B&T Quick Detach
Allows the operator to enhance the weapon system with B&T QD suppressors.
Breacher Spikes
These sharp and hardened steel spikes allow the user to destroy barriers in CQB situations.
Expansion Chamber
The construction guides the exhaust gases in optimal direction to reduce recoil and muzzle flip.
Crush Washer
Mount the AR-15 SOF Compensator with the crush washer to ensure the correct alignment on the barrel.
Closed Bottom
Prevents blown up dust and debris.
Compatibility: All AR-15 and M16 variants in .223 or 5.56 mm caliber with a barrel thread of 1/2 x 28 TPI UNEF, for example: Hera Arms The 15th, Schmeisser AR15, DPMS AR-15, etc. Does not fit Oberland Arms OA-15
Installation: Dismount existing muzzle devices and clean the thread surface. After applying a drop of oil on the thread, put the crush washer over the thread (the conical end facing towards muzzle). Screw the compensator clockwise on the barrel by hand until it fits snugly. Then use a 19 mm wrench to tighten the compensator until the Claw Gear logo faces upwards.
