Rearden R2S Flash Hider Features The Rearden R2S flash hider is machined from 17-4 PH steel and heat treated for durability under the repeated torque cycles of mounting and removing a suppressor. Its square shoulder design gives a suppressor a hard repeatable index point to seat against which keeps the can aligned consistently every time it goes on or comes off. Compatibility with Atlas Atlas XL and Plan B style mounts means it works with some of the most common quick-detach suppressor systems on the market today. At 1.74 long and 1.60 oz it adds minimal length or weight to the end of a barrel. Proper installation calls for an alignment rod to confirm the entire system is square along with cleaning all mating surfaces before torquing the device to the barrel. Rearden recommends torquing the muzzle device to roughly 15 to 25 ft lbs and the suppressor itself to about 10 ft lbs once mounted ensuring a tight repeatable seal between components. The heat-treated finish contributes to that tighter seal though it still demands careful torque and thread engagement to perform as designed. Built by a company that treats difficult engineering problems as solvable the Rearden R2S is a precision suppressor-mounting solution for sale at GrabAGun.
