You know, Babe Ruth was the home run king of his era. But he was also the strikeout king. Sometimes when you swing for the fence, you get fanned by the pitcher. I’ve done that a couple of times in recent reports.
The AirForce Escape SS has a 12-inch barrel. I said it was an 18-inch barrel, but several of you clever guys spotted why that could not be. And, while I was starting to redden from embarrassment in the AirForce booth, John McCaslin also took the opportunity to inform me that what I wrote about the Escape valve is also incorrect. It isn’t different than the TalonP valve — it is identical. So, gather a crowd and paint me red…I goofed!
The Escape has a 24-inch barrel, the Escape Ultra Light has an 18-inch barrel and the Escape SS has a 12-inch barrel. All 3 rifles come in either .22 or .25 calibers and no others.
The $100 PCP
I’m happy to report that Crosman is taking the $100 PCP project seriously. They will look into the possibility of making such an air rifle, but that doesn’t mean they have made any decisions to proceed. A lot of things must be taken into consideration beyond the fact that it might be possible. Don’t any of you start a clock on this! I’ll continue to test the rifle I have, and we’ll leave it at that.
Mike Mellick (Mike in Iowa) did come to Las Vegas, and we had a meeting. He showed me 2 examples of the rifles he’s currently selling, and we talked about my testing one for a feature article in Shotgun News. I plan to present the entire $100 PCP project in that article, which I think will be in the July 2014 color issue.
Okay. On to the new stuff.
Leapers is going to introduce an upgraded line of optics later this year that they’ll call the T8 line. They’re trying to offer optics as clear and sharp as those currently being sold for tactical use by Law Enforcement. They want to give $2000 worth of value for something in the $200 price range.
The first scope will be a 1-8X that fits the tactical scenario very well. If you’re in the CQB team, you run your scope on 1X and have a wide field of view and rapid acquisition. If you’re in the overwatch team, you’re running 3-4X and cover the door-breakers. The snipers sit on the high ground at 8X, watching everything.
I looked through a prototype scope, and it was clear as a bell, but the development is not quite finished. After it’s announced later this year, they’ll move ahead on a 2-16X scope to compliment the first one.
Leapers T8 scope line will offer upgraded optics.
I saw many products at Leapers this year, but the one that surprised me the most was the little peep sight they developed for a number of firearms. It’s so small, yet it adjusts in both directions. I asked if it could be made for airguns because then people wouldn’t have to root out the sides of their wood stocks to make room for the elevation slide — not that I’ve ever done that!
This peep sight is made to fit Weaver bases, but imagine what you could do with this on an airgun!
I saw the new field target rifle being offered by Air Arms. The FTP 900 is a purpose-built target rifle suited to knocking down those pesky steel targets. Short for Field Target Professional, the FTP replaces the EV2, their longtime field target competition rifle. It’s loaded with features. But to sum it up, this rifle is adjustable! It’s completely ergonomic, so it can be adjusted to fit the shooter like a glove. If $2,500 seems a lot to pay for an air rifle — just try winning the World’s with something less!
From the Czech Republic came the KalibrGun company with a range of precharged pneumatics. According to their spokeswoman, the specs are fluid, but they did show a bullpup called the Colibri, assumedly after the world’s smallest (2.7mm) firearm. It’s a tiny thing they’ll offer in .177, .22 and .25…but they were somewhat vague on the velocities as apparently some things are still in flux. Besides being a bullpup, it’s also semiautomatic! Unfortunately, it takes a 300 bar (4,350 psi) fill according to their literature (the sales rep told us that 250 bar is recommended), so I don’t know what the U.S. reception will be.
The KalibrGun Colibri is a semiautomatic bullpup.
BSA & Gamo
BSA is located in the Gamo booth, and they keep secrets about their products better than the National Security Agency! I did photograph the BSA Buccaneer SE for you. It appears to be a precharged carbine and I’m sure that someone in the world knows something about it, but they weren’t in the booth at this show either time I visited. Perhaps the intelligence community will discover something about this airgun at some time this year. If they do and I learn of it, I’ll be happy to share it with you.
Years ago, when BSA was a UK company, the airguns they made were well-designed and had remarkably accurate barrels. Let’s hope some of that tradition has carried over to the newest crop of guns!
The BSA Buccaneer SE is a pretty little PCP carbine. It looks like it can shoot!
As far as the Gamo guns go, I couldn’t make out what was new and what wasn’t. A lot of them were on display, but the confusing plethora of names lead me to abandon the quest. When Pyramyd Air gets some in this year, I’ll test some of them for you.
Crosman got a healthy exposure in the first report due to the Nitro Piston 2. But I didn’t get the full tour until the third day of the show. Let’s start with the AK BB gun that everybody was talking about before the show. It’s called the Comrade AK and is a semiautomatic BB gun that gets 150 shots per 12-gram CO2 cartridge. Yes, that was the number I was given for a 400+ f.p.s. BB gun!
The Comrade AK BB gun is semiautomatic and gets 150 shots per CO2 cartridge, according to Crosman.
I was also shown the new 760 that has been redesigned for greater velocity and easier pumping effort. They lengthened the pump handle to lighten the load and strengthened the pump rod and pump cup to make the mechanism more efficient.
There are also a couple airsoft guns I’m really excited about. One is an automatic electric pistol that fires both semi- and full-auto. There aren’t many full-auto handguns in the world, so I’ll let you decide which one this looks like. I hope to test one for you soon.
The GFAP13 BB gun is semiautomatic and gets 140 shots per CO2 cartridge, according to Crosman.
There’s also a Chicago Typewriter (Tommy Gun) that’s a fun AEG. It has an 800-round BB drum that winds on the outside — just like the real thing! I want to test one of these as well.
Finally, I saw a very neat looking CenterPoint dot sight that has a laser built in. So, it’s both a dot sight and a laser sight! I don’t think I’ve tested one of those before! This one is a high-quality holographic unit.
CenterPoint dot sight features both red and green dots, as well as a red laser!
Well, this is the last day of the 2014 SHOT Show. If I see anything new today, I’ll stick in one of the reports next week.

Today, we’ll begin testing the accuracy of the Crosman MK-177 multi-pump pneumatic. Because this rifle shoots both pellets and BBs, I’ll test both, but not at the same time and not in the same way. Today’s test of lead pellets was done at 10 meters, using the iron sights provided with the rifle.
I decided to use 5 pumps per shot for the entire test. That was both easy to do and was also pretty quick. According to the velocity test we did last time, Crosman Premier lites were averaging just over 500 f.p.s. on 5 pumps.
It took five shots to sight in the rifle. The first shot was 3 inches high and 2-1/2 inches to the right. Crosman supplies a sight adjustment tool with the MK-177, and I had to use both ends of it. One end is a flat-bladed screw driver that moved the rear sight to the left. The directions are printed on the sight, so there’s no confusion.
The front sight had to be raised because the rifle was shooting too high, so I unscrewed the front sight post several turns. Shot 2 was about three-eighths of an inch too high and three-eighths of an inch too far to the right. The hole was in the black bull, but it wasn’t centered. So, I made small adjustments to both the front and rear sights and fired again. This shot cut the 9-ring, which was close enough for me. I fired the other 2 shots, and they landed near the third shot. Sight-in was finished.
Crosman Premier lites
This is a Crosman rifle, so the first pellet I chose to test was the Crosman Premier lite. The first pellet hit the 10-ring of the bull, so I stopped looking through the spotting scope and just shot the gun. After the 10th shot, I looked at the target and saw a disappointing horizontal group that measured 1.173 inches between centers. None of the shots had been called as pulls (meaning the sights were off target when the gun fired), so this group surprised me.
Air Arms Falcons
Next to be tried were the Falcons from Air Arms. They’re domed pellets made by JSB and weigh 7.33 grains. Once, again, the first shot cut the 10-ring, and I never looked after that. This time, the group was much better, measuring 0.839 inches between centers. It’s also much rounder than the Premier lite group, leading me to think the rifle likes this pellet better.
The rifle’s behavior
At this point, I’ll comment on how the rifle performs. Shooting for accuracy I found the left-mounted cocking handle to be less of a problem than it had been when I tested the velocity. My procedure was to cock the bolt, advance the magazine, close the bolt, then pump the gun. This became a routine after a few shots, and it went surprisingly fast.
I rested the rifle on a sandbag for the shooting. Though it’s very light, the rifle was dead calm on the bag. The sights did not move one bit. And the MK-177′s trigger is so light and smooth that I found it very easy to shoot this way.
Pump effort identical to the 760
A reader asked me last time how this rifle compares to the 760 Pumpmaster in pumping effort. Silly me! I should have realized that the MK-177 is a 760 in another skin, but I tested my 40th Anniversary 760 just to make sure. The pumping effort is identical; or if there’s a small difference, the 760 is slightly harder because the MK-177 pump arm is a little longer.
The next pellet I tried was the RWS Hobby. These fit the clip a little tighter, and I could feel some resistance when the bolt pushed them into the breech. Again, I checked the target after the first shot then never again until I was through. I noted that this pellet moved over to the left side of the bull with no change to the sights. There’s a lesson to remember!
Hobbys grouped very close to Falcons, with the difference being due to measuring error more than any real practical difference. Ten Hobbys went into 0.858 inche…again, the group is fairly round.
Ten RWS Hobbys made this 0.858-inch group at 10 meters. This is so close to the Falcon group that it’s too close to call. Hobbys are wadcutters which cut cleaner holes, and may have lead to their group measuring slightly larger.
H&N Match Pistol
At this point, I was ready to declare the MK-177 to be an accurate multi-pump, but I had one more pellet on the table to test. And that one was the H&N Match Pistol pellet — another wadcutter. I’ve had remarkable results with H&N Finale Match Pistol pellets in some target rifles, but the straight Match Pistol pellet has never done better than average. Until this test!
Ten pellets went into a group that measures 1.239 inches between centers. No record there! But look at the tiny group that 9 of those 10 pellets made! It measures just 0.399 inches and is very round! Ladies and gentlemen, I think we have a winner!
From the results seen here, I think the MK-177 is a very accurate air rifle. It’s worthy of a 25-yard test with an optical sight. I’m thinking the red dot sight I’m using on the TX200 Mark III would be good for that. Before I do that, though, I’ll test the rifle with BBs at 25 feet.
So far, the MK-177 is a real winner! I enjoy the ease of use and the accuracy. If I didn’t already own a 760 and an M4-177, I would, perhaps, buy this one.

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!

Blog reader J was alert and noticed that I had not yet done the accuracy test of the Crosman 2100B multi-pump. I was astonished to find that he was right, so today we’re going to look at it. But before we do, I want to show you something I did at the range last week. Some of you who have been reading for a long time will remember that over a year ago I was suffering from eye problems. It turns out that my diabetes had dehydrated me so much that my eyesight was affected. And it took a long time for the situation to correct itself. I wondered if I would ever be able to shoot with open sights again.
This past Thursday, I was out at the range testing several firearms and airguns and a friend of mine happened to bring his Remington RangeMaster model 37 .22 rimfire target rifle for me to try. The model 37 was Remington’s equivalent to Winchester’s model 52 target rifle until the model 40X was created, and it (the model 37) has the reputation of being incredibly accurate. My friend can no longer use open sights and is scoping all the rifles he intends to keep. But this one is a rifle he has owned for decades but never shot. It still has the factory non-optical target sights.
The Lyman 17A front globe has a post-and-bead like target shooters used back in the 1930s and earlier. You put the post at the 6 o’clock spot on the bull. With good eyes, this kind of sight is considered second only to a properly sized aperture front sight out to 200 yards, and world records have been set with it. But notice I said, “With good eyes.”
I shot it at 50 yards with Winchester Super-X high-speed ammo, which is hardly target ammo! When I saw the group made with five shots I was ecstatic, because it proves that I can still see good enough to use open sights. I stopped at only five shots because who wants to ruin a group like that? However, after an involved trade with my friend, I ensured many more years of shooting this 37, and eventually I will shoot 10-shot groups. That’s important for today’s report, because the Crosman 2100B has a square post-and-notch sight, and the front has a bright green fiberoptic bead.
Next, I tried my custom .17 HM2 that this same friend made for me on a Mossberg 44 US action. This rifle has a Leapers scope, so there’s an even better chance of hitting the target. This time, five shots went into 0.266 inches at the same 50 yards. I was on fire! Unfortunately, I haven’t yet mounted the scope on the FWB 300S, so I didn’t have that to test, but everything I shot that day went where I wanted. Since I couldn’t see the group through my scope, I knew it was a small one. And, once again, I chickened out after 5 shots. If I were reporting on the guns and shooting for the record, I would have shot 10 shots with each gun.
Five shots in 0.266 inches at 50 yards with a scope. Not that much better than open sights. It looks better because the .17-caliber bullet is smaller, but the actual size of the group isn’t that much less than the first group.
On to today’s test
I decided to begin shooting pellets with the 2100 at 10 meters. That way, if the rifle proved somewhat inaccurate, I could still keep them inside the trap. The 2100 has a .177 rifled barrel, so pellets should be more accurate than the steel BBs it also shoots. Since this is a Crosman rifle, what better to begin than with 7.9-grain Crosman Premier 7.9-grain domes?
The first thing I did was oil the pump head with several drops of Crosman Pellgunoil. I did that for the velocity test, as well; but since it’s impossible to overdo this step and it does ensure the best compression, I did it again.
I decided on 5 pumps for this test because the velocity test showed that was enough to get all pellets into the 500 f.p.s. range. At 10 meters, that’s all you need for good results. So, this test was very easy on me.
A new way of loading
Many owners may already have discovered what I am about to share; but while I was shooting the Premiers, I discovered a foolproof way of loading them. The loading port on the side of the rifle is too small for most adult fingers, and until now I’ve found it difficult to load the pellet so the head points forward. But during this test, I accidentally discovered that I could drop in a pellet in any attitude and simply elevate the muzzle of the rifle with the receiver rotated to the left so the loading port is angled up. The pellet would then try to right itself at the bottom of the loading channel; and, if it wasn’t aligned, all I had to do was push it forward slightly with the cocking handle and then pull the handle back and the pellet would align itself every time. I tried this with the JSB Exact RS pellets, as well, but they got stuck and didn’t align as easily as the Premier lites. I can’t wait to try this method on my old Crosman 2200.
Sights are okay, but not great
I found the sights easy to acquire and very sharp and crisp, but the method of adjustment leaves a lot to chance. I never did get the group shooting where I wanted it. Also, though I elevated the rear sight nearly all the way, it was still just hitting at the point of aim at 10 meters. Forget about shooting longer distances unless you learn how to hold the front post above the top of the rear notch. But the sights are not important, because this will not be the last test of this rifle. Just like the M4-177 rifle I tested last year, I found the 2100B was far more accurate than the price indicated! In a word, it was phenomenal — which is why I told you about the state of my eyes in the beginning of the report.
Next, I tried the JSB Exact RS pellet. I was expecting to see a similar group, which is why what I got surprised me so much.
What a difference! Crosman could use this as an ad testimonial for Premiers, if they wanted. We all know that the JSB Exact RS is a premium pellet; but in this rifle, the Premier lite is the clear and obvious choice. I already demonstrated that my eyes are up to the task, so there’s nothing to blame in this case but the pellet.
After testing two pellet brands, I switched to Crosman Copperhead BBs and fired 10 from a standing supported position at 22 feet. If the group was small, I would then try other brands of BBs, but as you will see that wasn’t necessary.
Ten Crosman Copperhead BBs went into this 2.219-inch group at 22 feet. This demonstrated that it wasn’t worth pursuing BBs any further. My photo inadvertently cropped off a BB hole on the right of the group. It’s on the 5-ring, as it ends on the right margin.
This rifle is deadly accurate with Crosman Premiers and not very good with BBs. I wouldn’t even bother with BBs in the 2100 anymore because I have a host of BB pistols that will out-shoot it. But with Premier lives, it’s a different story.
The 2100B has earned the right to a special 25-yard test with a scope sight. That will come in Part 4, and I charge blog reader J with making sure I don’t forget to do it!
by B.B. Pelletier
Today, we’ll look at the velocity of the Crosman 2100B multi-pump, and a strange thing occurred during the test. Actually it was two strange things — one an amazing coincidence and the other just weird. Both relate to oiling the gun, and both will be informative.
First, the coincidence. As I was writing this blog (last week, because I’m in Las Vegas at the SHOT Show this week), I got a question from a reader whose 2100 wasn’t pumping air. I asked him if he had oiled the pump piston head like he was supposed to, and I directed him to the online owner’s manual that tells how to do it and to a blog I wrote years ago that tells the same thing. A couple hours later, I get a thank you message that he’s oiled the gun and it seems to be holding air.
So, there I am in my office pumping the gun and shooting it for velocity and I ask myself about the state of the pump piston head of the particular gun I’m testing. Sure, it’s brand-new, but that doesn’t mean that it has enough oil. I look, and the pump head appears to be dry. For those who wonder what I’m talking about, please read the manual.
Then, I recalled that someone had guessed that this rifle would shoot in the low 600s with lead pellets, because someone he knew had tested it. Lo and behold, it was shooting only about 622 f.p.s. on 10 pumps (which is the maximum) with Crosman Premier 7.9-grain pellets. Wow! He was right!
But, wait! The pump head was dry, so I oiled it with some Gamo oil for CO2 guns. The velocity jumped to 658 f.p.s. with the same pellets and 10 pumps. But after about 10 shots the velocity started declining again.
So, I oiled the pump head again — this time with Crosman Pellgunoil. The velocity jumped to 690 f.p.s. before sliding backward to the 620s.
What did I learn?
First, I re-learned for the umpteenth time how important it is to oil a multi-pump gun. That was all it took to fix the reader’s rifle! Second, I saw that the test 2100 rifle responds to oiling immediately, but falls off again almost as fast.
So, the published velocity of 725 f.p.s. can probably be achieved with real-world lead pellets for a brief time, but this test gun won’t hold that velocity very long. Maybe the material the pump head is made of needs a break-in period? I don’t know. What I do know is that I can change the velocity of this gun by 70 f.p.s. simply by oiling it.
It doesn’t end there, however. While that story was unfolding I was also experimenting with the speed of my pump strokes. Since the pump head seemed somewhat hard, I figured that faster pump strokes would build more pressure. And they did! I could increase the velocity by 10 f.p.s. at least, just by changing the speed at which I pumped. I’ve tried the same thing in the past with other multi-pumps, but this one is particularly sensitive.
I think the most representative method of testing this rifle for velocity is to let it sink back to its lowest velocity and stabilize there. That way, the velocity test will also represent the velocity at which the accuracy test is conducted, because I’m certainly not going to oil the pump head after each and every group! Undoubtedly, there’s sufficient oil in the gun right now because of the two oilings I mentioned.
The first pellet tested was the 7.9-grain Crosman Premier. Since the 2100 is a multi-pump, I decided to test each pellet and BB at 5 pumps and 10. That gives us a good picture of what the gun can do across the entire range.
On 5 pumps, Premier lites averaged 540 f.p.s. when the gun was pumped fast. They ranged from 537 to 543; and at that velocity, they produced 5.12 foot-pounds On 10 pumps, again with rapid pump strokes, this pellet averaged 630 f.p.s. The range went from 628 to 635 f.p.s., and the average muzzle velocity was 6.96 foot-pounds.
JSB Exact 8.4-grain dome
Next I tried the 8.4-grain JSB Exact dome. On 5 fast pumps they averaged 526 f.p.s., with a spread from 517 to 531 f.p.s. The muzzle energy averaged 5.16 foot-pounds. On 10 pumps, they averaged 608 f.p.s. with a spread from 595 to 611 f.p.s. The average muzzle energy was 6.9 foot-pounds.
JSB Exact RS
For a light pellet, I tested the JSB Exact RS. The name of this pellet includes the word Match, but they’re domes, not wadcutters, and cannot be used in formal match shooting. At 7.33 grains, they’re very light, yet I’ve had some good luck with them in other pellet rifles.
In the 2100, 5 pumps gave an average 559 f.p.s. The spread went from 555 to 563 f.p.s. The average energy was 5.09 foot-pounds. On 10 pumps, the average velocity was 646 f.p.s., and the range went from 635 to 654 f.p.s. At the average velocity, the muzzle energy was 6.79 foot-pounds.
So, the reader who said the 2100 wouldn’t get to 700 f.p.s. was right. As long as you don’t shoot it immediately after oiling with Pellgnoil, it won’t shoot that fast. But oil it, and it’ll probably top 700 f.p.s. with lighter pellets.
On to BBs
BBs were next, and with them things are much more standard. Though there are subtle differences in BB brands, they don’t vary as much as pellets. We’ll now see if the advertised velocity of 755 f.p.s is reasonable. Since this is a Crosman gun, I tested it with Crosman Copperhead BBs.
BBs are loaded into the large reservoir, then the gun is shaken and they fall into the smaller spring-loaded magazine. Once the magazine is empty, you can shoot pellets again, even though there BBs are still in the big reservoir; if they aren’t in the magazine, they won’t load automatically.
On 5 pumps, Copperheads averaged 570 f.p.s. They ranged from 564 to 578 f.p.s. At the average velocity, they generated 3.68 foot-pounds of energy at the muzzle. On 10 pumps, they averaged 678 f.p.s. and ranged from 672 to 682 f.p.s. That’s an average muzzle energy of 5.21 foot-pounds.
So the bottom line is that the test gun doesn’t meet its advertised spec for velocity. It falls at least 73 f.p.s. short. It does the same with lead pellets, so I’m withdrawing my remark that the gun is suitable for light hunting. Clearly, it’s below the safe margin. Yes, it will kill small animals, but I could not recommend it for that task based on these results.
I also note that the barrel is starting to loosen at the breech. It rotates slightly at this point, and I’ll keep an eye on it. And the pump lever hits the gun with a loud slap on every pump stroke — there’s no cushioning material to deaden the sound.
I hope these results don’t disturb owners of this gun, because they in no way condemn it. The accuracy test is still to come, and we might get a big surprise there.

I’ve been reviewing some basic and even classic airguns and air rifles for the past month, and today’s Crosman 2100B multi-pump is one of them. It was initially my plan to get all these at least started by Christmas 2011, but I didn’t even make that date. Next year, I need to start in early October, because other things do get in the way.
I know many of you are 2100 fans because you’ve said as much in the comments.
I may be the last guest to come to the party where the 2100 is concerned. Only Crosman’s smoothbore 760 Pumpmaster is more popular; and, of course, with the release of the rifled M4-177 late last year, that will be a tough act for any airgun to follow.
Think of the 2100 as the 760′s older brother, though there are a couple very important differences. For starters, this powerplant is completely conventional. You can pump the gun and leave air in the reservoir without cocking it first. That’s a big plus in my book. And the piston stroke in the 2100 is longer than that of the 760, so the power is greater, as well. Best of all, the 2100 has a rifled barrel!
The power level is elevated over that of the smaller multi-pumps. Crosman rates the rifle at 755 f.p.s. with steel BBs and 725 f.p.s. with lead pellets. Naturally, I’ll test both numbers for you, and Crosman Copperhead BBs will be involved. So, this is a more powerful airgun than most of the others in its class.
The sights are a fiberoptic bead in front and a plain notch in the rear. The rear sight is adjustable in both directions, though the adjustments are crude. There’s an elevator wedge for elevation, and the entire sight can swing in either direction for windage. A screw then locks it in place.
The stock and forearm/pump handle are plastic, but the rest of the exterior of the gun seems to be metal. Only the bolt handle and barrel band are plastic, while the exterior of the barrel is jacketed in some metal around a soda-straw steel barrel. This barrel is rifled, as mentioned, yet the rifle can handle steel BBs if you’re so inclined.
The bolt retracts to open a funnel-shaped loading port, similar to what we saw in the review of my vintage Crosman 2200 multi-pump rifle back in 2009. I’ll wait until I’ve loaded the gun several times before reporting on how easy it is to load. Naturally, this time, there are also steel BBs to be loaded from an internal reservoir, so I’ll cover that later as well.
The effort needed to cock this gun is considerable, and buyers should know that before they buy. This isn’t the gun to pick to train your 10-year-old. Think of it as more of an adult pneumatic. I compared it to my vintage 2200, which is much easier to cock, so there’s a possibility that this will wear in with time and use.
Most people love the 2100!
I looked at the owner reviews of the gun, and only one of them was really negative. Apparently, the buyer expected a $125 rifle for $60. He said the barrel is plastic, but it isn’t. It’s metal, but as noted, it’s just a jacket around a soda-straw steel barrel. He was terribly upset about the construction of his gun. So much so that he forgot to report how it shot.
There were 32 others, however, who gave the gun five stars, and I think what they say is a lot closer to the truth. I’ve tested Cannon multi-pump air rifles from Indonesia that are all metal and wood, but don’t shoot worth a darn until their valves are rebuilt by their owners. Even then most of them don’t even perform to spec, and only after they’re made to work at all do the owners discover that the barrels are often less than accurate. I expect more from this Crosman rifle and will be shocked if I don’t get it. A little plastic where it doesn’t matter (and, no, Michael…the one person who gave this a negative review, the bolt handle will not break when you cock the gun — even 10,000 times!) is not a detractor if the performance is there. That’s what this report will determine.
Weight-wise, the 2100 is light, but not overly so. At just 4.8 lbs., it lays light in your arms but it doesn’t float the way many similar smaller multi-pumps do. For many people, that’s a good thing. The length of pull is an adult 13-3/4 inches that will work for older kids, as well. The molded plastic stock and forearm are both checkered with large, sharp diamonds that really do grip your hands. Overall, the rifle feels pretty good in the offhand position.
Pellets are loaded singly, but the BBs are poured into a 200-shot reservoir that’s accessed through a discreet hole in the bottom of the pistol grip. Just slide the grip cap to the rear and pour in up to 200 BBs. Pull the BB magazine follower to the rear and lock it in place, then, while holding the muzzle down, shake the rifle from side to move BBs into the 17-shot visible magazine on the left side of the receiver. Finally, release the BB follower. Every time you cock the gun, a magnet on the bolt tip will grab a BB until the BB magazine is empty. It’s possible to have BBs in the larger reservoir and not in the magazine and to shoot pellets single-shot without BBs getting in the way.
I measured the trigger-pull with my Lyman electronic scale. The trigger is two-stage with a very short first stage. It’s not adjustable. Stage two breaks very consistently at between 4 lbs., 10 ozs. and 4 lbs., 12 ozs. — as long as the squeeze is slow and consistent. Yank the trigger, and the pull goes over 5 lbs. on the test gun.
I have to comment on the effort it takes to pump this gun, because it could surprise some buyers. Where the 760 Pumpmaster and its derivatives all pump easily, the 2100 does not. It pumps as hard or even harder than a Benjamin 397 multi-pump. I may need to measure this for you. I checked it against my 2200, and it’s close to the same effort for both, so this is probably not going to change.
Yes, and no. Yes to the five percent who can reliably hit a quarter at 30 yards offhand five times out of five. And no to the rest who can’t, but just want an extra-cheap airgun to do what it isn’t made for. And the five percent are also the ones who know better than to try to hunt with such a light air rifle.
Yes, this airgun probably has enough power to take very small game humanely at close range. Unfortunately, too many shooters will try to stretch the distance well beyond what the gun can reliably do. So, please, think of the 2100 as a plinker and not as a hunter.
This will be another enjoyable rifle to test, because it has so much going for it. No wonder it’s a classic — it feels and handles right!
