The Rearden PRS muzzle brake in 0.280 caliber with 1/2-28 threads is purpose-built for precision rifle shooters running suppressor-ready setups. Machined from 17-4 PH stainless steel and finished in black nitride, this square-shoulder brake is engineered to work seamlessly with Plan B type suppressor mounts and Atlas adapters—the core hardware of modern PRS (Precision Rifle Series) builds. If you're threading a 0.280 barrel and want a repeatable, compatible platform for mounting a can, this is the foundation you need.
The square-shoulder design ensures the brake seats consistently against your barrel shoulder, critical for maintaining zero and suppressor alignment shot after shot. Black nitride finish provides durability and corrosion resistance while tightening the seal between brake and barrel—though that finish also demands careful installation: clean surfaces, proper torque (approximately 30 ft-lbs), and Rockset threadlocker are not optional steps. The brake is designed for barrels larger than 0.750" in diameter but will function on smaller profiles as well.
Rearden engineered this brake to be compatible with both standard Atlas and Atlas XL suppressor adapters, giving you flexibility in your can choice. When you thread a suppressor onto the brake, clean threads and taper surfaces, then torque to 10 ft-lbs and verify alignment with an alignment rod before firing. This is precision equipment; it rewards careful setup with reliable performance downrange.

The brake is engineered for barrels larger than 0.750" in diameter but will function on smaller profiles as well. Confirm your barrel profile before ordering.
Clean all threads and the shoulder thoroughly. Thread the brake onto the barrel, seat it against the shoulder, and torque to approximately 30 ft-lbs. Apply Rockset threadlocker for security. Use an alignment rod to verify the system is square before firing. When mounting a suppressor, clean threads and taper surfaces, torque to 10 ft-lbs, and verify alignment.
