Rearden Mini Muzzle Brake Features The Rearden Mini Muzzle Brake is machined from steel and finished with a black nitride coating rated to 67 HRC surface hardness giving it excellent resistance to wear and corrosion over repeated suppressor mounting and removal cycles. A 25 degree taper shoulder ensures the device seats squarely against the barrel for consistent repeatable alignment every time it is installed. Threaded at 5/8x24 the brake is built to be compatible with both Atlas and Atlas XL adapter systems as well as Plan B mounting interfaces. Proper installation calls for an alignment rod and correct torque typically in the 15 to 25 ft lb range to ensure the entire system is set up correctly before use. At a compact 0.97 inches in length and just 1.06 ounces this mini brake adds negligible bulk to the end of a barrel while still providing a stable interface for an attached suppressor. Clean properly lubricated threads and tapers are essential when mounting a silencer to this device and the suppressor itself should be torqued to around 10 ft lbs once threaded on. Shims are not included and should be sourced separately if precise alignment adjustment is needed. The Rearden Mini Muzzle Brake is for sale at GrabAGun for shooters running Atlas or Atlas XL suppressor mounting systems who need a compact reliable taper shoulder interface.
