This Advanced Armament ASAP Piston enhances the versatility of an AAC Ti-RANT 45 Silencer by allowing the suppressor to be swapped between various different host firearms with different barrel threads. All that's necessary to convert the silencer to be compatible with a different barrel thread pitch is to select the proper ASAP piston and replace the existing one residing in the rear of the sound suppressor. All AAC ASAP pistons are constructed of heat treated stainless steel with a bead blasted matte finish, and each is engraved to indicate the thread diameter, thread pitch and direction of rotation for installation. Made in the USA.
This is the "Short" AAC Piston that shortens the overall length of the Ti-RANT suppressor package on the host firearm. It is designed for use ONLY with 1911-Style pistols WITHOUT a Full Length Guide Rod or FNP 45 Tactical Pistols with a .578"-28 threaded barrel. This piston may also be used on a pistol with an extra-long threaded barrel. Clearance issues with the recoil spring guide rod during cycling may occur with threaded barrels of conventional length. If in doubt, please contact AAC for additional information.
