2100B Air Rifle

Crosman 2100B Air Rifle

Crosman 2100B Air Rifle is an impressive product for anyone who shoots. It’s light, compact, accurate, and easy to use. Plus, it looks awesome. This gun fired ten Crosman Premier pellets (sold in the cardboard box, not the metal tin) into a group of 0.539″ at 10 meters.

I’ve owned this gun for many years now. It’s a really nice gun and still works as well as it did the day I bought it. 

If you want a gun that puts rounds where they are supposed to be in relation to where you are aiming, get this gun. Pump the 2100B from 3 to 12 times, depending on how far you’re shooting.

This full size powerhouse lets you fire pellet and BBs at speeds of up to 725 fps and 755 fps respectively.

10-meter test

For the ten-meter test, after shot 5 times for every pump.

This rifle has a scope mounted. So now it’s easier to pump, because I don’t have to hold the rifle at the optimum place and can hold it farther away, which gives me more leverage.

It’s heavy, rugged, and will work well for years.

To hold the gun farther back, your hand has to move around farther to the back. This winds up being the pistol grip of the stock.

This is not the best leverage for pumping the rifle, but the 2100B is equipped with a short, easy stroke.

25-yard test

For this 25-yard test, after fired the rifle six times for every shot.

I wanted to get a feel for how fast the pellets fired and how accurately each pellet hit the target.

If you want to make sure that your bore is ready to go before you use it, this would tell you whether the shots were walking or if the bore needed to be seasoned with each new pellet.

So, after shooting each pellet, you should see which one is worth the effort to shoot a full 10-shot group.

The first pellet tried was the 7.9-grain Crosman Premier dome. The first five shots looked fine, but it was better to just keep shooting. After 10 shots the grouped pretty well, so I just kept going.

Ten shots landed in a group measuring 0.809 inches between centers. The shot is a little wider than it is tall, but you can see that 9 of the 10 shots are grouped around a round shape.

10 Crosman Premier lites didn’t do bad at 25 yards. Nine of them made a nice round group. In total group the center of the lens is 0.809 inches between the centers.

The results of the 10-meter test were much higher than expected. The best group size for a product in a size test is 10 (about half a point), because you’re going to see less movement in that

I think that shows how much better an optical sight is than an optical rangefinder. Shooting a multi-pump rifle can make you feel like it takes a lot longer, but it isn’t. To shoot a gun accurately it takes practice to become good at it.

The slower pace forces the shooter to concentrate more on what he’s doing. Single-shot guns are really fun. You can fire them at targets, and your skills come alive.

Wanted to try the new Superdome pellets from Redwood Shooting Supplies. They had a really good demo set up and I was able to get my hands on them. It’s a good round that I rarely shoot.

The bullets are made from pure lead, so they have a fairly thin skirt that takes well to the rifling. I was pleasantly surprised by the fact that it performed very well in comparison to a Premier lite. I wanted to see how it would perform against some of the more expensive blends.

This group consists of 10 Superdomes that measure the same as the group of Premiers, which is 0.809 inches between centers. While the group may appear larger, there is no measurable difference between the measurements of the groups.

Pros – Nice Price

This is a great rifle to start with for young shooters. If you get this rifle at an early age, it will teach you valuable lessons about proper technique, trigger control, and gun safety. It also comes in a package that is easy to carry, store and transport. The best part is it is a good value for the price.

For the accurate, it is windage and elevation adjustments on the barrel the same as Legacy 1000 (awful). There is a nice weight. Nice way of handling it. This is comparable to other variable air pumps in the same price range.

Pro – Accurate

We would shoot squirrels in the head at 50+ yards, and let me tell you, it was an accurate air rifle. I recently purchased another one at an auction, and I was shocked to learn it had a leak.

Replaced the valve assembly, pump, and a couple of o-rings.It is now a shotgun with a RWS super dome. 5 shot groups in one hole at 25 yards. 50 yards and the holes are touching.

I put a new scope on my shotgun and this thing blew me away at 100 yards, even though it’s a pump action. I was shocked that a gun can hit so accurately at such a great distance. Even if you can’t put holes through holes at 10 feet, you still need to hit the ball more solidly.

Pro – Powerful

Unlike some other pumps this one comes with a metal receiver and that’s an amazing feature for children. It’s no longer a problem to get a hold of these guns.

I shot this particular example on a Crosman Competition Wadcutter, which has traditionally performed quite well for me. These guns use variable amounts of pressure to power them, which is a nice feature. This will allow my kids to pump them up for higher power when hunting and lower power when plinking cans or targets.


This rifle is built like a tank. It doesn’t matter if you have to break it down for transport. It’ll last. The Legacy 1000’s all-black color scheme is definitely nicer, but I’d love to have it on this rifle, too. 

The receiver, trigger guard and trigger on the 2100 are made of metal (unlike the Legacy), giving me a much stronger impression of overall quality.

This rifle to replace Legacy 1000, but the Marauder maybe even better. It’s faster and more accurate.
