6310KM is the Dead Air Keymo mount version of our 6310 flash suppressor, compatible with Dead Air .30cal sound suppressors with Keymo interface.
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 5/8x24, 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. Note that since 6310KM does have flash suppression capability equal to that of an A2, it is to be treated as a flash suppressor for states that feel threatened by them, such as CA, MA and NY.
