Rearden PRS .308 Muzzle Brake - Plan B - 5/8x24 - Square Shoulder - Black Nitride

The Rearden PRS Muzzle Brake pairs recoil-reducing ports with a built-in Plan B suppressor mount in a black nitride finish, for owners who want one device for recoil control and quick-detach suppressor attachment.

Features:

• Recoil-reducing brake with a built-in Plan B suppressor mount
• Threaded 5/8x24 for direct installation onto a matching barrel
• .375-inch bore clears calibers up to .338 Lapua and 9mm
• Square-shoulder design for barrels with a traditional 90-degree shoulder
• Black nitride finish for surface hardness and corrosion resistance
• Precision-machined for a repeatable Plan B taper fit
• Plan B taper mount, also compatible with Rearden Atlas and Atlas XL adapters

This square-shoulder version is meant for barrels with a flat shoulder behind the threads, so make sure it seats flat and square against the shoulder before you torque it down, and keep the threads and tapers clean.

Rearden's Plan B instructions call for cleaning all surfaces, using an alignment rod whenever a suppressor goes on a Plan B-type taper mount, and torquing the muzzle device with a thread locker such as Rocksett, then the suppressor to about 10 ft-lbs. Nitride gives a tighter seal, so proper torque matters. Check your suppressor maker's warranty terms before pairing.

Rearden builds Plan B muzzle devices as the mounting point for Plan B-compatible adapters. With a Rearden Atlas adapter (sold separately), they fit most suppressors that use a 1.375x24 rear thread.
