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.

Do these barrels have fn makings?
Justin S on Jan 3, 2019
BEST ANSWER: Yes under the forward handguard on the top of the barrell. A little advice if you are going to take the handgurd off and check save yourself a lot of headache and get the handguard removel tool.
What gas port size are on these uppers?
Michael D on Nov 19, 2019
BEST ANSWER: I’ve not seen it published, but I recall a representative of PSA stating that it was “somewhere between .075 and .080.” Is it over gassed? Perhaps slightly, but of course they’re mass producing a barrel for people shooting everything from Black Hills 77gr OTM to Barnaul steel...and everyone is going to expect it to cycle.
Aren't all these CHF barrels and chambers chrome-lined, FN barrels, as stated in description? Was there a period of time in which they weren't chrome lined, or more likely did reviewer below leave a review for wrong upper?
Mike F on Dec 9, 2019
BEST ANSWER: Every upper with a CHF marked barrel are FN Chrome lined and have always been since I have started following PSA since last year. I think its likely the reviewer (who I could not see on my end) was probably commenting on one of their Classic Line uppers, which visually look very similar in the pictures.

But just to reiterate. If its CHF, its FN Chrome lined. Always.
When do you expect to have them in stock again?
Ludovico B on Mar 16, 2019
Do you have to file paperwork just to purchase the upper?
Gary M on Nov 21, 2019
BEST ANSWER: No, you do not need to file any paperwork in order to purchase this, but you should be aware of the legal ramifications of when you install this onto a lower receiver.
Will the Knights Armament carbine length RAS M4 rail fit this upper?
Derrick H on Jul 30, 2019
BEST ANSWER: Yes I had one on mine for a bit
Is the BCG the premium line or standard Mil-Spec?
Happy on May 3, 2019
BEST ANSWER: Mil-Spec is what came with mine. Works just fine ! :)
any PSA logos anywhere on the upper or bcg?
john l on Apr 16, 2019
BEST ANSWER: There is a small PSA logo on the upper, but not on the BCG.
Are the A2 front sights pinned on these?
Daprang on Jan 27, 2020
BEST ANSWER: The pins on mine were so tight that they could not be driven out with a hammwr and punch. I had to dremel cut the sights off.
Does the upper come with circle or triangle end cap?
Kevin B on Dec 10, 2019
BEST ANSWER: Mine cam with a circle endcap. I swapped the handguard out for a Troy drop-in quad rail.
Do these premium uppers come with the premium bolt and BCG or the standard?
Cjescue87 on Dec 30, 2019
BEST ANSWER: Just looked at the couple I have they have the PSA logo but look like standard milspec issue. Phosphate with MPT marks and well staked. Good, reliable, full auto profile BCG. Buy one of these they are accurate to 200yds with nothing more than an A2 carry handle. Under the handguard is the FN logo it's the Real McCoy. Very good deal at this price.
Does PSA make this style upper in 9mm similar to the Colt CAR with gas deflector?
Robert L on Jan 26, 2020
BEST ANSWER: Not that I am aware of. I have never seen one advertised in the PSA website.
Are these barrels dimpled for gas blocks?
Faris A on Dec 25, 2019
BEST ANSWER: No they are not.

Fantastic upper
Got my 10.5” CHF upper as my Christmas present and have been very pleased. Put it on one of my SBR lowers and it handles and shoots perfectly. The FSB was aligned right and very happy with construction. Was looking to by another with the Geissele 9.5” rail for my birthday but it is OSS.

My new favorite AR.
I love this upper! I've owned several ARs and I bought this to put on top of my lower build which is also from PSA and now this is my favorite. Ran flawless, accurate tight groups at 25 yards. I can't say enough good things about this firearm and PSA.

Fit and finish is excellent. It goes bang like it should, not much else to be said. Best value for a hard use short 10.5” hands down. Perfect base for a Mk 18 build.

Mine has a bad BCG..
Put upper on a Ruger receiver and realized the machined groove on the bottom of the bolt carrier was out of spec and hitting my buffer retainer pin when cycled. I thought it was possible the Ruger was defective so I tried the upper on a DPMS, Bushmaster, Aero, and Colt lower. The BCG hit all the retainers and I was able to safely determine the BCG was out of spec.

Add a drop in hand guard and Bob’s your uncle.
FN stamped CHF, BCG which appears to be of quality, nice and straight assembly: very impressive value. Don’t believe everything you read on the internet, good or bad...and with a relatively healthy AR collection represented with known quality brands (BCM, BA and LaRue) this upper fits nicely right in the middle of them in my safe. I’d say buy with confidence.
