Add To:

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 rate, M4 barrel extension with extended feedramps, and a carbine length 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.

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: Bolt is made of Mil-spec shot-peened Carpenter 158 steel. Gas key is secured with grade 8 fasteners and staked per mil-spec. Bolt carrier is parkerized outside, and chrome lined inside.

Each upper is assembled to order with care, and test fired.

Great for SBRs
I used this as a suppressed SBR upper for a long while. It has worked great with no issues in this tough application.

Can you hear me now?
Love the upper! Great company to my 10 1/2" .300 blk pistol. Put 350 rounds of 5.56 NATO through it with no problems at all. Now I want the 7.5"....

I have been wanting to build a pistol with this upper for a while now but every time I checked it was out of stock so I signed up for the email alert for when it would come back in stock and I jumped on it when I got the email. I own one of their FN manufactured 16 inch chrome lined barrels and I love that barrel and wanted a mini me version. It turned out great and I could not be happier with it and its pretty accurate so far but I have not used a test to check how accurate.

Not perfect, but I would buy this again
The upper is very well put together. My only complaint is the BCG is listed as being chrome lined. The carrier I received is nitrided and appears to be of good quality. It just isn’t what I was expecting. I probably could have sent it back for an exchange, but I wanted to go shooting! It also doesn’t make sense to include a MPI bolt in a premium upper instead of the HPT/MPI that comes with PSA’s Premium Full Auto BCG. If it’s a premium upper all the parts should be top shelf. I would recommend that PSA pay a little more attention to detail.

Upper is awsome I always reccomend PSA for good quality for a great price. I really wish they would hire more people to get the orders out a little faster.
