Rearden Mini Muzzle Brake Features The Rearden Mini Muzzle Brake is machined from 17-4 PH steel and treated with a black nitride finish rated to 67 HRC surface hardness giving it the durability to withstand repeated heat cycling and suppressor use. Its facemount shoulder design is built so the brake seats flush and square against the barrel shoulder a detail that matters for proper suppressor alignment and consistent accuracy. The 14x1 LH thread pattern and 0.475 bore are matched specifically to work with Atlas and Atlas XL mounting systems giving shooters a direct path to adding a suppressor without additional adapters. Rearden designed this brake specifically to integrate with their Plan B quick-attach suppressor mounting ecosystem. At just 0.97 long and 1.59 oz this mini brake adds minimal length and weight to a barrel while still providing functional recoil mitigation before a suppressor is installed. Proper installation requires an alignment rod and correct torque specifications to ensure the brake and suppressor system function safely together. Rearden notes that shims are not included so installers should plan for proper fitment during setup. For shooters building a precision rifle around the Atlas or Atlas XL suppressor mounting platform this Rearden Mini Muzzle Brake is available for sale at GrabAGun.
