Crosman 2240 Air Pistol Teardown Review

The Crosman 2240 is a very popular bolt action, single shot CO2 air pistol. In production since 1999, this air pistol has a huge, devoted following of enthusiasts, who love its simplicity and ability to be customized. It’s powered by one 12 Gram CO2 Powerlet and is available in .22 caliber.

So many aftermarket parts have been made available for the Crosman 2240 air pistol that it’s almost possible to create an entire custom 2240 that retains only very few original Crosman parts – usually the gas tube and pistol grip frame. In fact, the 2240 is ideally suited as a first airgun customization project.

Here’s the 2240 with the CO2 Powerlet, piercing cap, side plate and grips removed. Only one grip is shown for simplicity.


The 2240 has a plastic breech with no provision for attaching a scope or red dot sight. This plastic breech is normally replaced by a steel breech – available from Crosman and third party suppliers. Steel breeches allow scopes or sights to be mounted and give the pistol a more solid feeling.


Barrels with different lengths are available from Crosman and are easily interchanged for the standard 7-inch barrel supplied with the 2240. Longer barrels can give higher muzzle velocity with CO2 airguns and also increased accuracy.


2240 trigger and hammer assemblies are simple. The trigger pull weight of the standard 2240 is quite heavy and many solutions for achieving a lighter trigger with more feel are available from aftermarket suppliers. Note the tiny steel ball and spring – these are parts of the safety mechanism and are often lost when disassembling this air pistol.

The 2240 valve is also a simple design. The sharp pin pierces the Powerlet when the 2240 is first fired, thus charging the air pistol with gas. In use the Powerlet presses against the orange-colored disk and the system is sealed. If your 2240 develops a leak, it’s most likely to be from this seal.
