*B.B. Pelletier tested the Crosman 2100B air rifle for our airgun blog (click link elsewhere on this page). Using open sights, this gun delivered 10 Crosman Premier pellets (Premiers sold in the cardboard box, not the metal tin) into a 0.539" group at 10 meters. If this gun retailed for $300, that wouldn't surprise anyone...but it's a fraction of that. If you enjoy accuracy combined with variable power, get this gun!

Pump the 2100B from 3 to 10 times, depending on the distance you're shooting. Light in weight, this full-size powerhouse launches pellets up to 725 fps and BBs up to 755 fps.

Never pump your 2100B more than 10 times!

Things I liked: Was fun to use while it worked

Things I would have changed: On the fifth time brining the gun out of its box, the rivet that held the pump handle to the pump lever started to come out.I had to keep pushing it back into the hole to keep using the gun. However, one time it came out too far and it was quite a pain to get it back in correctly. Would have been nice if the company used bolts instead of cheap rivets.At least a higher quality rivet would have been nice.

What others should know: Don't buy this if you're in a state where air guns must be shipped to a licensed gun dealer (like NJ) in order to receive it. If so, you'll find it really isn't worth sending it back to be fixed. Sights had to be realigned when we received the gun.

Things I liked: Very lightweight, Easy to operate pump pellet gun , very accurate when you find the correct pellet that the gun likes. This gun is a great deal for 69.95 , I like that the gun has a metal receiver instead of plastic. The Crosman 2100 has a great following, like it so much I bought two of them , one new and one refurbished.

Things I would have changed: Make a wood stock version and a .22 model

What others should know: Bolt operation is very stiff at first but will loosen up with time.

Things I liked: Great rifle and pretty much as I remember it back in the early 80s. I had an early production rifle in 82' or 83', and other than the newer stock texture (I remember it being checkered) it is exactly the same. Some reviews state that it used to have a wood stock, all metal, etc., yet since I had one of the first production ones, I don't ever remember such features. Supper accurate with or without a scope. I put an old blurry out of focus 4x15 on after sighting in iron sights and it hardly increased accuracy because it was already so accurate with iron sights to begin with. Pumping is pretty easy given that it is a pump action air gun. After 150 pellets or so it has still remained tight with the pump handle and all parts still aligned up, no twisted pump levers and such. I like it.

Things I would have changed: Trigger...Trigger...Trigger is horrendous. I assume it is a safety feature given the youngsters that use it the most. I did take mine apart and polish the sear and engagement faces up some, afterwards it was much smoother, yet still a beast. 1 Star on the trigger, and 4 stars overall because of it.

What others should know: As others have commented, drop the barrel downward and then drop the pellet in head first to get the best results out of loading pellets. Also, based on size of the rifle and range potential, I'd stick with a small 4 x 15 or no scope at all, over a larger 1in or 30mm scope. As expected, it shoots Crossman pellets the best, particularly the 7.9 grain hollow points. I tried the Crossman 7.3 pointed and heavier 11.3 grain pellets, yet the 7.9s proved the most accurate by a long shot. I tried about 4 other brands / types and once again came back to the Crossman pellets as the best.

  • Julian from USA asked:

    Is the receiver metal or plastic

    • Stanley from USA:


  • Jeff from USA asked:

    The bolt or slide you pull back to load and the cock the gun seems to be excessively stiff and takes all I've got to click it back to load. Is this typical? Is there a way to make it easier to cock?

    • Stanley from USA:

      It is typical most are stiff but the more rounds fired it might loosen up.

  • Keithleong from USA asked:

    can you use plastic bb bullets

    • Stanley from USA:

      No regular bbs only.
