Welcome to Palmetto State Armory!
Barrel: This barrel is made of 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 over a tapered mandrel, 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 300 AAC Blackout, with a 1/8 twist, M4 barrel extension, and a pistol-length gas system. The barrel is finished off with a PSA Slim Quad Rail (SQR) 9" Rail.
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.
Bolt Carrier Group: For AR15 and M16 rifles and carbines. Made by a mil-spec contractor, these feature a Carpenter 158 Bolt, and a full profile chrome lined carrier. Bolt is made of shot-peened, Mil-spec Carpenter 158® steel. Gas key is secured with grade 8 fasteners and staked. Bolt carrier is parkerized outside and chrome lined inside.
The upper and rail may have cosmetic blemishes that do not affect function. This may include, but is not limited to, forging marks under the finish, scratches, slight variation in the finish color coat.
