The Griffin Explorr 300 Taper Mount AM Black is Griffin Armament’s additively manufactured .30 caliber suppressor with an integrated Taper Mount (Griffin part no. GAET3AM-W). Its core is built from Griffin’s Nickel 625X powder alloy and laser welded to a machined rear. ECO-FLOW backpressure-reducing baffles mean less system wear on a gas-operated rifle, and an integrated flash hider end cap trims flash. The Taper Mount interface gives an accurate lockup with minimal point of impact shift. It covers a .300 Blackout carbine, a .308 hunting rifle and magnums up to .300 Win Mag.
