Most Recent Reviews Jmac 360 on criterion barrel 5.56 by Fullbach, Verified Owner, April 26, 2025
I mounted this on my 12.5 5.56 ar with a criterion barrel. You do have to time these breaks so the ports are in the correct position to reduce recoil. Fortunately that’s pretty easy, then add a little rock set and you’re ready to attach your hub comp...

Product Info for JMac Customs RRD-360-28F-X37 FaceMount

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 0.625in 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!image
