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 X20 Series Muzzle Brakes combine our effective 360 muzzle brake design and a direct thread mount for several popular suppressors as well as our BDS-20 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!
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.
***JMac Customs is NOT responsible for improper installation of this muzzle device or any damage to the suppressor using this device. We recommend this be professionally installed and checked to ensure alignment.***
JMac Customs recommends that all suppressor mounts be installed and checked for alignment by a certified professional. Serious damage could result to your suppressor/firearm and physical harm is possible if installed/used incorrectly. All suppressor mounts MUST be tight against the shoulder or face of the barrel, using shims or face-milling method. Contact us if you have any questions or need a recommendation for professional installation. JMac Customs LLC is not liable for injury, damage, or death related to the usage of this product.
I just have a PSA 300 BO 7.5” I put this on and man it sits just perfectly flush with the end of the hand guard. Locks up tight to the shoulder and gives the silencer a seemless transition look from end of barrel/hand guard to Wolfman. It also looks just rugged, strong and cool without the suppressor. Jmac does it again!
