The popular Phantom Flash Suppressor has been redesigned to work with your .308 rifle as a muzzle compensator while maintaining the excellent flash hiding capabilities of its predecessor. This 5 port design has no downward facing port which helps eliminate dust problems when shooting in the prone position. The 5C2 retains the aggressive front end for use in hand-to-hand situations. For threaded barrels only. Includes crush washer. For barrels threaded with 5/8"-24 only. Includes crush washer.
