Rearden R2 Features The Rearden R2 Flash Hider is built to fit Plan B type suppressor mounts giving shooters a secure repeatable interface compatible with Atlas and Atlas XL adapter systems. Proper installation calls for an alignment rod to verify the system is correctly set up with the device torqued to approximately 30 ft lbs and the muzzle device squared against the shoulder before suppressor attachment. Machined from 17-4 PH steel the R2 is built to withstand the repeated torque and removal cycles that come with mounting and dismounting a suppressor. A square shoulder design ensures consistent alignment every time the suppressor is installed. Finished in black nitride rated to 67 HRC surface hardness the R2 resists wear from repeated use while helping create a tighter seal between the flash hider and the suppressor. When setting the suppressor onto the device Rearden recommends ensuring the threads and tapers are clean for a proper aligned fit then torquing the suppressor to 10 ft lbs. At 2.23 inches long and weighing just 1.9 ounces the R2 adds minimal length and weight to a rifle while delivering reliable flash suppression and suppressor mounting performance. For shooters running a Plan B compatible suppressor system with 5/8x24 threading the Rearden R2 is available for sale at GrabAGun.
