An AAC piston 1/2×28’s a suppressor accessory designed by Advanced Armament Corp (AAC) for use with their pistol suppressors, such as the Ti-RANT series. The 1/2×28 thread pitch fits most 9mm and .22 LR threaded pistol barrels. This piston allows the suppressor to function properly with the recoil operated action of semi automatic pistols. It works with AAC suppressors, compatible threaded barrels, and various handguns, enabling reliable and quiet operation across multiple pistol platforms.
