Rise Armament WatchmanXR Complete AR-15 Upper Receiver - 6mm ARC - 18" - Patriot Brown

The Rise Armament WatchmanXR Complete AR-15 Upper Receiver in Patriot Brown pairs an 18" fluted stainless barrel chambered in 6mm ARC with a skeletonized free-float handguard, built for long-range accuracy without excess weight.

Features:

• 18" fluted stainless steel barrel, button rifled, 11-degree target crown
• Chambered in 6mm ARC, 1/2x28 threaded muzzle
• Pinned low-profile gas block
• 15.25" free-floating skeletonized aluminum handguard
• Patent-pending handguard attachment lock for zero retention
• RISE ambidextrous charging handle
• Forged aluminum upper receiver
• Cerakote Patriot Brown finish with black accents

Fluting the barrel cuts weight without sacrificing the rigidity a precision 18" build needs, and the 11-degree target crown protects the muzzle's rifling from dings that can throw off accuracy. The handguard's patent-pending attachment lock keeps zero consistent even after removing and reinstalling accessories, and its skeletonized, snag-free front profile shaves further weight from the front end.

Rise Armament designs its AR-15 components for shooters who want measurable accuracy gains over stock parts, backing this WatchmanXR upper with the same attention to detail across its full product line. The ambidextrous charging handle ensures equally convenient operation whether you shoot right- or left-handed, and the whole upper installs on any mil-spec AR-15 lower without modification, giving 6mm ARC shooters a ready-to-mount long-range option.
