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.
With the advancement of suppressor technology and the popularity of the KeyMount mounting system, the 360-28F was designed to allow users to install a KeyMount compatible muzzle device on their firearm that not only worked well, but also complemented the look of the firearm. The 360-28F is designed to sleeve over the factory barrel approximately .98" and partially cover the tri-lugs (if equipped). This allows the user to install their suppressor closer to the receiver for a shorter overall length and a better balanced firearm. In addition to a KeyMount compatible suppressor, the 360-28F is also compatible with any of our Blast Diversion Shields (BDS) in combination with the proper KeyMount adapter.
The 360-28FD will work on any barrel with 1/2-28 threads that extends a minimum of 1" beyond the handguard/gas block/front sight with a diameter less-than 0.7". Below is a list of firearms we have found to be compatible with the 360-28FD.

- *Facemount device
- *Not intended or recommend for barrels shorter than 10.5” when using rifle calibers(see below)
*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. 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!
