Convert your pellet gun to discrete firing

The silencer adapter for Crosman 2240, 2300T and 2300S allows you to attenuate the sound of your pellet gun. Therefore you will enjoy more discreet sessions, to have fun in the backyard without disturbing your neighbors.

Crosman spreads his excellent pellet guns all over the world. Among the most popular, we find single-shot CO2 airguns using a bolt action mechanism. These are models Crosman 2240 in .22 caliber, and Crosman 2300t and 2300s in .177 caliber. All will be compatible with the silencer adapter offered on this page.

How to use this silencer adapter?

The Crosman 2240, 2300T and 2300S silencer adapter replaces the original front piece of the gun. It does not screw on, but simply slip on the end of the barrel. Once the adapter is in place, it is tightened with a transverse Allen screw provided. Because the pellet gun does not generate any recoil, this reversible mounting mode is perfect.

Once the adapter is mounted on the weapon, you will enjoy a neat thread to screw a silencer. When no suppressor is mounted, we recommend to cover the thread with a suitable barrel thread protector . Of course, this isn’t an obligation.

Since this accessory is completely cylindrical, open sights of the host pistol cannot be used anymore. It is therefore more readily addressed to weapons equipped with a scope or a red dot sight. For die-hard open sights shooters, we also offer a silencer adapter for Crosman 2240 with front sight.

Which suppressor can I mount on my silencer adapter for Crosman 2240 ?

We offer this silencer adapter in 2 threads to choose from. The 1/2 UNF, or the 1/2 UNEF.

For information, the 1/2 UNF (also known as 1/2×20 TPI) is the standard thread for 22 LR silencers in Europe. On the other hand, the UNEF 1/2 (also known as 1/2×28 TPI) is the standard thread for .22 caliber suppressors in the U.S.A. Please choose yours according to the most common standard in your own country.

Please note that using a .22 LR silencer on your pellet gun is not a problem. Including if the gun is in .177 caliber.

  2. Craig (verified owner)

    Very hard to put on barrel & there is no thread cover when not using silencer .

      Hello Craig,
      Indeed we do not manufacture adapters like the Chinese with questionable tolerances!
      Our adapters fit within a few hundredths on the barrels, you have to be well aligned. This guarantees a very good precision and avoids “baffle strike”.
      Indeed to offer the adapters at the best price we do not provide the thread protection ring as it is written in the description, there is no bad surprise.
      The team
