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.

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.

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

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
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
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.
Is this full auto if yes do you have to get it registered?
Trista H on Dec 26, 2019
BEST ANSWER: Seriously, you can't just order up a machine gun parts kit, let alone a rifle.
When will this beauty be back?????
Edatc on Apr 24, 2020
Is there anything other than a stripped lower you will need to finish this build?
Shawn M on Apr 20, 2020
BEST ANSWER: I purchased a mil spec carry handle for one, get one from PSA right now if you want to go that route. Much better than the other brand for 30 bucks IMO. This is their premium kit, it will last a lifetime.
Do I need a special a2 lower for this kit or will all ar15 lowers fit?
Ryden on May 15, 2020
BEST ANSWER: Yes it will fit your basic AR15 lower. I purchased one from PSA because I'm real particular about my upper and lower being manufactured by the same company but you can use any lower you prefer
What is missing to make this the whole gun?
Kent E on Feb 2, 2020
BEST ANSWER: A lower receiver and a rear sight. For the rear sight you could do a carry handle for a "traditional" look, a flip up rear sight or a static sight, all will get the job done.

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: The gas block on my 20" CHF rifle (sku 8818) is pinned.
why is the buttstock light grey and not black like rest of rifle?
greg b on Nov 6, 2019
BEST ANSWER: HI Greg; My CHF stock is black and only turns grey when orks are nearby. Really though the color difference is very slight on mine and can be adjusted with a quick rub down of 'Son of a Gun' or 'Armor All'. I hardly ever noticed it before I saw your question.
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......
What's the actual accuracy you've been able to achieve with these rifles?
Preston G on Oct 22, 2019
BEST ANSWER: I certainly can’t speak for everyone, but with a 4x ACOG and XM193 ammo, I consistently put rounds into 1-2 inch group at 100m, shooting unsupported prone. It is worth noting that my upper has a Knights Armament RAS M5 handguard, so it is not free-floating the barrel. Keep in mind, your results may vary.
How long is the front grip?
Jake S on Aug 31, 2019
BEST ANSWER: The handguard is rifle length which is 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.

First Build, Good Value, Very Happy!!!!
Kit has everything you need to turn your lower into an m16 clone AR 15. The parts are well made and the design very simple. The kit has all parts in separate bags which was a huge help to a first time builder like me. I was able to complete the build in less than an hour after watching the TFB AR build video from youtube. I had a question about this system and PSA responded back in a good time frame. The kit doesn't require a castle nut tool either. It doesn't come with any type of optics or rear site but ordered me a nice scope which I plan on adding in a home made thermal function on the scope rail , but a very nicely made rail on the 20' upper. I put 100 rounds through it yesterday with 0 malfunctions. Thanks for what you do PSA, you definitely have my business!

Very nice upper bought a PSA lower everything went together as it should cleaned and oiled it before I took it to the range put about 250rds through it 0 issues with anything

Good Affordable Option for practicing Iron Sight
It is not as nice as the FN counterpart but it is about half the price. PSA also has the full upper, stripped upper, full rifle and rifle kit. A lot of different options built based on the FN barrel. If you are looking for a platform to shoot using iron sight, this is a very good option. Or if you want a M16 like rifle with ACOG, this is the deal. If you are looking for something to put a red dot or scopes on, shop for something with a free float hand guard. There are plenty of those modern ones on the market. I did some modification to mine: a narrower front sight post, MBT trigger, and lead insert in the stock. I really enjoy shooting this rifle using iron sight.

BUY IT! well worth the money.. I'll be using this as a trainer it's big and heavy, build muscle memory..
Fit and finish was top tier, I've put together a few different brand names thought the years and this kit #8818 went together perfectly.. If i had to be critical it would be the handguard which seems to be unique to Palmetto, I'll be replacing them traditional A2 Style.

Had some issue in the first 100 rounds using steel cased ammunition. Had to mortar a few rounds out and had short stroking issues. Then again I was using cheap golden tiger ammunition. After that break in period the rifle ran flawlessly with everything I put in it.

Only two stars
This is my second purchase of a premium upper in three months and my first upper the flash hider was incorrectly clocked. Its a minor issue so I let it go without a complaint to customer service. Set my sights on purchasing another upper, a 20 inch premium, and weighed my options of purchasing from BCM or PSA. Decided to give PSA another try even after my first barrel purchased had an incorrect flash hider clocking. Received my 20" premium upper and discovered front sight had left over flashing from casting mold which should have been removed after processing. Dust cover latch when closed was weak and would pop open with slightest bump to upper. And finally a shiney flash hider and delta ring, just doesn't look correct with the rest of the flat phosphate look of the rifle. Contacted customer service and thankfully they worked with me to send a replacement. Haven't received it yet so fingers are crossed that there are no issues. By the way, clocking on 20" upper was dead on perfect and hopefully my replacement will be the same - as well as matching delta ring and flash hider texture on my premium upper.
