Rearden Manufacturing Group Llc Mini Muzzle Brake 0.456 1/2X36 Thread Square Shoulder Black

The Rearden Mini Muzzle Brake is a precision-engineered adapter designed to interface your suppressor with modern quick-detach systems. Built from 17-4 PH stainless steel in the H900 condition and finished with black nitride for durability and corrosion resistance, this 0.456-bore, 1/2×36 threaded brake serves as the foundation of a reliable suppressor mounting solution. Whether you're running an Atlas, Atlas XL, or Plan B suppressor, this square-shoulder brake ensures consistent alignment and repeatable attachment—critical for both accuracy and sound mitigation.

Rearden designed the Mini to minimize footprint without sacrificing rigidity. The 0.456 bore accommodates standard rifle calibers, while the square shoulder seats flush against your barrel for solid, repeatable positioning. The black nitride finish—hardened to 67 HRC—resists carbon buildup and maintains its finish through years of suppressor removal and remounting. Installation requires attention to detail: torque the brake to your barrel at 15–25 ft-lbs and ensure it sits square; clean threads and tapers before mounting your can; then torque the suppressor itself to 10 ft-lbs and verify alignment with an alignment rod.

This is a no-frills, no-compromise component for shooters who demand precision in their suppressor system. If you're building a dedicated rifle or replacing a worn muzzle device, the Rearden Mini pairs with proven Rearden suppressors and other compatible systems to give you a rock-solid platform for the field, range, or PRS competition.
