note the comp i put on end of my barrel , almost zero flash from muzzle. had to grind off 1 small weld with a dremel and remove the barrel nut on threads , screws right on , lock threaded her and shoots great , hardly any flash or recoil for a .308 cal rifle very low recoil with that comp i am using from natchez. Almost nil flash in daylight. im sure there is some flash at night but with the comp i am using i have not seen much of a flash at all from my M77 pap serbian .308 ak. Zombies lol, never happen .Do love the show walking dead but never happen in my lifetime at least i sure hope not we could not win that fight.
