Shawn C on Dec 11, 2018

When will this be available?
James on Oct 30, 2018
Is PSA ever going to make this with the permanent carry handle and rear sight? Trying to build the Iraq lower so it is as close to what I carried over there as possible.
Pete on Jan 23, 2019
BEST ANSWER: I have seen the A2 upper on Brownells site
When are these going to be available again?
Brian on Nov 19, 2018
Is there any difference between this and the freedom variant other than the barrel?
William G on Apr 17, 2019
BEST ANSWER: Does the freedom have a canted front sight? The 20" CHF, Machine gun steel, hype, hype, hype, comes with canted front sight, and no response from PSA's customer dis-service. Thank you for no-service PSA.
When will these be in stock again?

To the fellow owners of this kit, Did your upper have T markings on it? None of the PSA uppers that I've bought had T marks on them even though they are advertised as having them.
Dave P on Apr 17, 2019
BEST ANSWER: Mine does not have T markings.
CHF indicates what? I didn’t see CHF explained. Please educate me. Thanks.
john d on Jul 23, 2019
BEST ANSWER: Enter an answer to CHF Barrels are built to be of the highest quality, extremely durable and long service life. Cold Hammer Forging of barrels has been known to produce accurate and longest lasting rifle barrels obtainable. The process also creates a defect free bore and the most consistent chamber possible. question.
Does this upper have round or rectangular handguard retention in front?
Jesse G on Jun 24, 2019
BEST ANSWER: It has a triangular handguard cap in the front.
Is this able to accept a bipod?
Max on Apr 17, 2019
BEST ANSWER: This is modeled after A2 style rifle and has no provisions for accessories
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: This is a very special barrel with a very special front sight. They drill and pin the front sight tower on crooked or leaning to the left. You'll use up all of you windage and you might be zeroed at 25 yards. At 50 yards, you'll need to hold off on the target and make hook shots!
With this Hopper is it possible to put 1 round handguard on the left side in a triangle handguard on the right side to compensate for the crooked front sight. Myfrontsight is only one inch off to the left crooked just didn't know if this would help??
Mike D on Jun 16, 2019
BEST ANSWER: send it back
Is the trigger polished?
Death b on Aug 23, 2019
BEST ANSWER: The trigger is not polished; it is a basic mil-spec in the way it suppose to.
I never built or used an AR before, what else do I need to complete a fully functional rifle ?
Victor M on Sep 20, 2019
BEST ANSWER: The upper portion of the rifle is built. You need a lower receiver only, the serialized part, usually 40.00 to 50.00 dollars at PSA. This kit ships directly to your house, the serial numbered lower must ship to an FFL. They are very easy to put together.
Is the Gas Block pinned on, or is it held on by a set screw?
Benjamin W on Aug 14, 2019
BEST ANSWER: Mine was in the bottom of the box when it arrived. PSA can't correctly assemble a rifle.
Is the BCG the PSA premium BCG in this kit?
Sean C on Aug 14, 2019
BEST ANSWER: I don't have another PSA premium BCG to compare mine to but it better be. Everything about the premium kit I received was exactly what it said except it was missing the T marks on the upper reciever. Customer service gave me some options and took care of it how I wanted to. The rifle is such a great shooter.
Does the upper really have the markings. The last 2 chf uppers I bought were blank and they didn’t even have forging stamps??????
Chris W on Jul 1, 2019
BEST ANSWER: The one I purchased did not. Just the FN markings on the barrel are there. However I purchased a nitride version of the same rifle and that one actually came with the square forging mark on the upper receiver. Go figure......
How long is the front grip?
Jake S on Aug 31, 2019
BEST ANSWER: The handguard is rifle length which is 12 inches
Are the barrels still canted? Has PSA figured it out? Companies have been making this product for 55 years. Did PSA get a clue?
Raymond H on Aug 1, 2019
BEST ANSWER: I received my kit in January 2019, and my front sight base is straight. I use a backup rear sight, but it took minimal windage adjustment to zero.
Does this include an M16-style carrying handle/rear sight?
Cara M on Apr 1, 2019
BEST ANSWER: The front sight is canted, and you won't be able to use iron sights anyway.
Is this the same upper used in the Premium 20" Rifle Build Kit, SKU# 8818?

PSA 20" CHF Rifle Length 5.56 NATO 1:7 Premium Rifle Kit - 8818
PSA 20
PSA 20" CHF 1:7 A2 Rifle Length 5.56 NATO Premium AR-15 Upper Assembly - with BCG/CH
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'.
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: Enter an answer to this question.I would have to say NO. The hand guard is not free floated. If you sling up tight like you will need to, to shoot your rapids, you will experience both elavation and windage shifts. And that shift will not be consistent. Get yourself an upper with a float tube that is set up specifically for service rifle competition. This advice is from a Distinguished Rifleman and P100 (rifle) Shooter.

Also, forgo irons now that optics are legal. Get a good two stage trigger that will lif5 4.5 lbs. LaRue make a good one at a very reasonable price.
Anyone know if they have resolved the front sight wanted issue?
Nathan W on Oct 9, 2019
BEST ANSWER: mine was straight
What is the length of pull (LOP)? wonder a youth can use it. Thanks.
libarrel on May 27, 2019
BEST ANSWER: Look up the M16A2 specs. They are on line.
Can I replace the round hand guards with original A1 triangle hand guards? If so, is it easy as popping the round ones off and installing the triangle ones? How should one install triangle hand guards in detail?
PAUL J M on May 24, 2019
BEST ANSWER: i haven't changed them myself but you should be able to replace them with any drop on rifle length handguard
One question
For lower receiver Buttplate (with trap door), is it metal? or plastic?
Jonny L on May 1, 2019
BEST ANSWER: Plastic. Has a plastic-hollow sound, kind of a twang sound if you shoot with it. Try to avoid dropping it.
What’s the length of the Handguard?
Andrew Q on Feb 18, 2019
BEST ANSWER: 12 Inches
What lower is recommended to be used with this kit?
daniel852 on Feb 8, 2019
BEST ANSWER: Any stripped AR-15 lower for NATO 5.56mm or .223rem you have should work with this kit.
Does the stock have a trap door for cleaning kit?
Otlando C on Dec 28, 2018
BEST ANSWER: Yes it does.

FN CHF stuff
Once again another awesome, flawless FN marked CHF upper with a kit. It’s perfect and as described.

Another good looking rifle at an affordable price.
This is my 3rd premium CHF build kit from PSA and like the others it gives you a lot for your money as compared to other options out there including sourcing the same spec parts yourself.

I will say that the 1st upper they sent me was not right. The upper itself was out of spec to the point the charging handle was biding when cycling the bolt, and the front take down pin was impossible to push in and out without using a plastic hammer and punch. I contacted PSA customer service and withing 24hrs was advised to return the upper. I had a new one back in my hands 72 hours later and it's been 100%.

This is my 6th PSA branded firearm including an AKV-9 and the 1st I had any type of issues with and had to send back. Sadly I have not had a lot of one and one time with this set up yet but so far so good.

I would defiantly recommend and buy again.

Good rifle but front sight tower off center
I purchased this kit and used a palmetto state stripped lower receiver to put together a rack grade rifle to use to practice combat matches for the national guard. I’ve only shot it once. I used it for the modern military match at camp perry with a mil spec detachable carrying handle. The rifle easily held the 10 ring at 200 yards. My only complaint is the front sight tower is off center because I had to crank my rear sight pretty far to the left.

It's great, buy it.
It's a great rifle, very accurate & light.
I used a geissele SSA-e, bcm qrf, & aero a4 lower, with a carry handle. Might be one of my favorite rifles.

Great upper that should outlast you....
Great solid upper(Mine WAS T marked) the barrel speaks for itself .I wanted a 1st Gulf warish 20 inch without alot of junk hanging off of it for a change of pace and this upper was perfect......I matched it with a PSA lower which did give me a bit of a gap between receivers but nothing im going to cry about as it's solid with no wiggle and you cant tell unless your looking for it with a hairy eye...
My 20 inch I named Swarzkopf......

Good deal
Not a bad deal my front sight post was straight. I was surprised that I was able to get about 2MOA or better at times with open sights. The fit and finish was good my only problem is the lower parts kit I thought the trigger group would have been the premium from palmetto but other than that I would buy again

Great kit
I've been trying to find one of these kits for a while, but on the rare occasion that I do find one it is usually $1,200-$1,400. When I saw this kit for $500, I bought it on impulse. It works great and shoots just fine.

Great rifle
Got the rifle kit as a project for my son and I to build together. Everything went together fine except for the rear take down lug on the upper had to be drilled out for the pin to function properly. Otherwise, it was a strait forward AR build and shoots great.
