The FB (Fat Bastard) muzzle brake was designed with larger calibers such as the 338 Lapua. Pound for pound this muzzle brake will not be out performed by anything even remotely close to it's size. Instead of performing like a conventional brake and allowing the gas to go to the area of least resistance this brake performs more like a silencer and forces the gas out. The FB is machined from 416 stainless and is 1.125 in diameter.
