AAC Ti-RANT 45 Piston to .578×28 | Advanced Armament Corp

This AAC piston enhances the versatility of an AAC silencer by allowing the suppressor to be swapped between host firearms with different barrel threads. Converting the suppressor to a different barrel thread pitch requires selecting the proper piston and replacing the existing piston in the rear of the sound suppressor. AAC pistons are constructed of heat-treated stainless steel with a bead-blasted matte finish and are engraved to indicate thread diameter, thread pitch, and direction of rotation for installation.
