The Battle Arms Development WorkHorse 16" 5.56 NATO Complete Upper Receiver drops onto your AR-15 lower and comes with the bolt carrier group and charging handle already included.
It is built around the forged WorkHorse 7075-T6 aluminum upper receiver. A free-float handguard has M-LOK attachment points at the 3, 6 and 9 o'clock positions, and a full-length Picatinny rail runs along the top with Battle Arms' signature notch cut matching the receiver. The 16" barrel is 4150 chrome-moly steel with a black nitride finish for durability and accuracy. Each barrel is individually headspaced with a matching 9310 steel bolt, riding in an 8620 steel black nitride carrier that is easy to clean. A Bad Rack-15 ambidextrous charging handle completes the upper.
Features:
Fit check: fits mil-spec AR-15 lower receivers. Confirm the takedown and pivot pins line up and the upper closes without binding.
Clean and lube the BCG before the first range trip, then function-check the rifle and run a short break-in with quality ammunition.
