Details:

Short-barreled rifles (SBR) or AR Pistols are excellent self-defense and range weapons. The Battle Arms Development 5.56 WORKHORSE Upper is made with a short 10.5-inch barrel and is a strong option for an SBR or AR pistol.

Built to Last

This upper assembly includes a barrel, modern M-LOK handguard, gas system, and receiver. The barrel is 10.5 inches long and is made from 4150 Chrome Moly Vanadium which is super strong, accurate, heat resistant, and corrosion-resistant as well. The barrel has a 1/2"-28 thread pitch and comes with a standard A2 style flash hider.

Ready for Accessories

This Upper Assembly comes with the Battle Arms Development 9.5-Inch WORKHORSE handguard. This low-profile rail has M-LOK slots on the sides and the bottom, with a full-length Picatinny rail on the top for mounting modern accessories and optics. The low-profile gas block fits nicely inside the handguard, and it uses a carbine-length gas tube, which is ideal for a 10.5-inch barrel.

Lastly, the Mil-Spec upper receiver itself is precision made with 7075-T6 Aluminum. It has a forward assist and port door, all of which have a uniform black finish. The receiver features M4 feed ramps for improved reliability as well.
