I have an UNFIRED PSA 10.5" CHF Pistol Upper in 5.56/.223, it is in mint condition! I am selling because I decided I want to make my pistol a different caliber. I have upgraded the upper with a Magpul MOE carbine hand guard, and a Troy Claymore Linear Compensator.

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 enanced durability. Chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension with extended feedramps, and a carbine gas system. The barrel has an A2 style profile, is mil-spec phosphate coated, and MP/HP tested. The upper is finished off with an F-marked front sight post with sling swivel, and an A2 flash hider. 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.
The Troy BUIS are not included or for sale.
