Rearden Mfg FHD Muzzle Device - 1/2 x 28 TPI

The Rearden FHD is a multicompatible muzzle device that fits ATLAS, ATLAS XL, and Plan B mounts.

These small mounts maximize the volume of gas behind the first baffle and provide a rock solid mount with robust threading.  Shims are not required but may be used if timing is desired.

At 2.17 oz and 1.723" length added, the FHD is a minimalist way to mitigate some flash when unsuppressed.  

Torque the muzzle device to approximately 30 ft lbs. Make sure the muzzle device is square against the shoulder. When setting the silencer on the muzzle device, ensure that the threads and tapers are clean. Torque the suppressor to 10 ft lbs. Ensure alignment. Enjoy. The nitride finish does lead to a tighter seal, with that said, it is extremely important to torque and rockset your muzzle device to the barrel properly.
