This Hardened Arms LLC 7.62x39 upper comes with a 15" Hardened Arms made tactical free float quad rail, that is designed to fit the upper receiver flawlessly. Held in place with 8 screws for a tight lock up, the fit and finish are among the best in the industry. The 7.62 x 39 upper for the AR15 platform is one of the best kept secrets of the  AR15 world. Superior knock down power, a .30 call bullet heavy enough to hunt with and enough velocity to maintain a surprisingly efficient trajectory, while using very affordable and plentiful ammo. Our 7.62 x 39 uppers run great with steel cased FMJ ammo on the practice range or get in some serious hunting using brass cased FMJ and watch as your upper delivers superior accuracy and results.

Hardened Arms LLC 7.62x39 uppers are reliable and accurate. We head space, inspect and test fire each upper prior to them leaving our machine shop. They are built in-house using stringent specs, top quality parts and procedures to make sure you get maximum reliability and performance. We use 7.62x39 bolts made in-house to meet the proper specifications for the caliber, unlike some manufacturers we don't mill out 5.56 bolts as this leads to improper headspacing. We offer an optional BCG which comes with an enhanced firing pin, 7.62x39 magazine which feeds the round at the proper angle and a quality charging handle. We highly recommend this package for your 7.62x39 upper for the best dependability.
