Forward Controls Design 6310AE Compensator – Allen Engineering – 5/8×24

6310AE is a collaboration between Allen Engineering and FCD. Threaded for 5/8 x 24 (internal) and M22 x 1 (external), 6310AE is compatible with Allen Engineering 30 sound suppressors, such as AEM5-30 and AEM5-30K.

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.

To our knowledge, Ops Inc never produced a flash suppressor for 30 cal sound suppressors, which makes 6310AE the first AE suppressor compatible flash suppressor.

6310AE is a 6310 (introduced in 2017) that’s been designed to accept Allen Engineering 30 cal sound suppressors. 6310 itself is based on the TDP A2 compensator, 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. Flats are incorporated for standard AR15/M16 armorer’s wrench, or 3/4″ wrench for installation.
