APA Gen II Fat Bastard Muzzle Brake M18x1 30 Cal GenII-FAT-18x1-30

The APA Gen II Fat Bastard Muzzle Brake was designed for larger calibers. Pound for pound this muzzle brake will not be outperformed by anything remotely close to it's size. It's not the same as a conventional brake. Instead of allowing to the gas to go to the area of least resistance, it performs more like a silencer and forces the gas out.
