This can be used as a stand alone muzzle brake, but also doubles as a great suppressor mount.


The Rearden DPB is not only great as a muzzle brake, but it is also an incredible suppressor mount. The DPB gives you a taper before the threads design, which will not only help with concentricity, but this also means after hundreds of rounds, carbon won’t be on your threads. This will result in not having to worry about your suppressor getting carbon locked onto your muzzle device, and having your suppressor stuck to your gun. Rearden also added wrench flats to the back of the DPB, and includes the necessary shims to install this muzzle device. These muzzle devices will work with the Atlas, and the Atlas XL from Rearden MFG, but they are also compatible with the Plan B.


Some Suppressor Manufacturers Will Void Your Warranty If You Use A 3rd Party Mount and/or Adapter. No Matter How Good It Is.
