Gemtech ETM Flash Hider 1/2-28, Black - Superior Flash Suppression - 13815

Gemtech ETM Flash Hider - LowFlash ETMCompatible Muzzle Device for .223 Rem / 5.56 NATOThe Gemtech ETM Flash Hider is a precisionmachined muzzle device engineered to suppress visible flash on .223 Rem / 5.56 NATO rifles while preserving a short, lowprofile stack. Threaded 1/2x28 for direct fitment to common 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 lowlight conditions, improve followup recovery, and reduce visible signature that can reveal a shooter's position. Designed to integrate with Gemtech's ETM quickattach ecosystem, the flash hider provides repeatable, toolsimple 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.
