Rearden PRS Features The Rearden PRS is a suppressor-ready muzzle device manufactured from 17-4 PH stainless steel in the H900 heat treated condition providing the strength and hardness needed for consistent Atlas-style suppressor interface performance across sustained use on compatible rifle platforms. The 3/4x20 thread pitch with .375 bore size is specifically suited to large-profile barrels commonly found on precision rifles and heavy-contour hunting platforms making the PRS a versatile suppressor-ready muzzle device for shooters running Atlas Atlas XL and Plan B compatible suppressor systems on larger-diameter barrel profiles. An Atlas adapter overrun of approximately 1.050 applies with standard Atlas adapters while the Atlas XL adapter produces no overrun for the most compact suppressor package possible. The black nitride 3/4x20 suppressor-ready muzzle device is finished with a nitride surface treatment that delivers superior hardness corrosion resistance and a consistent black appearance that holds up to sustained heat cycles and repeated suppressor attachment and detachment cycles without degradation. Recommended installation torque of approximately 30 ft-lbs on the muzzle device and 10 ft-lbs on the suppressor ensures proper engagement and consistent suppressor interface performance and shims are not included with the 3/4x20 configuration so proper timing should be verified during installation. Proper alignment verification is essential for optimal function and consulting a qualified gunsmith is recommended if needed.
