Threaded for 1/2x28, precision machined from solid 4130 or 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. Note that since 6315 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.Since there is now more room in front of the 3 and 9 o'clock ports, FCD incorporated wire cutter alignment notches ahead of these ports. The wire cutter notches will probably draw some flak and endless ribbing about having to cut wires at the range while punching holes on paper, but FCD has always designed combat features into their products, they cost nothing to add.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.Be considerate to fellow shooters next to you, use a flash suppressor :)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!A crush washer is included. Proudly designed and made in USA.
