Rearden Manufacturing Group Llc Prs Muzzle Brake 0.375 3/4-24 Threads Square Shoulder Black

The Rearden PRS Muzzle Brake in 0.375" with 3/4-24 threads is built for shooters running suppressor-host setups that demand precision engineering and repeatable performance. This square-shoulder brake is machined from 17-4 PH stainless steel and finished in black nitride—a treatment that creates a tighter seal and enhanced durability at the muzzle. It's designed to work with Plan B type quick-detach suppressor mounts, making it an excellent choice for hunters, long-range shooters, and tactical users who want modular sound suppression without sacrificing accuracy or reliability.

The square-shoulder design is critical: it ensures your suppressor seats consistently on the same reference surface every time you mount it, which translates to better acoustic performance and groups that stay repeatable across shooting sessions. Rearden engineered this brake for barrels larger than 0.750", but it works equally well on thinner profiles. The nitride finish isn't just cosmetic—it improves corrosion resistance and, more importantly, maintains the critical fit and seal integrity that suppressed shooting demands. Proper installation matters here: torque the brake to approximately 30 ft-lbs and secure it with a threadlocker (such as Rockset), then use an alignment rod to confirm the whole system sits true before you fire.

Compatibility with Plan B mounts opens the door to multiple silencer options from manufacturers who support that standard. This is a serious component for serious shooters—not a quick-and-easy fix, but a foundation for a precision suppressed rifle that will shoot the same every time you take it apart and reassemble it. If you're building or upgrading a suppressed hunting rifle or precision gun, the engineering and fit quality of this Rearden brake will repay your attention to detail.

Frequently Asked Questions

What suppressors work with this muzzle brake?

The Rearden PRS brake is designed for Plan B type quick-detach mounts. Any suppressor that accepts Plan B adapters will interface with this brake. Verify your suppressor or adapter ring is Plan B compatible before purchase.

What barrel sizes does this brake fit?

Rearden engineered this brake for barrels larger than 0.750" in diameter, but it will also function on thinner profiles. It features a 3/4-24 thread pitch and 0.375" bore, suitable for large magnum and specialized calibers in that class.

Do I need to use an alignment rod during installation?

Yes. Rearden strongly recommends using an alignment rod when installing this brake to ensure the entire muzzle brake and suppressor system is set up correctly and the brake sits square against the barrel shoulder.

What's the proper installation procedure?

Clean all threads and muzzle surfaces thoroughly. Torque the brake to the barrel at approximately 30 ft-lbs and secure with a threadlocker such as Rockset. Ensure the brake is square against the shoulder. When mounting a suppressor, clean the threads and tapers again, then torque the suppressor to the brake at 10 ft-lbs and confirm alignment with an alignment rod before firing.
