This AAC Piston significantly enhances the versatility of your AAC Silencer, enabling seamless swapping between various host firearms with different barrel threads. To convert the silencer for compatibility with a different thread pitch, simply select the appropriate piston and replace the existing one located at the rear of the suppressor. Crafted from heat-treated stainless steel and finished with a bead-blasted matte texture, all AAC pistons are designed for durability and reliability. Each piston is engraved to clearly indicate the thread diameter, thread pitch and direction of rotation for easy installation. Please note that this piston is not compatible with Ti-RANT 9M-HD silencers.
