The Griffin Explorr 300 Taper Mount AM FDE is the flat dark earth version of Griffin Armament’s 3D-printed .30 caliber Taper Mount suppressor (Griffin part no. GAET3FDEAM-W). Griffin prints the baffle core in Nickel 625X, a proprietary alloy built for strength at high temperature. Its ECO-FLOW baffles reduce backpressure, and the integrated flash hider end cap keeps muzzle signature down. The integrated Taper Mount keeps point of impact shift minimal. It is a strong match for a .300 Blackout build, though Griffin rates it all the way to .300 Win Mag.
