The B&T APC9/SPC9/GHM9 RBS silencer will quickly attach to any standard 9mm 3-lug muzzle device as it utilizes a modified gate-lock style 3-lug mount. This allows for extra security and prevents wobble when compared to traditional 3-lug systems. This suppressor is designed for subgun and PCC use yet comes in weighing only 14.4 ounces.
