Product Description

The Battle Arms Development WORKHORSE upper receiver assembly is a durable, do-it-all AR-15 upper built around a 16-inch 5.56 NATO barrel and a mid-length gas system for balanced reliability and shootability. It features an A2-profile 4150 chrome-moly vanadium (CMV) barrel with a nitride finish and a fast 1:7 twist rate, paired with a free-float M-LOK handguard for mounting lights, grips, and other accessories. This configuration ships without a bolt carrier group (BCG) or charging handle, letting you select the components that best match your build.
