The LBE Unlimited Three Prong Flash Hider (LBE part no. ARFH3PNG) is a 1/2-28 threaded muzzle device built for 5.56x45mm NATO AR-15 barrels. LBE machines it from 1215 steel and finishes it black, using a classic three-prong design that breaks up muzzle gas to cut down visible flash signature compared to a plain barrel. It ships with a properly sized 5.56 crush washer, so the whole assembly torques down and times correctly on a standard mil-spec 1/2-28 threaded barrel. Installation calls for a 3/4-inch wrench, making it a straightforward swap for a shooter upgrading from a bare threaded barrel or a worn factory device.
