The 6310KM is the Dead Air Keymo mount version of our 6310 flash suppressor, compatible with Dead Air .30cal sound suppressors with Keymo interface. Threaded for 5/8x24, precision machined from solid 4140 steel bar stock, heat treated and QPQ treated, 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 superior to that of a longer factory A2 style flash suppressor. 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. 6310KM is a light and short blended performance muzzle device. It provides 20 to 25% 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.
