RISE Armament Watchman XR .22 ARC 18" Barrel Semi-Auto Rifle

The RISE Armament Watchman XR in .22 ARC delivers precision long-range performance in a compact, lightweight platform. This 18-inch barrel configuration maximizes the .22 ARC cartridge's ballistic potential while maintaining excellent maneuverability for tactical applications and precision shooting.

What Makes This Different

The Watchman XR stands apart from standard AR-15 platforms through its optimized barrel profile and enhanced trigger system specifically tuned for the .22 ARC cartridge. While conventional rifles sacrifice accuracy for portability, this configuration achieves sub-MOA accuracy potential with match-grade components throughout. The 18-inch barrel length provides the ideal balance between velocity retention and handling characteristics that longer barrels cannot match.

Key Features

• 18-inch medium contour barrel with 1:7 twist rate for optimal .22 ARC stabilization
• RISE Armament RA-434 high-performance trigger with 3.5-pound pull weight
• M-LOK compatible handguard with full-length top rail for optics mounting
• Mil-spec upper and lower receivers with Type III hard coat anodizing
• Standard AR-15 magazine compatibility with .22 ARC feeding geometry
• Adjustable gas block for suppressor use and reliability tuning
• Brown Cerakote finish for enhanced corrosion resistance

Field performance demonstrates the .22 ARC's capability to deliver 77-grain projectiles at over 2,650 fps from the 18-inch barrel, providing effective range beyond 600 yards. The cartridge excels in precision rifle competitions where wind deflection matters, while maintaining sufficient energy for medium game hunting applications. Weather sealing and corrosion-resistant coatings ensure reliable function in adverse conditions from desert heat to humid coastal environments.
