Dead Air Armament Da307 Keymo Fh Fal 9/16X24 Lh

The Dead Air Armament DA307 KeyMo flash hider is a precision-engineered muzzle device built specifically for FAL rifles and other firearms with 9/16x24 left-hand threads. This flash hider integrates seamlessly with Dead Air's KeyMo suppressor mounting system, letting you run a Sandman Series suppressor or other KeyMo-compatible can on your rifle while maintaining the freedom to remove and remount without worrying about carbon lock-up—a real advantage when you're cycling equipment between firearms or need fast suppressor changes in the field.

Dead Air engineered this flash hider with a distinctive design: equal-length tines positioned to shift mass in a way that eliminates the characteristic "ping" common to conventional flash hiders. That matters if you're hunting or shooting in noise-sensitive environments where audible feedback from the muzzle device itself can give away your position. The construction is 4140 heat-treated alloy steel with a durable black nitride finish, built to withstand the rigors of repeated mounting cycles and hard use.

This particular model comes drilled and ready for pin-and-weld installation if your local regulations or rifle setup require a permanently fixed muzzle device. Whether you're suppressing a semi-auto FAL for tactical training, hunting, or range work, the DA307 gives you a rock-solid KeyMo platform that won't let you down.

What rifles does the 9/16x24 left-hand thread pattern fit?

Yes. The DA307 comes with a pre-drilled pin-and-weld hole at the 6 o'clock position, making it ready for permanent installation if required or desired.

Why does this flash hider design not "ping"?

Dead Air's equal-length tine design with mass shifted proportionally reduces the vibration and audible feedback that traditional flash hiders produce, resulting in a notably quieter muzzle device.
