The Battle Arms Development WORKHORSE Upper Receiver Assembly in 5.56x45mm NATO is engineered for precision and reliability in AR-15 platforms, delivering a complete 10.5" carbine-length upper with an anodized black finish that stands up to field use. This compact upper pairs a 10.5" barrel with a carbine-length gas system to balance maneuverability and consistent cycling, while the A2 flash hider helps manage muzzle rise and blast signature for closer-range engagements. The WORKHORSE 9.5" M-LOK Free Float Handguard provides versatile accessory attachment without sacrificing rigidity, giving shooters a clean platform for optics, lights, and grips. Note that the upper ships without a bolt carrier group or charging handle, allowing you to pair your preferred BCG and CH for optimized compatibility with your existing components. Built to fit AR-15 receivers, this upper assembly emphasizes a robust anodized finish and a streamlined profile that suits duty, sport, and tactical prep scenarios. Whether youre upgrading a build or completing a turnkey rifle, the WH-UR-10.5-556 upper from Battle Arms Development combines proven reliability with practical dimensions, enabling rapid deployment, easy maintenance, and precise performance across 5.56 NATO engagements.
