Allen Engineering/FCD Flash Hider 1/2-28

6315AE and 6310AE are a collaboration between Allen Engineering and Forward Controls Design.  Threaded for 1/2 x 28 (internal) and M22 x 1 (external), 6315AE is compatible with all Allen Engineering/ OPS INC sound suppressors utilizing a muzzle device.

Most folks are familiar with the iconic Mk12 brake.  We’re a big fan of the brake, it’s one of the least obnoxious brakes we tested, our own 1215KM (Keymo), 1215XE (Xeno), 1215RF (Plan B compatible) are based on the Mk12 brake design.

While the Mk12 brake is well known, OPS INC. at the time also made flash suppressors in 3 prong and A2 form factor, we’ve also seen a version that appears to be a shortened Smith Enterprises Vortex, as well as a large diameter 3 prong flash suppressor that threads on the Mk12 brake.

6315AE/6310AE are a 6315 (introduced in 2017) that’s been designed to accept Allen Engineering sound suppressors.  6315 itself is based on the TDP A2 compensator (Army 23&P designation), and features smaller 3 and 9 o’clock ports which force more gas to be vented through the top 3 ports.  Throughout the years, we’ve added small improvements to it, the most notable is the internal grooves that help keep the flash inside the cone cavity, instead of outside of the muzzle device.
