Barrel:  A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as “Machine Gun Steel” by virtue of its use in FN’s M249 and M240 weapons.   The hammer forging process work hardens the steel, making it more durable.  In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability. 16″ length, 300 AAC chamber with a 1:8 twist, MPI & HPT, chrome-lined, carbine-length gas port, and M4 feedramps. Barrels are finished off with a taper pinned, f-marked, front sight post, standard handguards, and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. Featuring machined T marks, and a mil-spec finish. These uppers are made for us right here in the USA by a mil-spec manufacturer, and are marked with the Palmetto State Armory logo on the left side, up front, just below the rail.

Bolt: Bolt is made of Mil-spec Carpenter 158 steel, Shot peened, and MPI. Gas key is secured with grade 8 fasteners and staked per mil-spec. Bolt carrier is parkerized outside, chrome lined inside, and laser engraved with the Palmetto State Armory logo

Each upper is assembled to order with care, and test fired.
