Product Description

Threaded for 1/2×28, precision machined from solid 4140 steel bar stock and black nitrided, 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. 6315 is compatible with M16 BFA and most A2-mounted sound suppressors.

Since FCD now has more room in front of the 3 and 9 o’clock ports, we incorporated wire cutter alignment notches ahead of these ports.

6315 is a light (2.12oz) 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. 6315 is a part of Forward Controls’ x15 muzzle device series.

Your shooting buddies will enjoy shooting next to you much more once you replace the brake or comp with something that won’t remind them of their days in artillery, that it also agitates the snowflakes is priceless.

A crush washer is included.

Proudly designed and made in USA.
