Dead Air DA307 KeyMo Flash Hider 30 Cal 5/8x24 Black Nitride

The Dead Air DA307 KeyMo Flash Hider delivers superior muzzle flash reduction while serving as a quick-detach mounting platform for KeyMo-compatible suppressors. This precision-machined flash hider eliminates the bright signature that compromises shooter position during low-light operations.

What Makes This Different

The DA307 combines effective flash suppression with the versatility of Dead Air's KeyMo mounting system in a single component. Unlike standard flash hiders that only reduce muzzle flash, this unit provides a secure suppressor attachment point without requiring additional adapters or tools. The 4140 heat-treated alloy steel construction withstands sustained rapid fire while maintaining precise timing and zero retention.

Key Features

• KeyMo quick-detach system compatible with Dead Air Sandman series suppressors
• 4140 HT alloy steel construction with black nitride finish for corrosion resistance
• 5/8x24 right-hand threads fit standard .30 caliber barrels
• 2.70-inch overall length provides optimal flash reduction without excessive length
• Closed-tine design eliminates snagging on gear or vegetation
• Precision timing ensures proper suppressor alignment and barrel clearance
• Black nitride finish reduces glare and provides long-term durability

Field testing demonstrates consistent flash reduction across multiple .30 caliber cartridges, from .308 Winchester to .300 Blackout. The closed-tine configuration prevents debris accumulation while maintaining structural integrity under rapid fire conditions. Suppressor attachment requires no tools and locks securely with audible confirmation of proper engagement.
