Dead Air Keymount Flash Hider - Black, 5/8x24 Threads

The Dead Air Keymount Flash Hider in 5/8x24 threads is a purpose-built muzzle brake designed to work seamlessly with Dead Air Silencers' suppressor lineup. If you're running a Sandman suppressor and want flash reduction without the acoustic signature issues that plague many combo setups, this is the match you've been looking for. The Keymount platform lets you swap between suppressors and flash hiders on the same barrel-mounted interface, giving you flexibility for different hunting and shooting scenarios.

What sets this flash hider apart is its patent-pending design with mass-shifted, equal-length tines. That engineering choice eliminates the metallic "ping" that occurs when firing through many traditional flash hiders paired with cans—a problem shooters know all too well. The tine geometry is tuned specifically for Dead Air suppressors, so you get optimized flash reduction and a cleaner shooting experience on the range or in the field.

Built in black for durability and aesthetics, the Keymount Flash Hider weighs between 3.6 and 4.0 ounces and extends 2.7 inches from the muzzle. The 5/8x24 thread pitch accommodates a wide variety of modern rifles. A lifetime warranty backs the unit, giving you confidence in the purchase.

Frequently Asked Questions

Will this flash hider work with suppressors other than Dead Air?

This flash hider is designed and optimized for Dead Air Silencers suppressors. While the 5/8x24 thread pitch is standard across many modern rifles, the patent-pending tine geometry is engineered specifically to eliminate the "ping" that can occur with Dead Air cans. Compatibility with other suppressor brands is not covered in the product specifications.

What rifles does the 5/8x24 thread pitch fit?

The 5/8x24 thread pitch is common on modern rifle platforms, particularly .308 Winchester and 6.5 Creedmoor rifles, as well as many AR-platform guns in larger calibers. Verify that your barrel is threaded to 5/8x24 before purchase—incorrect thread pitch can damage your rifle and the hider.

Can I swap between the Keymount Flash Hider and a Keymount suppressor?

Yes. The Keymount platform allows you to rotate between Dead Air suppressors and flash hiders on the same barrel-mounted interface, provided they share the Keymount design. This flexibility is one of the system's key advantages for shooters who want to customize their setup.

What makes this flash hider different from standard designs?

The patent-pending tine design uses mass-shifted, equal-length tines. This geometry is engineered to prevent the metallic ringing ("ping") that commonly occurs when firing a suppressor paired with a traditional flash hider—a problem Dead Air heard from its customers and addressed with this product.
