Dead Air SCAR Flash Hider

The FN SCAR's biggest muzzle-device headache is its barrel shoulder. The SCAR 17 and SCAR 16 use a thin barrel with a small shoulder, and most muzzle brakes and flash hiders bottom out against the crown before the threads ever seat against that shoulder. The result is a device that times wrong, sits crooked, or refuses to torque. The Dead Air SCAR flash hider is cut specifically to index off the muzzle crown instead of the shoulder, which is what makes it sit correctly on a SCAR without a shim kit or an aftermarket shoulder ring.

The DA305 is the 5/8x24 version for the 7.62 SCAR 17, and the DA306 is the 1/2x28 version for the 5.56 SCAR 16. Both double as a mounting interface for Dead Air's KeyMo quick-detach suppressors, including the Sandman-L, Sandman-S, Sandman-K, and the KeyMo-equipped Nomad-30, so a SCAR owner running a compatible Dead Air can on the rifle gets a flash hider and a suppressor mount in one part. Street price runs around $85 to $94 depending on retailer and thread pitch.
