Battle Arms Development Workhorse 16" 5.56 Upper

Battle Arms Development Workhorse Upper Receiver

The Workhorse represents a thoughtful approach to the modern sporting rifle. Built around a forged 7075-T6 aircraft-grade aluminum receiver, this complete upper delivers the kind of reliability and accuracy that separates quality builds from the rest.

What You Get

This is a complete upper receiver assembly—everything you need except the lower receiver. Simply install it on your AR-15 lower and you're ready to shoot. The individual head-spacing of the bolt ensures proper function and easy maintenance.

The Workhorse Philosophy

Battle Arms Development built this upper for shooters who value reliability without compromise. The free-float handguard isolates the barrel from external pressure, promoting consistent accuracy. The full-length Picatinny rail gives you mounting flexibility for optics and accessories. Whether you're training, competing, or simply enjoying time at the range, the Workhorse delivers.
