Want to swap your 9mm AAC EVO or AAC Ti-RANT silencer from pistol to pistol? You need the corresponding pistons in the correct thread patterns for your guns.
A.S.A.P. pistons are made to match the barrel threads of all popular factory threaded pistol barrels and many aftermarket barrels. All Evolution/Ti-Rant Series Pistons feature heat treated stainless steel construction, a matte bead blasted finish, and engraving to identify the thread diameter, pitch, and direction of rotation for installation (Left Hand threads or Right Hand threads).
