The BOSS Chairman 7.62 titanium suppressor with a brake end cap is the lightweight build of the maker’s .30 caliber flagship, set up for maximum muzzle control (brand part no. CH-15080-762-TI-58-BR-BLK). Grade 5 6Al4V titanium baffles, mount and cap sit in a Grade 9 titanium tube with a 17-4 H900 stainless blast baffle, which brings the weight to 11.5 ounces without the mount. BOSS says the titanium version is so light you will forget it is mounted. The brake end cap favors recoil control, at some cost in sound reduction. It is a strong match for a carry-all-day .308 hunting or precision rifle that still needs fast follow-up shots.
