Is the front sight canted like all the other PSA rifles?
Raymond H on May 29, 2019
BEST ANSWER: Ive never recieved or seen a PSA upper with "canted fsb" PSA uses the same modern precision CNC machines and follow the same specifications to provide the consumer with a top quality rifle just as good other major manufacturers like Colt, BCM, FN ect..
what flip up iron rear sight will work on this?
J b on Aug 21, 2019
BEST ANSWER: Any modern rear sight should work. I used a Matech (because it is what I had) but MagPul, Trot, YHM etc will work fine.
Is this the same upper used in the Premium 20" Rifle Build Kit, SKU# 8818?

PSA 20
PSA 20" CHF Rifle Length 5.56 NATO 1:7 Premium Rifle Kit - 8818
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'.
I kept my bayonet from desert storm - will it fit on this upper properly?
Colonel on Apr 1, 2020
BEST ANSWER: It should fit no problem. As a retired First Sergeant, the last words you want to say are “Fix bayonets”. Having fired about 800 rounds threw this upper, it’s proven to be quite accurate. I did replace the BCG with a Fail Zero because they are easier to clean.
The 20” version isn’t supposed to have an F marked FSB, is it?
robert r on Aug 10, 2019
BEST ANSWER: Yes it does it is built on an m4 pic rail upper receiver for correct hight an F marked fsb will be used. However an A2 fsb with a taller sight post around.040 will work as well.
So this is a complete upper? Then I need a lower and what would be the best to go with this upper. This will be first assembly for me
Jason on May 20, 2019
BEST ANSWER: Yes complete upper with BCG and charging handle, any mil spec lower will work, that is up to you to figure what kind of lower you would like to put this wonderful upper on.
Is the BCG that comes with this upper HP & MPI?
David F. on Mar 30, 2020
BEST ANSWER: The BCG is mil-spec. It is the CHF barrel made FN that sets this upper assemble apart. I believe this would be a great value at ever a higher cost. I am amazed with this uppers pin-point accuracy. The addition of Palmetto’s EPT trigger assembly makes me a better open-sight shooter.
Is the BCG in the this kit the PSA premium one?
Sean C on Aug 22, 2019
BEST ANSWER: The description says, " Bolt carrier is parkerized outside, and chrome lined inside."
That sounds like the premium BCG to me. The regular BCG is not chromed lined.

Shiping to California? If so are they in stock
Bert S on Mar 28, 2020
Does this come with the premium bolt carrier group?

Great upper but issues
Great barrel but I do have some complaints. On a premium build which most of us are getting to build clones with why on a mostly phosphate upper do you put a nitride A2 flash hider and a nitride delta ring. Now I gotta tear the whole thing down and replace those. When I bought a nitride barel upper it had a phosphate A2 and delta ring. Totally makes no sense. And the dust cover has some strange finish I have never seen that looks like sparkles. The bolt carrier group I had hope would be a premium on a premium upper but it most certainly is not phosphate but not nitride? The charging handle also has a weird shinny finish. Guess the only parts I will save will be the barrel and gas tube. Should have bought the upper with no BCG and handle and saved money that could have been used to buy the replacement parts . First PSA product I have ever not been happy with.

Great 20” upper to complete my A3/A4 build.
The upper arrived four business days after I ordered it, so kudos on the fast shipping. Everything was packaged well and
discrete. Taking it out to the range for the first time and putting 150 rounds through it everything worked great and it shot very accurate; I was able to 3” groups at 100 yards using iron sights from this CHF barrel. If I had to say only one thing negative, it would be I couldn’t get a clear answer in whether of not this upper package comes with PSA’s premium BCG. I was totally willing to pay a slight extra shipping charge in order to get the extra quality from their premium BCG, non the less the BCG in this package is staked well and functions as expected. I would recommend this if you’re in the market for a 20”AR.

Nope, Never Again
PSA sent a request for a review, so here it is.:

My sample is flat rate TERRIBLE! I tried various ammo from 55gr ball to 77gr match from known vendors. Laid over my range bag using a 10x scope, the best I could get was about 4.5" at 100yrds.

The same day I zero'd a PRO on a 12" LMT gun and shot a cloverleaf at 50yrds. To appease those who scream 'shooter error', I am a full time law enforcement firearms instructor with NRA, state and federal level teaching credentials.

Fit and finish were fine, zero stoppages for the time I spent shooting it. Now it is tossed in the corner as a project gun until I can buy a barrel from a known vendor.

Response from Palmetto State Armory
We do apologize for that. We warranty our barrel's 16 inches and over for maximum of 1.5 MOA. If you feel like you are not receiving this level of accuracy, utilizing a rest, match ammo, and proper shooting technique, please contact Customer Service so we can assist you.

Good for sporting, barrel is quality and should last the average joe many lifetimes. The bolt carrier and charging handle is not up to mil spec. I replaced both. The charging handle bent like play-doh and the replacement they sent was still garbage quality. Skip this and buy the empty upper with just the barrel installed and separately purchase the PSA Premium parts to finish it.
