(R)ecoil (R)eduction (D)evice (360) Degree Ports (28)1/2-28 Threads (F)FaceMount (X37)1.375-24 External Threads
This FaceMount device is designed specifically for firearms that lack the shoulder to properly index a standard muzzle device against. This muzzle device is perfect for Kalashnikov pattern firearms with a gas block near the threads or a barrel with threads longer than 0.625" such as the 5.56 Galil ACE.
The RRD-360 Muzzle Device from JMAC Customs is unlike others on the market today. This device vents gasses 360 degrees away from your muzzle requiring less effort from the shooter to manage recoil. The use of additional, smaller ports, allows the gasses to disperse in a less concentrated pattern which reduces flash and concussion when compared to a standard muzzle brake. Due to the 360 design, this device does not require timing which makes installation much more simple and does not require shims or crush washer.
The X37 Series Muzzle Brakes combine our effective RRD muzzle brake design and a direct thread mount for several popular suppressors as well as our BDS-37 and BDS-37-EXT blast shield! This allows you to leave the muzzle device installed and simply thread the suppressor over! Reduces weight, length, and cost compared to QD systems. Direct thread is also the preferred mounting method for accuracy!
What makes the 360 unique?
Product Specs:
*When testing these devices, we found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.
This device is designed to be tightened against the face of the barrel. If timing is required, you must use our face shims (optional) or your barrel MUST be faced to properly time this muzzle device. If you're not familiar with Facemount devices, click HERE to learn more!

love these jmac brake/mounts. pulls double duty allowing you to run a brake unsuppressed and use the hub threading to mount your suppressor directly on to the muzzle device! I hope jmac dont discontinue these models, these are fantastic since your dont have to time the breaks
