Overview

The Battle Arms Development WORKHORSE complete upper receiver is engineered for the AR-15 platform. Chambered in 5.56 NATO, this assembly includes a 10.5-inch barrel crafted from 4150 chrome-moly steel with a black nitride finish for enhanced durability and corrosion resistance. The receiver itself is forged from 7075-T6 aircraft-grade aluminum and is finished in black anodizing. This upper features a free-float M-LOK handguard with attachment points at the 3, 6, and 9 o'clock positions and a full-length Picatinny rail at 12 o'clock. The assembly is equipped with an ambidextrous BAD Rack-15 charging handle and a 9310 steel bolt paired with an 8620 black nitride bolt carrier group, which are individually head-spaced to ensure reliability. The 5.56 NATO chamber is compatible with both 5.56x45mm NATO and .223 Remington ammunition.
