The Forward Controls Design AR .308 6315 flash hider for Keymo mount is a precision-engineered muzzle device built for shooters running Dead Air suppressors on their .308 rifles. Machined from 4140 steel and heat-treated with QPQ finish, this compact flash suppressor threads on at 5/8x24 and interfaces directly with Dead Air's Keymo suppressor system, giving you a rock-solid connection that's fast to attach and remove. If you're serious about modular rifle setups, this is the kind of detail that separates a pieced-together gun from one that works like it was designed that way.
The design philosophy here pulls from the Stoner 63 light machine gun—you'll notice that in the port geometry. The 3 and 9 o'clock side ports are intentionally smaller than the three upward-facing ports, which routes more gas toward the top of the muzzle. That asymmetric approach actually gives you 15 to 20% better muzzle rise compensation compared to an A2-style flash hider, all without adding noise or concussion that'd make your shooting buddies hate you. The flash suppression itself is on par with an A2, which means in low-light situations or tactical scenarios, you keep your signature minimal.
This is a light, short device—no unnecessary bulk on your barrel. It's made in the USA and comes with a crush washer for installation. Whether you're setting up a precision .308 for long-range work, a hunting rifle, or a duty gun, the 6315 gives you the suppressor compatibility and recoil management you're paying for without compromise.

Yes, the 6315 is designed for Dead Air 5.56mm sound suppressors and uses the Dead Air Keymo mounting system. The Keymo interface allows quick attachment and removal of your suppressor.
The 6315 is threaded for 5/8x24, the standard pitch for .308 AR platforms. A crush washer is included with the device.
The 6315's asymmetric port design provides 15 to 20% better muzzle rise compensation than a standard A2 flash hider, while maintaining equivalent flash suppression and without increasing noise or concussion.
The 6315 has flash suppression capability equivalent to an A2 flash hider. Since it suppresses flash, it should be treated as a flash suppressor in jurisdictions with restrictions (such as California, Massachusetts, and New York). Always verify local and state laws before purchase.
