The AAC Ti-RANT 45 Piston (brand part number 64198) swaps onto the rear of an AAC Ti-RANT 45 suppressor to change its host-barrel thread pitch to .578×28. AAC builds each piston from heat-treated stainless steel with a bead-blasted matte finish, and engraves it with the thread diameter, thread pitch, and direction of rotation to make installation foolproof. Swapping pistons is the only step needed to move a Ti-RANT 45 between host firearms with different barrel threads, without needing a separate mount or adapter. It’s chambered for .45 ACP hosts.
