Rearden R2S Features The Rearden R2S is engineered around a 25 degree taper shoulder design that mates precisely with Plan B type suppressor mounts ensuring the device seats square against the barrel shoulder every time. Proper installation calls for an alignment rod to confirm the entire system is true along with thorough cleaning of all mating surfaces before the device is torqued and set to the barrel. Torquing the muzzle device to approximately 15 to 25 ft lbs and the suppressor to 10 ft lbs ensures the taper and threads seat correctly for a repeatable secure lockup. This attention to fitment is what allows the R2S to deliver consistent alignment shot after shot on an Atlas or Atlas XL suppressor. Machined from steel and finished in a durable nitride coating the R2S resists corrosion while creating a tighter mechanical seal between the device and the suppressor body. The 13.5x1 LH thread pattern and black finish make it a clean low profile addition to any suppressor-ready barrel built for this mount. At a compact 1.74 inches in length and only 1.80 ounces it adds negligible weight or length to the muzzle while still providing a robust mounting shoulder. Shooters running a Plan B mount setup get a precision-fit long-lasting muzzle device built for repeated suppressor attachment and removal.
