This barrel is made for Palmetto State Armory by FN, 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 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a carbine gas system. Barrel has an A2 style profile, is Mil-spec phosphate coated, and is Mp and HP tested. 

Please check the barrel closely for any irregularities. It is the builder's responsibility to check headspace before assembling.

In the unlikely event you have an issue with a barrel, STOP AND DO NOT ASSEMBLE. Contact Customer Service.  Barrel is non-returnable once installed.
