Forward Controls Design 6315KM-L 5.56 Extended Flash Hider

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).

Threaded for 1/2×28 and precision machined from solid 4140 steel bar stock. It is both heat treated and QPQ coated. 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 5.56mm sound suppressors.  Note that since 6315KM -L 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.

6315KM-L is a light, blended performance muzzle device. It provides 15 to 20% better muzzle rise compensation than the A2.
