AR-10(T)™ A-Series Complete Upper Half Assembly


The AR-10(T)TM complete upper assembly features a triple-lapped stainless steel barrel floated within a rugged aluminum handguard.  The MIL-STD 1913 rail on the upper receiver and the gas block allow rapid and repeatable interchange of removable iron or scope sights.

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.

All Armalite complete upper half assemblies include a bolt carrier group and charging handle.

Armalite’s A-series uppers will only work with an Armalite A-series lower.

To know if you have an A-series rifle or lower look at your serial number.  The serial number will begin with an A, for example A000001
