Brownells AR-308 Flash Suppressor Bottom Tap Features The Brownells AR-308 Flash Suppressor Bottom Tap is machined from high speed steel and built to cut or restore 5/8x24 threads to factory specification on AR-308 pattern barrels. High speed steel construction resists wear and heat during repeated use keeping the tap s cutting edges sharp through multiple threading jobs. Its bottom tap style is designed to cut threads all the way to the base of a blind hole which matters when a barrel s threaded section needs to be finished to full depth. Precise consistent threading like this ensures a flash suppressor or other muzzle device seats correctly and functions safely. Because the tap is cut to the same 5/8x24 specification used on AR-308 muzzle threads it restores stripped or damaged threads just as reliably as it cuts new ones on a fresh barrel. That makes it equally useful for custom barrel work and for repairing an existing rifle s muzzle threads. The tap ships as a single unit ready to use with standard tap handles and gunsmithing bench setups. For anyone threading or servicing AR-308 barrels this tap is a dependable addition to a gunsmithing toolkit.
