The Advanced Armament Corp Ti-Rant 9/EVO-9 Suppressor Piston with an M13.5×1 left-hand thread (brand part no. 64191) lets a Ti-Rant 9 or EVO-9 suppressor swap between 9mm host pistols with different barrel threads simply by changing the piston rather than the whole suppressor. Constructed from heat-treated stainless steel with a bead-blasted matte finish, each piston is engraved to show its thread diameter, pitch, and rotation direction for correct installation. This M13.5x1LH version will not work with Ti-Rant 9M-HD suppressors, so confirming your specific model before ordering matters. It ships as a standalone service part, separate from the suppressor.
