The BOSS 6.5mm Brake End Cap for 1.5-Inch Housing in black (brand part no. EC-150-65-SS-BR-BLK) is the self-timing brake end cap for B.O.S.S. silencers, sized for .264 caliber (6.5mm) bores. B.O.S.S. built it for shooters who want more muzzle control without going back to a separate muzzle brake, while still letting them dial in the sound performance of a B.O.S.S. silencer. It is machined from 17-4 stainless steel and weighs 3.4 ounces. It fits only B.O.S.S. 1.5-inch tubes, and the suppressor is sold separately. It suits a 6.5mm rifle owner who wants a flatter shot-to-shot recovery.
