Rearden SPB 5/8X24 Muzzle Device, Black Nitride (10007)

The Rearden SPB is not only great as a muzzle brake, but it is also an incredible suppressor mount.

The SPB gives you a taper before the threads, 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 SPB, 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.
