellet to warrant the work of shooting the second 5 shots. This would also tell me whether the shots were walking because the bore needed to be seasoned with each new pellet. As it turned out, though, all three pellets were worth the effort to shoot a full 10-shot group, so that’s what you’ll see.
Crosman Premier lites
The first pellet I tried was the 7.9-grain Crosman Premier dome. The first 5 shots seemed to group okay — about what I expected from the earlier results at 10 meters — so I just kept on shooting and finished the 10-shot group. Ten shots landed in a group measuring 0.809 inches between centers. The group is a little wider than it is tall, but you’ll notice that 9 of the 10 shots are actually in a group that is fairly round.
This was better accuracy than I expected, based on the results of the 10-meter test. The group size there was 10 Premiers in a 0.539-inch group; and, at over twice the distance, the group only opened another three-tenths of an inch. I think that demonstrates how much greater accuracy is provided by a good optical sight.
The pace of shooting is slower
One thing about shooting a multi-pump is that everything slows down. It takes a while to make each shot ready, which is similar in concept to shooting a muzzleloading rifle that has to be loaded separately with powder and ball. That slower pace forces the shooter to concentrate more on what he’s doing — or at least that’s how it affects me. That’s why I like single-shot rifles so much — for what they bring out in me.
The second pellet I tried was the RWS Superdome. This 8.3-grain domed pellet is one I don’t try too often — for no particular reason. It’s made from pure lead and has a relatively thin skirt that takes the rifling very well. I really didn’t know what to expect from it, but it’s different enough than a Premier lite that I wanted to see how it might do.
Ten Superdomes made a rather open group that measures exactly the same as the group of Premiers — 0.809 inches between centers. It looks like a larger group, and there’s undoubtedly some error in the measurement of both groups, but I cannot discern any difference between them with the dial calipers.
H&N Baracuda Greens
The last pellet I tried was an afterthought, based on the success of the other day. H&N Baracuda Greens made such a great initial showing that I thought I would include them in this test, just for fun. Boy, am I glad I did!
I was unable to see the pellets that landed inside the black bulls because of the parallax setting of the scope, so it wasn’t until I walked downrange to retrieve the target that I saw what the Baracuda Greens had done. Ten went into a group that measures 0.48 inches between centers! Not only is this the best group of this test, it actually outshot the M4-177 I tested at the end of 2011. That’s Crosman’s other hot, low-cost multi-pump, so don’t get it confused with the MAR177 PCP. That kind of performance says a lot about this air rifle and the accuracy that it offers for very little money.
This will be the last time I look at the 2100B, but it’s been an interesting test. After Part 3, I didn’t think the gun had much more to show us — but this final accuracy test changes everything.
We’ve looked at a fine multi-pump air rifle in addition to the UTG scope ring adapters that let you use Weaver rings on an 11mm airgun dovetail. They proved very easy to install and worked exactly as advertised in this test.
And the Baracuda Green gets another pat on the back. This is a pellet worth considering when you search for the best ammo.
All things considered, I would say this was a fine end to the test of a really great and also inexpensive air rifle!

Recently, a reader asked me when I was going to write the part 4 I promised for the Crosman 2100B multi-pump rifle. I did Part 3 in March, and to be honest, I’d forgotten that a part 4 was promised.
Part 4 is going to be a 25-yard accuracy test with a scoped rifle, because I felt the 2100B deserves it from the performance it delivered in the 10-meter test. Fortunately, the rifle is still available to me, so I planned on doing my report today. All I had to do was install a scope on the scope rails and….
[Let's pretend] the only scope available to me is already installed in Weaver scope rings. Whatever will I do?
Well, before 2012, I would suck wind. I’d sit on the curb and cry my eyes out, because I had the wrong scope mounts for this rifle. Fortunately, we now live in a world where the UTG 3/8″ dovetail-to-Weaver/Picatinny rail adapter is available. And I have one! Oh, happy day! The test will proceed as planned!
Readers with better memories than mine will recall that I showed you this adapter back in the SHOT Show report, Part 2 this year. You may have wondered why I made such a fuss in that report over two confusing pieces of metal I held in my hand. Today, you’ll find out why.
This is a UTG product. UTG stands for Under The Gun, one of Leapers’ trademarks. So, you’ve already learned something, haven’t you? This adapter attaches to the base of a Weaver (or Picatinny) scope mount and converts it the mount to a 3/8-inch dovetail. Now, 3/8-inch — the rimfire dovetail width — is so close to 11mm — the airgun dovetail width — that it also works for most airguns. I say “most” because there may be a few very wide 11mm dovetail scope bases that are too wide to accept this adapter. I don’t know that — I’m just saying that there might be.
The bottom line is that this adapter should work for all rimfires that have grooved receivers as well as for most airguns that have an 11mm dovetail scope base. And please know two additional things – - first, that 11mm is a nominal width and in reality the dovetails are from about 9.5mm to as much as 14mm wide; and second, that Weaver and Picatinny bases ARE ALSO DOVETAILS! It is completely incorrect to refer to an 11mm dovetail as just a “dovetail,” because there are other different kinds of scope bases that are also dovetails. There — you’ve learned something else!
The UTG 3/8-inch dovetail-to-Weaver/Picatinny adapter comes as two identical pieces. Both piece have a vertical scope stop screw that can be removed for guns that don’t need it. This photo shows both sides of the adapter.
Those four pictures show you how these scope rings and bases work. You can see that the Weaver clamp will not fit an 11mm dovetail or a 3/8-inch dovetail that would be found on an air rifle or a rimfire. So, a Weaver mount will not attach to those guns — until now. The UTG adapter converts the Weaver scope ring base to an 11mm base.
The UTG adapter has been inserted into a Weaver ring base. The base will now fit an 11mm dovetail. Because the 2100B is a pneumatic rifle that does not recoil, I removed both scope stop screws before installing the adapter.
Here you see the adapter in the Weaver base from a side view. Notice that the adapter is only a few hundredths of an inch taller than the original base when installed. It makes no practical difference to the scope’s height over the bore. The amount the adapter overhangs the ring base at either end is meaningless, as the adapter is locked in position by the Weaver cross key. As long as the adapters fit the gun you mount them on, you’re good to go.
Is this adapter useful?
If you need to mount Weaver rings to a gun that has either 3/8-inch or 11mm dovetails, this adapter is the only way to go. I don’t know of another way to do it. Some of you are probably saying to yourselves, “Why wouldn’t I just buy 11mm rings and be done with it?” Well, that’s certainly what you had to do before this adapter came along.
But some of you have a favorite firearm scope that you like a lot, and maybe you have it installed perfectly in a nice sturdy set of Weaver rings. You guys understand the benefit of an adapter like this, because it allows you to use something you’re comfortable with. It installs or removes in seconds, allowing you to use that scope wherever you choose. And, because the adapter comes with its own built-in scope-stop pins, it fits almost every airgun you can name.
I will mount this scope on the Crosman 2100B next and conduct the 25-yard accuracy test I promised many months ago.

This is the second of my reports on the 2012 SHOT Show. There will certainly be at least one more after this, and perhaps even more, as there’s simply too much new information to pack into a single report.
The state of the airgun industry in 2012
Before I get to some specifics, I want to make a general observation. This year’s SHOT Show was different for me in a major way, because I saw for the first time that firearms shooters are beginning to understand airguns as never before. In the past, I always had to start my explanations with the cooling of the earth’s crust and then progress through the age of the dinosaurs because each firearms person I talked to thought of airguns as either toys or BB guns. This year, a lot of them were clued-in on what’s happening. They weren’t surprised by the accuracy we get, and they knew about big bores. A lot of them had some airgun experience and more than a few asked me the same kind of questions that I get from long-time readers of this blog.
That tells me the day of the airgun has finally dawned in the U.S. Instead of 25,000 to 50,000 active shooters (at best!), we will now see an influx from over 5 million active firearm shooters who are ready to augment their shooting experience with airguns. I’m already getting calls and emails from state departments of wildlife resources, asking about the issues of incorporating airguns into their hunting seasons.
It has been a long haul to get to this point, but we’re now seeing the start of the harvest of all the work that’s been done over the past 40 years — starting with Robert Beeman in the early 1970s. The job is now to manage this growth and provide useful information to the tens of thousands of new airgunners who are flooding in the doors.
Let me reflect on how the industry seems to be reacting to this trend. Some companies have been on board for many years and are poised to ride the new tidal wave of business as far as they can. Other companies are aware that airguns are very hot, but they’re foundering, trying to understand them. Let me say right now that it’s not as easy as you think!
The readers of this blog are among the most clued-in airgunners in the world. But they’re unique, and they do not represent the true market. The demographic of a new airgunner is a man (usually) in his late 20s to late 40s who is most likely a fan of AR-type rifles and Glock-type pistols. He wants repeaters, semiautos and he thinks that a five-shot group is the gold standard of any gun. Velocity impresses him, and he isn’t comfortable with the term kinetic energy.
Things like good triggers and good sights are not an issue with this customer until he experiences bad ones. His ARs have decent triggers off the rack, and he can choose from many drop-in triggers that are much better. When he encounters a spring-piston gun with a horrible trigger that cannot be easily modified, he’s surprised.
He does not use the artillery hold, and he equates all airguns to be alike in terms of performance. When he learns about precharged guns, he’s put off by the additional equipment he must buy. Spring-piston guns seem the best to him for their simple operation, and he doesn’t appreciate the fact that they’re also the most difficult airguns to shoot well.
That’s the customer who’s coming to airguns today, so that’s the person airgun manufacturers have to deal with. If you have wondered why many of the new airguns are what they are — this new-customer profile is the reason.
Okay, I’ve talked about those companies that get it and those that are struggling to understand. There’s one more type of company out there. I like to call them the “gloom and doom company” or the “zero sum company.” They’re firmly entrenched in the 1970s and cannot take advantage of this new windfall of business. They either fired their engineers years ago or they let them all retire, and now they couldn’t build a new airgun to save their lives. As far as they’re concerned, there are only 25,000 airgunners in the United States and it’s the NRA’s responsibility to identify and train them so these companies can sell them some guns.
They think of marketing in 1950′s terms, when a simple paint job and some sheet metal was enough to create a new product. Their “secret” business plan is to buy guns made by other manufacturers and have their name put on. If you’re a collector, better buy up the guns these guys sell because in 10 years their name will be a memory.
That’s enough of the big picture. Let’s see some more products.
More from Crosman
Many of you saw the list of new Crosman products Kevin posted last week, so the few that I show here are by no means all there is, but they’re the highlights. Crosman had about half the new airgun products at the entire SHOT Show.
New tan M4-177 and carry handle
The M4-177 multi-pump that I recently tested for you is going to be very popular this year. Crosman is also offering it as an M4-177 Tactical air rifle with a new carry handle that replaces the rear sight for improved sighting options. I think this gun will be in their lineup for many years to come.
I mentioned to Crosman’s Ed Schultz that this rifle looks like the A.I.R.-17 of the 1990s, but done better. He said he always wanted to update that design, and that is exactly what this is. So, what he said next came as no great surprise.
I shared my thoughts on a 2260 made as a multi-pump in .25 caliber, and Ed told me that was how the rifle was originally created (not in .25, however). The CO2 version was an afterthought that got put into production, while the multi-pump version languished in the Crosman morgue. I told him that I thought the time was ripe to bring it back as an upscale hunting rifle, and he seemed to agree. We can only hope.
Carbon fiber tank
As Crosman extends their capability into PCP guns, they know shooters are always looking for better options for their air supply. Besides the new butterfly hand pump I showed you last time, they’ll also be adding a long summer-sausage black carbon fiber tank with increased capacity over their current tanks. This is a 300-bar tank that has 342 cubic-inch capacity. It comes in a black nylon carrying case with sling for field transport.
More air for you! New Benjamin carbon fiber tank will help you take your PCPs further afield.
Benjamin Nitro Piston breakbarrel pistol
The Benjamin NP breakbarrel pistol certainly has people talking on the internet. This is the first commercial gas spring application in a pistol, I believe. The most distinctive feature is a cocking aid that can either be detached or left in place while shooting. That reminds us that this pistol is going to be hard to cock, but I’ll test one for you so we’ll all know just how hard.
New Benjamin Trail NP pistol is a breakbarrel with a gas spring. The cocking aid can be detached or left in place while shooting.
Crosman 1720T PCP pistol
Everybody was ready to jump down Crosman’s throat for creating the 1720T PCP pistol. They wondered with the .22-caliber Marauder pistol and the .177-caliber Silhouette PCP pistol already selling, why was this one needed? As Ed Schultz explained it to me — this one is for field target. It’s a .177 (naturally) that produces just under 12 foot-pounds through a shrouded Lother Walther barrel. It can be used for hunting, but field target was its primary purpose. They worried about the shot count with the Silhouette; but with this one, power was the criterion. Look for about 800 f.p.s. with a 7.9-grain Premier. And the trigger is the same as the Marauder, so excellent operation there.
Crosman MAR 177 PCP conversion
The Crosman MAR-177 PCP conversion is another new product that has a lot of people talking. This AR-15 upper converts your .223 semiauto into a .177 PCP repeating target rifle. Because it’s on an AR platform, almost everybody expects it to be semiautomatic — including those who should know better. This rifle is a bolt action that cocks and loads via a short pull on the charging handle.
This conversion is an Olympic-grade target rifle for a new official sport that Scott Pilkington and others have been promoting for several years. It will take the U.S. battle rifle back into the ranks of target shooting. However, the look of the gun has many shooters totally confused. I was even asked at the show if I thought Crosman should have come out with an “everyman’s” version of the gun first. That would be like asking whether Feinwerkbau missed the boat by not first making their 700 target rifle in a $300 version for casual plinkers.
Crosman TT BB pistol
It’s all-metal and a good copy of the Tokarev pistol. The weight is good and the gun feels just right. This will be one to test as soon as possible.
Crosman’s TT Tokarev BB pistol is realistic and looks like fun.
Benjamin MAV 77 Underlever
The Benjamin MAV 77 underlever rifle is going to force Crosman to recognize spring-piston air rifles instead of just calling them all breakbarrels. This is the TX-200 copy from BAM that was once sold by Pyramyd Air. When the quality dropped off, it was discontinued. Hopefully, Crosman will watch the quality on this one.
They didn’t have a firm retail price yet, but hopefully it’ll be significantly under the TX. Otherwise, why buy it? I may test one for you, but I already know that BAM can make a great rifle when they want to. I think it all comes down to price.
Benjamin MAV-77 is an underlever spring-piston rifle that looks and, hopefully, performs like an Air Arms TX-200.
The Crosman TR-77 is a conventional breakbarrel spring-piston rifle in an unconventional stock. It’s different enough that I want to test one for you. It appears to be a lower-powered rifle that probably sells at a bargain price because it’s branded under the Crosman banner rather than Benjamin. Mac photographed one in a sand-colored stock for you.
Crosman TR-77 breakbarrel in a sand-colored stock also comes in black.
There was a lot more at Crosman that I could have mentioned, but now let’s go over to the Leapers booth.
I’ve watched Leapers grow from a relatively small company back in 1998 to a major player — blasting past older, entrenched companies as they grew. This year, they were playing a video about the company on a continuous loop in their booth. I was impressed to see their plant in Livonia, Michigan, where they build airsoft guns, tactical mounts, accessories and scopes right here in the U.S. The plant is filled with many CNC machining centers and testing facilities to keep close watch over their products during development.
Leapers owner David Ding told me he wants to get control over the production process so he can assure the quality of all of his products. In keeping with that goal, I was shown the new scope line for 2012 that now offers locking target knobs on all of the upscale models. Many of them feature etched glass reticles that are amazingly crisp and sharp.
Mac was impressed by the reticle on the new 3-9x Bug Buster scope. He urged me to look through it; and when I did, I saw that the reticle is now fine and sharp — not the heavy black lines of the past.
David Ding shows me the new 3-9x Bug Buster scope (not out yet), with target knobs and a finer reticle.
But scopes were just the beginning at Leapers. Next, I was shown the whole line of tactical flashlights and lasers, including some mini lasers I will test on my M1911A1 for you. These are all made in the U.S. now and have more rugged internals, adjustments and optics than similar products from the Orient.
UTG 555 Long Range Light
One item I hope Pyramyd Air will consider stocking is a fantastic 500-lumen tactical light for law enforcement. It can be mounted on a rifle, handheld or even mounted on a bike! It comes with rechargeable lithium batteries and a smart charger…and believe me when I tell you it turns night into day!
The UTG Long Range light can go on your rifle, held in the hand or even mounted to your bike! The rechargeable lithium-ion battery pack will keep it shining at 500 lumens for 1.5 hours.
Fast Action Gun bag
Not all Leapers products are for airguns. They also make tactical and law enforcvement gear that rivals spec-built equipment but sells at a fraction the cost. As a result, many of their customers are ordering straight from the front lines of combat and from law enforcement agencies all over the country to get the products that their own supply lines cannot or will not furnish.
One of their latest developments is a Fast Action Gun bag that lets the wearer walk in public with a substantial firearm hidden from view. A quick pull of a strap, and the bag opens to reveal the weapon inside.
Leapers owner Tina Ding models their new Fast Action Gun bag. Here, it’s concealed; but she’s just pulled it over her shoulder from her back, where it looks like a tennis bag.
And in less than a second, the bag is open, giving instant access to the tactical shotgun or submachine gun inside.
Leapers has an entirely new range of quick-disconnect scope mounts coming this year, but there’s another innovation that I think you’ll find even more impressive. It’s an adapter that snaps into a Picatinny scope mount base, turning it into an 11mm dovetail. So, your conventional air rifle will now also accept Leapers Picatinny scope mounts with this adapter.
11mm-dovetail-to-Picatinny adapter is small and doesn’t raise the mount at all! This will be one to test!
Leapers is still the company to watch because the owners want to build a lasting corporation here in the U.S. They’re poised to move to the next level of quality in their optics, which gives me a lot of hope for the future — they’ve always been receptive to the needs of airgunners.
Whew! That’s a lot of products, and there are still many more to show. As I said in the beginning, there will be at least another report.
