Add To:

Barrel:  A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its required 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 rifle-length gas system.   The barrel  has a conventional .750" gas block diameter, is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected.  Barrels are finished off with a taper pinned, f-marked, front sight post, standard handguards, and an A2 flash hider.  Barrel is made for PSA by FN right here in South Carolina.

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.  Included is a PSA A2 Rifle Lower Build Kit.

PSA 20'' CHF Rifle Length 5.56 NATO 1:7 A2 Upper With BCG & Charging Handle - 516446156
PSA 20'' CHF Rifle Length 5.56 NATO 1:7 A2 Upper With BCG & Charging Handle - 516446156
BEST ANSWER: I would have to say yes. All of the 20" A3 style rifle kits have the exact same description for the upper and specifically say 'hard coat black anodized'. Some of the free float kits don't say 'black'.
Is this a government profile barrel
(heavy in front of the handguard and thinner under the handguard)?
Richard L on Dec 10, 2018
BEST ANSWER: Yes it is. This package is outstanding milspec +!
Does the stock have a trap door for cleaning kit?
Otlando C on Dec 28, 2018
BEST ANSWER: Yes it does.
Would this be a good starting platform for CMP Service Rifle competition? That is, practice, practice and practice some more, then rebarrel it with a match barrel, full float hand guards and upgraded A3 rear sight assembly. Thoughts?
Tom H on Dec 27, 2018
BEST ANSWER: Yes. This would be perfect for this. I built this rifle with that express intent.

Essentially a FNH Barreled Upper
This 20” FNH CHF barrel is absolutely amazing. My upper receiver happened to be a Brass Aluminum Forging Enterprises (BAFE), and featured the grey dry film lubricant inside. This barreled upper receiver assembly is the same quality as Colt, BCM, and FNH, at a much cheaper price point. BCG is HPT/MPI tested, and very high quality, likely made by Toolcraft. I have thousands of rounds through this setup without a single issue, I primarily shot ZQI M855, resulting in 2” groups at 100 yards with the barrel being non free floated. The LPK isn’t of the best quality but for the price of what you’re actually getting, it works fine, and the quality is focussed on the barrel, BCG, and upper receiver, which are the most important parts of the AR platform. My F marked FSB was aligned perfectly without any canting. I would definitely buy this again and recommend to anyone looking to own a 20” CHF quality made upper with FNH barrel.

Great Build
Everything went together perfectly. I've purchased quite a few parts and assemblies from Palmetto and I've been completely satisfied with their quality.

Palmetto is the very best overall kits on the market.
I have purchased many of these kits including this one and they all are far superior to any others that I know of tried over four other brands. The quality and price are a great way to build your AR-15 or AR-10. They are simply my go to people to buy from. The AR-10 has only one issue and that is extractor spring usually too stiff to work. I heard a lot of complaining in other reviews about this. It is a simple fix to use at 15 spring in your bolt and good to go. So if you have this problem fix it instead of thinking palmetto did not give you a great product. Fan for life

Great deal for someone wanting an A4 clone
I actually got this kit back in 2013/14 and have been consistently using this rifle as my "go to" gun out on a ranch in NorCal. Put it on a cmmg lower and it all mated up just fine. I get about 2" groups at 100yds using PMC XTac 62gr green tip and a Leopold CQ/T 3X scope which is right by me. I put an older DD 12" lite rail on and saw no change in accuracy but where this rifle really shines is out at 400yds on a hot barrel- I can put about 27 of 30rnds into an 18" silhouette target all day long. The CHF barrel just holds its accuracy out there even after it's gotten pretty warm and I don't see that kind of consistency out of many government profile barrels. I've dragged it through the dirt rain and wind thrown around in the back of a pickup and it never seems to jam. This is the rifle I'd take to war- I trust it more than any other I have.

Excellent Quality
I bought this kit on 9/1 and it arrived at my house 9/9. I mounted the upper on Spikes lower with an Anderson lower build kit. I was very disappointed in the Anderson lower build kit and it was one of the worst triggers I've ever seen (bad mistake). I should have stuck with Palmetto on the lower and build kit. The Spikes lower i feel didn't match up as well as my other Palmetto lower. Just stick with Palmetto for everything and you'll be good. The barrel has the FN roll mark on the 20" barrel and is awesome. I've been very happy with all my Palmetto parts.

I dare someone to show me a better product at a better price! PSA does it again!

Good for the money few things slipped through the cracks.
Compared to other 20" uppers I got this one for the CHF barrel. The uppers are good the only issue is one of them had an out of spec charging handle that will jam up any gun you put it in.

Packaging damaged the buffer and stock.
The kit was at my door in 3 days which is hard to beat. When I opened the kit all of the parts were in the same box with nothing keeping them from banging and rubbing together during shipment. The threads on the buffer tube were pretty mangled and I had to take a file to them to straighten them back out. The tube was also rubbed to bare metal in one place. Thankfully the tube was not dented or bent. The A2 stock was also lightly gouged in a few places on one side. I think this could have been avoided if the upper was better controlled and not allowed to slide around or if the other kit components were in another box inside the main shipping container. Everything else seemed in order so I assembled the kit without any more surprises. One trip to the range so far wihtout a problem. This kit is a good value and the A2 configuration is a joy to shoot.

Upper Slipped Through QC
Ordered this kit on 8/31/15 arrived at my door 9/2/15 super fast shipping. Everything in the kit looked great. Assembled this kit on a blemished PSA pictogram lower and everything went together with ease. Kit also has a decent trigger with it much smoother than a PSA build kit that I purchased in the past almost no grit at all for a standard trigger. Only issue is the upper came with the front sight post canted to the left. Called PSA and was sent a return shipping label. PSA received upper on 9/3/15 still waiting to hear back from PSA as of 9/7/15. Very disappointed to buy what I thought was one of their higher end CHF uppers to find the canted front sight. So far good customer service though. Will update review when my upper returns to me.

Excellent kit with some QC issues
I have been wanting to build an A4 clone for a while and this kit was exactly what I was looking for. Came very quickly and everything looked excellent. I didn't notice an issue until I took it out to the range to zero my detachable carry handle iron sights. I had to crank the sights almost all the way to the left to zero at 25 yards. It turns out the front sight is canted about 3 to 4 degrees to the left. I can make due with the irons but for a "PREMIUM RIFLE KIT" you would think they would QC a little better.
