Gemtech 7.62 ETM Flash Hider - Low-Flash ETM-Compatible Muzzle Device The Gemtech 7.62 ETM Flash Hider is a precision-machined muzzle device engineered to suppress visible flash on 7.62 NATO/.308 Winchester rifles while preserving a short, low-profile stack. Threaded 5/8A-24 for direct fitment to common 7.62 muzzles, the unit is finished in durable black nitride for corrosion and erosion resistance and built to withstand repeated service. Tuned porting disperses gas away from the bore axis to protect sight picture in low-light conditions, improve follow-up recovery, and reduce visible signature that can reveal a shooter's position. Designed to integrate with Gemtech's ETM quick-attach system, the flash hider provides repeatable, tool-simple engagement when paired with compatible ETM adapters and suppressors, while remaining effective as a standalone muzzle device. Install with standard tools, verify correct thread fit, and visually confirm baffle alignment and secure engagement before firing.
