The IWI Left-Hand Quick-Detach Muzzle Brake (brand part no. IWSQDMB24) threads onto a 5/8×24 muzzle to reduce felt recoil and muzzle rise, while also serving as the mounting interface for a compatible larger-caliber IWI quick-detach suppressor. The left-hand threading keeps the brake from backing off under recoil during normal firing. Run bare, it functions as a standard muzzle brake; with a compatible IWI suppressor attached, it becomes the fast, tool-free mounting point.
