Each 7.62x39 AR-15 upper is individually checked for proper headspace using Manson GO and NO-GO gauges before leaving Ballistic Barn.

Ready to Install:

The upper arrives fully assembled and is designed for use with compatible standard-dimension AR-15 lower receivers.

IMPORTANT AMMUNITION NOTICE

Steel case ammunition is generally acceptable for use in this upper. However, do not use lacquer-coated ammunition. The lacquer coating can heat up and accumulate in the chamber, which may contribute to extraction problems or stuck cartridge cases.

Important: This upper receiver assembly is not a firearm and can be shipped directly to you. No FFL is required.

Ballistic Barn AR-15 uppers are American made and assembled using quality AR-platform components. Each upper is individually inspected and headspace checked before shipment to help provide proper fit and dependable operation.

    Heck of deal on this upper plus I have tons of this ammo. Looks great in OD Green since it will be my new hunting rifle. The single feedramp is flawless, no feeding issues at all.
