Pistons for our booster, available in a variety of thread sizes, including all industry standard options.

(For the 16×1 pistons, these are threaded to fit barrels with the non-threaded extension, such as factory threaded HK45’s and similar. If yours is threaded all the way to the muzzle or if you’re unsure, send us an email at support@libertycans.net and we’ll be able to help you out.)
