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
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.

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?
why does the buffer tube spacer rattle in the buttstock. is this normal?
mike r on Aug 8, 2018
BEST ANSWER: I do not believe that this is normal if the spacer is correctly installed. It does not rattle on my rifle. Everything is nice and tight.
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.
What is the difference in this kit and the 7788893B kit?
Salty G on May 29, 2018
BEST ANSWER: Absolutely nothing other than cosmetic imperfections. The "B" stands for "Blemish"

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....
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
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.

Over all love this rifle. All the reviews I have read is that a 1/7 twist will shoot a 55grn round. This upper shoots at 25 yards a 4 1/2 groups. I have not had a chance to shoot any 62 grn in it yet. But I would not hesitate to buy this upper again from Palmetto again.
Over all ok. It doesn't like 55grn.that much.

Better than expected, nice accurate shooter.
This weapons kit is well worth the investment. Adaptable for optics or carry handle/rear sight, this weapon meets the specs of the Viet Nam era, bringing nostalgia to the gun range. It is as good as advertised and performs consistently. BRAVO

Great base for an M16A4 MWS.
If you're looking for an easy way to put together an Army or USMC A4 clone build, this is a good choice. The Nitride barrel isn't completely accurate, but neither is the semi-auto receiver. Aero uses Nitrided barrels too, in any case. The A2 buttstock is excellent quality - they say milspec, and it is. Toss a carry handle on it and use as-is, or go all the way with a Knight's M5 and an ACOG.
Completed A4 MWS clone with M5 RAS and TA31RCO-A4.
Assembled as received.

All components came as advertised and assembled quickly. Just buy a lower and some sights. You are good to go!

Really fun kit
I picked this up as well as a carry handle for a fun Aforgery. It's a great smooth shooter and I was under 1 inch groups at 50 yards (with the irons).

The upper looked good and felt like quality. It is mated with an Anderson lower and cmmg parts kit. While shooting the first time, 90% of the shots resulted in short stroke no feeds. It ejected fine however and was accurate. I will clean, look it over and try it again before contacting customer service.

Ordered complete upper and lower build kit.
Added PSA carry handle and triangle handguards to complete my M16-A1 tribute. 100 rounds through with no issues shooting as accurately as I am.
