Barrel: Barrel is made for Palmetto State Armory by FN Manufacturing using their proprietary blend of hammer forged chrome molly vanadium 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. Chambered in 300AAC Blackout, with a 1:8 twist, M4 barrel extension with extended feedramps, and a pistol length gas system. The barrel has an heavy profile, is mil-spec phosphate coated, and MP/HP tested. The upper is finished off with a .750" low profile gas block, Palmetto State Armory 9" Lightweight Free Float Rail, 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.
Each upper is assembled to order with care, and test fired.
