6315KM-L (long) is the Dead Air sound suppressor Keymo mount of our 6315 (1/2×28) flash suppressor designed for 13.9″ barrels, compatible with .223 Dead Air sound suppressors with Keymo interface. 6315KM-L is 2.7″ long, and can bring a 13.9″ barrel to non-NFA length (16.1″, assuming 0.5″ of threading on the barrel)
We are a big fan of the A2 flash suppressor / compensator (compensator is the Army TM 9-1005-319-23&P, Air Force TO 11W3-5-5-42, Navy SW370-BU-MMI-010 designation). It is inexpensive, and does a decent job of what’s asked of it. We went through a phase of expensive and fancy brakes and comps, all of them have worked well but we know they’re not practical for defense/duty ARs. The flash, noise and concussion they produce are the result and byproduct of reducing the felt recoil (brakes) and keeping the muzzle down (comps).
Threaded for 5/8×24, 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-L is compatible with Dead Air sound suppressors.
