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).
Precision machined from solid 4130 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 we now have more room in front of the 3 and 9 o'clock ports, we incorporated wire cutter alignment notches ahead of these ports. The wire cutter notches will probably earn us some flak and endless ribbing about having to cut wires at the range while punching holes on paper, but we always design combat features into our products, they're there, you don't have to use them :)
6315 is a light and short blended performance muzzle device. It provides 20 to 25% 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.
Be considerate to fellow shooters next to you, use a flash suppressor :)
For every 6315 we sell, we will donate a portion of the profit to President Trump's 2020 re-election campaign (we're still getting calls and emails asking for money from the times we donated to them with the DEPLORABLE patch proceeds), and post the receipts here. Flash suppressors are evil and scary, and "nobody needs it for hunting." But really, 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 field artillery, that it also agitates the snowflakes is priceless.
A crush washer is included. Optional Precision Armament 1/2x28 Accu-Washer is available (please see drop down menu).
NOTE: Tolerance stacking might prevent Griffin Armament's M4SD sound suppressors from working with the 6315.
Proudly designed and made in USA.
