Forward Controls Design Keymo Suppressor Mount For Dead Air Suppressors 5/8''X24

The Forward Controls Design Keymo suppressor mount for Dead Air suppressors in 5/8"x24 threading gives you a precision quick-detach interface built on decades of muzzle device expertise. This mount is engineered to work seamlessly with Dead Air's 30-caliber suppressor line, combining the speed and repeatability of Keymo's quick-attach system with FCD's reputation for tight tolerances and American manufacturing. Whether you're setting up a precision rifle, a dedicated .308, or a magnum-class hunting gun, this mount lets you swap your suppressor on and off without tools while maintaining zero.

Machined from solid 4140 steel and treated with QPQ finish for corrosion resistance, the 6310KM is a compact, lightweight muzzle device that doesn't sacrifice performance. Its design features shorter and narrower ports at the 3 and 9 o'clock positions that funnel gas upward, providing approximately 15–20% better recoil control than the classic A2 compensator while maintaining A2-level flash suppression. That's the engineering philosophy behind it: better handling without additional noise or concussion. The Stoner 63 light machine gun's flash suppressor inspired its porting geometry, and the "KM" in its name signals the Dead Air Keymo interface.

Each mount ships with a crush washer and is proudly made in the USA. FCD's attention to detail—from the heat-treating process to the final machining—means this is a mount that will hold zero, cycle reliably, and last through years of hard use.
