The RISE Armament Watchman XR 6 ARC delivers precision shooting capabilities in a lightweight platform optimized for long-range accuracy. This 18-inch barreled upper receiver assembly combines advanced materials with proven ballistics to extend effective range beyond traditional AR-15 configurations.
What Makes This Different
The 6mm ARC chambering provides superior ballistic coefficient compared to 5.56 NATO, maintaining velocity and energy at extended distances. RISE Armament's proprietary barrel profile reduces weight while maintaining rigidity, resulting in consistent accuracy across temperature variations. The Watchman XR platform incorporates a low-profile gas block and enhanced bolt carrier group engineered specifically for the 6 ARC cartridge's pressure curve.Key Features
