The Rearden RPB 0.28 1/2-28 Square Plan B muzzle brake is purpose-built for shooters who want a compact, suppressor-ready mount that stays rock solid under hard use. Machined from durable 17-4 PH H900 stainless steel and finished in a sleek black nitride, it is designed to interface seamlessly with Plan B–style mounts while offering a clean, square shoulder for precise alignment.

This model features 1/2x28 threads with a .280 bore, making it ideal for properly threaded small-bore rifles where a secure suppressor host and effective recoil mitigation are priorities. Its short 1.74-inch length and included shims help you time the device correctly while keeping added barrel length to a minimum. Whether you are refining a range rifle or building a suppressed setup, the RPB reflects Rearden’s focus on smart engineering and consistent manufacturing quality.
