How do the barrel quality and accuracy compare to this same setup with the FN CHF Chrome lined barrel? Should I wait for that to come back?
Woody S on Jul 25, 2018
BEST ANSWER: Hammer forged is stronger but not as accurate.
Who is the manufacturer of the A2 fixed stock?
elwood F on May 27, 2018
BEST ANSWER: Good question. Why do you want to know?

will the wife be mad if I buy this?
nite f on Jan 4, 2019
BEST ANSWER: Just remind her it’s only the first gun you bought this year.
Can I change out the handguard to the A1 triangular handguards?
Art E on Apr 23, 2018
BEST ANSWER: Yes you can. Back in the day many moons ago the Army didn’t have enough a2s in inventory so training units were issued m16a1s with a2 furniture installed to get basic trainees use to the feel of the weapon they would eventually be issued. My point is the triangular forearm retaining cap will work with both types.
why does the buffer tube spacer rattle in the buttstock. is this normal?
mike r on Aug 8, 2018
BEST ANSWER: As long as it's installed correctly the rattle is no function issue. If you want to eliminate rattle put a dab of GOOP on hex end of buffer tube and re-install. After curing the rattle will be gone. GOOP is not permanent and can be removed fairly easy.
Does this kit come with front sight? Kit778893
Mark G on Dec 4, 2018
BEST ANSWER: Yes. Iron sight on the front. This is a great AR. I’ve run good brass and super dirty steel cased ammo with no issues, it feeds everything like a champ. Solid rifle.
If I buy this kit, will the only other things I need be a PSA AR-15 lower and a magazine? And ammo?
Thomas A on May 11, 2018
BEST ANSWER: Any mil-spec stripped lower should work. It does not have a rear iron sight so you'll need one of those or an optic to fire accurately, but functionally you only need this kit and a lower.
Is the A2 stock mil-spec (metal door latch)?
Steve S on Dec 12, 2018
BEST ANSWER: CORRECTION, unlike the original Colt, these are a very well made polymer that most manufacturers seem to be using. My Colt HBAR Sporter built in '92 has the same type.
What is the total length of the rifle when assembled? I'm buying a bag before buying the kit.
S T on Oct 26, 2018
BEST ANSWER: The overall length of the assembled rifle is approximately 40 inches.
what lower receivers work well on this build does any one has like part number or list of options ?
Adan P on Apr 28, 2018
BEST ANSWER: Any mil spec lower will work well I presonally use aero precision lowers on my builds but psa makes a great lower for not alot of money
Kit 7788893 does it have front sight included?
Mark G on Dec 4, 2018
BEST ANSWER: The front sight is connected to the end of the handguards/barrel towards the front of the muzzle (you can see it clearly in the picture. There is no rear sight included, which is what I assume you were asking about.
Is this the triangle end cap or round end cap?
Yongkun D on Sep 27, 2018
BEST ANSWER: I've bought too many uppers from PSA and every end cap has been triangular. For those who say theirs is round, I'd want proof. But ANYWAY, most good quality handgurards will work with round or triangular end caps.
Can you install a suppressor on it?
Austin M on Nov 3, 2018
BEST ANSWER: It has a threaded barrel so it shouldn't be a problem, though you may want to add an adjustable gas block
Is this a pencil barrel or the heavier barrel?
Darla2rocks on Feb 1, 2019
BEST ANSWER: It is a heavier barrel. Similar to their other barrels that are not M4 profiled.
Anyone know if this the same cold hammer forged barrel as item #516444711?
Thomas J on Feb 8, 2019
BEST ANSWER: I do not. However. I bought this kit. I shoot Precision Rifle with it. Great accuracy. Enter
Is this a hammer forged barrel? FN or made in house at PSA? Thanks in advance.
Thomas J on Feb 8, 2019
BEST ANSWER: fn or made in house
Does it come with a carry handle?
Georgia_01 on Dec 28, 2018
BEST ANSWER: NO
Looking to buy this kit. Does anyone or can someone from PSA tell me who makes the barrel please? Want to know for quality and accuracy, Thank you.
Yann B on Dec 3, 2018
BEST ANSWER: It was gritty but took less than 2 mags to smooth out. Accuracy was average with standard ball ammo from 55 grn to 62 grn.
“Nitride finished barrel.” Does this mean the QPQ process? If it is, that’s great.
James S on Nov 27, 2018
BEST ANSWER: Yes, same process different name
What is the difference in this kit and the 7788893B kit?

Where can I buy triangular A1 style handguard?
Bill M on Apr 30, 2018
BEST ANSWER: Several places. Try The Google...NOTE: The Q&A here at PSA specifically says, "Do not include HTML, links, references to other stores, pricing or contact info," so... I can't tell you....
Is the barrel under the handguards reduced in diameter or the same diameter out to the barrel past the front sight?
Gregory B on Jul 13, 2018
BEST ANSWER: It’s smaller under the hand guards like the original A2 profile. It is not an hbar.

Disappointed ☹️
My first AR-15 from PSA was a mid length 16" nitride upper. Without any dings or scratches.

My second is this rifle kit. The upper had a 'dent' near the pinned gas block, marring near the gas port (I suspect from a set screw that was used to drill the gas port), scratches deep enough to remove anodizing from the rails on top of the receiver, and scratches on the charging handle. Aluminum black finishing covered everything but the scratches on the charging handle.

I thought this rifle kit was used or assembled by a drunk employee. Are at the least a blemed upper receiver.

One of my best AR's yet!
This rifle hasn't had any performance issues yet. It shoots accurately, and it even looks nice. The finish is nicer than my Colt. This is the best value AR that I know of.

Good Kit
I purchased my kit in December 2017. The upper receiver arrived completely assembled. All the other parts went into an Anderson lower without difficulty. The assembled rifle came out well and functions as it should. Using good ammunition with good bullets it will shoot 4” groups at 200 yards (2 MOA).

I am pleased with my rifle and would recommend it to anyone wanting a AR15 A2 or A4 style rifle.

10 out of 10
This 20 inch rifle kit is very nice. I took it out to the range and it was very accurate. I am very happy with Palmetto and their product that they put out. I would recommend a 20 inch kit to anyone. You cannot go wrong with Palmetto’s prices! Good chance I’ll be a customer for life.

If you are looking for an old school A2 build, on a budget, this is it. Priced right and everything feels and operates perfectly. Takes me back to boot camp and the FMF.
