The Battle Arms Development Workhorse Forged 7075-T6 Stripped Upper Receiver (Battle Arms Development part no. WH556-UR-BLK) is the starting point for an AR15 upper build. Battle Arms Development forges it from 7075-T6 aluminum, finishes it in Type III hard coat anodize with a matte black look and cuts the top to match the Workhorse and RigidRail styling. It is stripped, so you supply the barrel, handguard, charging handle and the rest of the upper. It suits a builder putting together a custom carbine or pistol upper.
