Dead Air DA301 Flash Hider 1/2x28 Thread 5.56 NATO Suppressor Mount

The Dead Air DA301 Flash Hider eliminates muzzle flash while providing a secure mounting platform for Dead Air suppressors. This precision-machined flash hider integrates seamlessly with the KeyMount system, offering shooters both standalone performance and suppressor compatibility in one component.

What Makes This Different

Unlike standard flash hiders that only reduce muzzle signature, the DA301 serves dual purposes as both a flash suppressor and suppressor mount. The proprietary KeyMount interface locks suppressors with repeatable zero retention, eliminating the need for separate mounting hardware. CNC-machined from 4140 steel with a nitride finish, it maintains dimensional stability under rapid fire conditions.

Key Features

• KeyMount compatibility with Sandman, Nomad-30, and Primal suppressors
• 1/2"-28 TPI threading for standard 5.56x45mm NATO barrels
• 2.70" overall length with optimized port geometry
• 4140 steel construction with salt bath nitride finish
• Eliminates muzzle flash in low-light conditions
• Maintains zero when mounting/unmounting suppressors
• Compatible with standard A2 sight picture

Field testing demonstrates consistent flash reduction across various ammunition types, from M193 ball to heavier match loads. The three-prong design effectively disperses combusting gases while the KeyMount taper ensures solid lockup under recoil. Law enforcement agencies report reliable performance in urban environments where muzzle signature matters. Competition shooters appreciate the ability to quickly attach suppressors between stages without losing zero.
