AR-10® B SERIES QUAD-RAIL COMPLETE UPPER HALF ASSEMBLY



Item Number: U10A4CBFX

The AR-10A4 carbine complete upper assembly features a double lapped, chrome lined barrel.  The MIL-STD 1913 rail on the upper receiver and low profile gas block allow rapid and repeatable interchange of removable iron or scope sights. This carbine upper takes it a step further with free-float quadrail handguard specially fitted to Armalite’s low profile gas block. This allows maximum hand placement choice and accessory locations when a longer handguard is placed on a shorter gas system upper half.

Each Armalite complete upper assembly includes a forged upper receiver assembly, barrel assembly, bolt carrier group and charging handle assembly.  All complete upper assemblies are test fired as complete rifles before shipping.
