    Airgun Modifications: The Crosman 2240 Suppressor Project

    One of my first air pistols as a kid was the pump action Crosman American. Simple, cheap to shoot, and accurate enough for 10 year old Pete, that gun provided me with endless hours of neighborhood fun (I’d like to take this opportunity to publicly apologize to Mrs. Yamamoto for plinking the buds off of her well-manicured hibiscus bushes). The C02 cartridge version of the American is the Crosman 2240 – a bolt action pistol that can be had for about $75. Thanks to Larry, one of our readers, we were alerted to a Crosman 2240 suppressor project at Airgun are a lot of fun. They’re even more fun suppressed.

    Crosman @ TFB:

    A word of caution for any of you planning on designing and building a silencer for an airgun. While they are completely legal in the U.S., airgun suppressors should be made in a way that prevents them from being used on firearm hosts. For example, don’t use a 1/2 x 28 thread pitch that is common to rimfire suppressors or hosts. The chances of ever being questioned about your pellet gun can are slim, but you never know. The alternative is to apply for and obtain a Form 1 tax stamp for a firearm suppressor.

    Just a quick update on my latest projects. I’ve wrapped up the Daisy Red Ryder scope mount design and have moved on to the Crosman 2240. I have received a few requests to make a Suppressor for the Crosman DPMS SBR Full-Auto. I finally got one and will be working on that soon. I’m also taking a look at the Crosman PFM16 and Umarex SA10.

    The 2240 Suppressor is very simple. It requires you to remove the stock front sight by just tapping it off with a hammer and piece of wood. Then you just press the suppressor on by hand with the front sight aligned. The only unique feature is the integrated front sight post. It is very similar to the 1322 Silencer on the inside in that it is round and has cone-shaped baffles.

    The 2240 barrel has a flat ground on it that I used as an alignment feature for the front sight. I’m currently testing the Suppressor with various front sight post heights. I’m thinking that I might make it a bit on the high side. That way, it’ll cover close range shooting(if that’s your thing), but it could also be sanded down for longer range shooting. A benefit of the common ABS plastic blend used in 3D printing is that it dissolves in acetone. You can sand down the front sight post and use a paintbrush to coat the abraded surface with acetone to give it a smooth finish.

    The Crosman Scope Mounts have really proven to be a hit. I didn’t imagine that they would be so popular. I’m grateful for all the feedback. The mounts are self-aligning on the 13XX and on the 2240. Check out the Crosman 2240 with the Suppressor, Scope Mounts, and Hawkeye Reflex Sight mounted below:

    It may not look like it, but the cap and CO2 cartridge can be removed without removing the suppressor. Once the weather clears up outside here in Houston, TX I’ll shoot a little test video.

    Thanks for readin’ ya’ll!
