Product Description The Rearden R2 Muzzle Device is a precision-engineered flash hider and suppressor mount designed for shooters who demand reliability and performance. Built from 17-4 PH stainless steel and finished with a Black Nitride coating that delivers a surface hardness of 67 HRC, the R2 is built to withstand thousands of rounds without compromise. A signature taper ahead of the threads promotes concentricity and prevents carbon buildup on the threads, eliminating the risk of your suppressor becoming carbon-locked to your muzzle device. Compatible with the Atlas, Atlas XL, and Plan B suppressor systems, the R2 is a versatile muzzle device for serious rifle builds. Note: shims are not included; if precise timing is required, shims will be needed. Additionally, your barrel may require a shim if the manufacturer did not include a thread relief.
