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 5.56 NATO, with a 1:7 twist, M4 barrel extension with extended feed ramps, and a mid-length gas system. The barrel is a lightweight A2 profile, is Mil-spec phosphate coated, and MP/HP tested. The upper is finished off with a Geissele .750" diameter Super Gas Block drilled and pinned to barrel, A Geissele Super Modular MK14 M-Lok 13" Rail, and an A2 flash hider.

Geissele Rail: The MK14 is the latest entry to the Geissele line-up of Super Modular Rails. The new handguard design offers a smaller diameter and overall height to create a slimmer package. Included with the MK14 Super Modular Rail is an updated version of the proven Geissele Barrel Nut design, not only providing ease of installation but superior rigidity. The long surface contact of the 2.25” barrel nut interfaces with the receiver creating a platform that can be trusted to be straight and true the entire length of the free float rail. The MK14 is 3d precision machined using 6061-T6 Aluminum due to its strong, rigid and lightweight properties. 

Utilizing Magpul’s M-LOK technology in the 3, 6, and 9 o’clock positions allow the end user full customization and modularity of their rifle to securely mount lights, bipods, and other firearm accessories. The Geissele MK14 Super Modular rail is finished in a durable and long-lasting Type 3 Hardcoat Anodized

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. 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.

Can i have it ordered with a different muzzle device pinned and welded instead of the bird cage?
BOOSTED95 on Aug 24, 2019
with the "A2 Flash Hider, Pinned & Welded" does that bring the barrel length to 16"?
LAWRENCE F on Aug 22, 2019

When you pin and weld the flash hider, according to the ATF it is considered part of the barrel, and is 16". Some areas do have restrictions above Federal law, and do not allow this configuration. Please check you state and local laws.

I have been patiently waiting for this item for a couple of months. I am willing to wait a little longer , but I’m getting antsy. Any idea when it will be in stock?

Great deal. If you know your specs this is basically the USGI set up which starts at $1000. Love the quality. Buy this it's a no brainer.

Top tier upper assembly. Professional assembly.
Absolutely perfect rail/gas block installation and pin and weld job. Pure milspec 7075 upper with fine anodized finish and no flaws in machining. The FN barrel is perfect and roll marked. Light, fast, and accurate upper. Very pleased and glad Psa made this offering.

Best upper available from PSA
Well-balanced and lightweight. Good recoil impulse. Matches up well with a H buffer. I'm getting 2-3 MOA with 55gr and 62gr using a 1-8x optic, shooting of the roof of my car. I imagine some 75gr or 77gr OTM with a better rest and higher magnification would probably approach 1 MOA. Finish is good, and the rail is very usable. No issues with the weld, or QC.

Great in theory but upper receiver ruins it
It’s a nice upper if the actual upper receiver was mil-spec. The front pivot pin block of metal is way narrower than any of my other uppers causing there to be tons of slop (tried all combos of uppers on lowers and same issue always). There is no forge mark on the upper (there is in the picture) and it honestly feels like it’s made out of thin pot metal. Haven’t shot it yet and will be initiating an exchange this week.
