Carbine Muzzle Brake Suppressors

This suppressor has been a production item, with improvements, since 1987. The device attaches directly to the .5"-28 TPI barrel thread and protrudes past the end of the barrel 5 inches and goes back over the barrel to a point in front of the bayonet lug. A barrel fitting that attaches to the barrel near the front sight assembly, this is used in conjunction with the threaded muzzle to align and secure the device to the weapon. Once the barrel fitting is installed, no tools are required to remove or install the MBS to the weapon. The 24 oz weight of the device is offset by 2 oz totaling a 22oz gain. The weight offset is due to the flash hider being removed from the weapon.
