The Tombstone Compensator is F-1 Firearms’ taper mounted muzzle device. Its conical face allows installation and removal to be simple while still maintaining minimal POI shift. Not only is it accurate and repeatable, but the Tombstone Compensator also has two popular threading options: 1/2x28 and 5/8x24. Additionally, this muzzle device is extremely user friendly; you don’t have to worry about any locking rings, ratcheting, or latches.
