Rearden Prs Mb .375 5/8-24 Nitride

The Rearden PRS muzzle brake in .375 caliber with 5/8-24 threads and nitride finish is purpose-built for shooters running suppressor-ready setups on larger magnum rifles. This is a dedicated muzzle device designed to work with Plan B quick-detach suppressor mounts and Atlas/Atlas XL adapter systems, giving you a modular solution that keeps your rifle balanced and your workflow efficient whether you're on the range or hunting big game.

Built from 17-4 PH H900 stainless steel and finished in black nitride, this brake is engineered for durability and repeatability. The nitride finish creates a tighter seal when mated to your barrel and suppressor, which is why proper installation—torquing to spec and locking everything down with Rocksett—matters. Rearden designed this for barrels larger than .750" in diameter, though it will function on lighter profiles too. The compact footprint means you're not adding unnecessary length to your rifle while still maintaining full brake functionality and suppressor compatibility.

If you're building a .375 magnum rifle around a suppressor and Plan B mount ecosystem, this brake gives you the precision interface you need. Just remember: use an alignment rod during installation to ensure the entire system runs true, keep your threads and tapers clean, and follow the torque specs—30 ft-lbs on the brake itself, 10 ft-lbs on the suppressor. This is the kind of detail work that separates a quiet, accurate rifle from an expensive paperweight.

Specifications

Frequently Asked Questions

Is this muzzle brake compatible with Plan B suppressor mounts?

Yes. This brake is designed specifically for Plan B quick-detach mounts and works with Atlas and Atlas XL adapter systems. Always use an alignment rod during installation to ensure the threads and tapers are square and true.

What barrel diameter does this fit?

It's designed for barrels .750" and larger, but will function on smaller profiles as well. The key is ensuring proper torque and Rocksett application for a secure, sealed installation.

Will using this brake with a suppressor void my warranty?

Check with the suppressor manufacturer on their warranty terms. Some suppressors have specific muzzle device compatibility requirements. Rearden recommends cleaning all threads and tapers and following proper torque specs (30 ft-lbs on the brake, 10 ft-lbs on the suppressor) for optimal performance and seal integrity.

Are shims or adapters included?

Shims are not included with the 5/8-24 model. Check compatibility with your specific Atlas or Atlas XL adapter setup to confirm any additional components you may need.
