White Label Armory A2 Flash Hider 5.56 NATO 1/2-28

The A2 birdcage is still the default muzzle device on the AR-15 and there is a reason for it. The closed bottom stops the ports from kicking dust up off the ground when you shoot prone, and the remaining slots vent gas up and to the sides to hold the muzzle down through a string of fire.

White Label Armory's version is a straight replacement cut 1/2-28 for 5.56 NATO and 223 Rem barrels. It threads onto any standard 1/2-28 muzzle with a crush washer, and the profile clears most handguards without a shim stack. If you want the classic silhouette and real flash suppression on a build, this is the part that goes on the end of the barrel.
