The KGM Quick Detach Flash Hider in 3/4×24 muzzle index (brand part no. A-QD-FH-S-3M) is a birdcage-style muzzle device that lets a KGM suppressor mount on rifles with SR25-spec 3/4×24 threads. KGM Technologies pairs a taper mounting surface with a ratcheting secondary retention system for precise, repeatable attachment. It is machined from heat-treated chromoly steel with an OXyN gas nitride finish. It is meant for shooters who run a KGM R556, R556A1, R556A2, R30A1 or R30A2 suppressor on an SR25-pattern rifle.
