The Badger Ordnance FTE Muzzle Brake is a clamp on style brake that is easy to remove for cleaning or installation of a Suppressor. The FTE Muzzle Brake directs muzzle blast through ports to the sides which reduces ground blast and visual signature. This is one highly effective brake. The FTE comes bored for 22 caliber allowing it to be opened up to precisely fit your rifle. Must be fit by a qualified gunsmith.
