The 6315KM is the Dead Air sound suppressor Keymo mount of our 6315 (1/2x28) flash suppressor, compatible with .223 Dead Air sound suppressors with Keymo interface. Threaded for 1/2x28, precision machined from solid 4140 steel bar stock, heat treated and QPQ coated, it is probably the finest A2 style comp/flash suppressor ever produced. Its 3 and 9 o'clock ports are 25% smaller (shorter and narrower) than the other three upward facing ports so more gas is vented through the upward facing ports, it is a superior compensator to the A2, its flash suppression is equal to that of an A2. 6315KM is compatible with Dead Air 5.56mm sound suppressors. Since we now have more room in front of the 3 and 9 o'clock ports, we incorporated wire cutter alignment notches ahead of these ports. 6315KM is a light and short blended performance muzzle device. It provides 15 to 20% better muzzle rise compensation than the A2, and what is impressive is that it does so without sacrificing its flash suppression capabilities, or creating more noise and concussion. The number 63 in its name pays homage to the Stoner 63 light machine gun, the shape of its ports draws heavily from the Stoner 63 LMG's flash suppressor design.
