*Shims kit not included.


The KeyMo muzzle device was strategically designed for ultimate tactical performance; it accomplishes muzzle rise compensation without excess noise or a reduction of flash suppression. These features may support improved accuracy by improving your handling of your AR-15.

This device was engineered to exceed the performance of an A2 compensator. The 6315KM offers approximately 15-20% compensation against muzzle rise in comparison to the A2.

Forward Controls named this device 6315KM after the Stoner 63 machine gun, which inspired its design.

Tactical Features and Durability in Design

Forward Controls understands the importance of providing a durable product that you can confidently rely upon. Therefore, their KeyMo muzzle device is manufactured from machined 4140 heat-treated, black nitrided steel bar stock.

Famous for including tactical combat features, Forward Controls does not disappoint with this muzzle device; wire cutter alignment notches are located above the 3:00 and 9:00 ports should you need to utilize them.

This device features wrench flats on the barrel to support the torquing that occurs during installation or adjustments. For installation, you will need either an armorer's wrench, a 3/4 wrench, or a Joint Muzzle Device Wrench. Screwdrivers should not be used as they will cause damage to the muzzle device.
