The Silent Steel USA BoltLok Flash Hider for 7.62/.308 (brand part no. FHAQDL-B-762-58X24) is a dual-purpose muzzle device that doubles as the quick-detach mounting point for Silent Steel USA’s BoltLok suppressor system. Threaded 5/8×24 for standard .308/7.62 barrels, this flash hider stays on the rifle full-time, tames muzzle flash for unsuppressed shooting, and lets a compatible Silent Steel USA suppressor lock on and off in seconds without losing zero. Among our silencers and suppressed firearms, this flash hider suits .308/7.62 shooters building toward a quick-attach suppressed setup on their existing rifle.
