Dead Air DA308 KeyMo Flash Hider 30 Cal 5/8x24 Black Nitride

The Dead Air DA308 KeyMo Flash Hider delivers superior muzzle flash reduction while serving as a quick-attach mounting point for Dead Air KeyMo suppressors. This precision-machined flash hider transforms standard .308 rifles into suppressor-ready platforms without sacrificing performance.

What Makes This Different

Unlike traditional flash hiders that only reduce muzzle flash, the DA308 KeyMo combines flash suppression with Dead Air's proven KeyMo mounting system. The 4140 heat-treated steel construction withstands extreme temperatures and rapid-fire schedules that destroy lesser flash hiders. Black nitride coating provides corrosion resistance superior to standard phosphate finishes while maintaining precise tolerances for consistent suppressor alignment.

Key Features

• KeyMo quick-attach system for seamless Dead Air suppressor mounting
• 4140 heat-treated alloy steel construction for maximum durability
• Black nitride finish resists corrosion and wear
• 5/8x24 RH threads fit standard .308 Winchester and 7.62 NATO rifles
• 2.70-inch overall length maintains compact profile

Field testing demonstrates consistent flash reduction across various ammunition types, from match-grade loads to military surplus. The heat-treated steel construction maintains zero shift even during extended firing sessions. Law enforcement agencies report reliable performance in low-light operations where muzzle flash concealment proves critical. Competitive shooters appreciate the ability to quickly attach suppressors between stages without tools or timing adjustments.
