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.

BEST ANSWER: 1000 rounds of 223 ammo and the psa 20 inch a2 upper
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?
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?

BEST ANSWER: Absolutely nothing other than cosmetic imperfections. The "B" stands for "Blemish"

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....
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.

Looks Nice Except the Stock
I really like this gun - I haven't shot it since putting it together, but I'm excited to do so. The one complaint that I have is the stock. The color doesn't match the rest of the rifle, and the material almost feels like felt. It's not polymer like the rest of the furniture. Because the material is fabric-like, it absorbs the lubrication & oil from the reciprocating bolt. The oil that has seeped out of the receiver has tainted the stock - you can see an ugly line where the oil has soaked into the stock material.

I dig it
Always wanted a 20-inch ar similar to the old ones. This kit makes it close and serves my purpose. I am happy with it. Shoots good.

High quality, and I’m recommending Palmetto to anyone that asks about build kits.
Easy kit to put together, all the pieces came well organized in individual bags, and well lubricated. I bought a lower locally and put it all together in under an hour and a half, had to beat the wife getting home from work. So far, I’ve put about 600 rounds through the rifle and no hiccups. Zeroed the red dot at 50 meters and can tag steel at 200 meters all day. The A2 rifles are extremely underrated these days, and shouldn’t be, due to barely any felt recoil from the rifle length gas system. Love the rifle, high quality parts, overall great bang for your buck.

Balls on at 300 yards out of the box!!!
Added the A2 upper handle and zeroed at 25 yards, this sucker was driving nails at 300 yards with groups the size of my hand. But the 20" is hard to find in stock.

After having my bbl. replaced at NO CHARGE by PSA. with a new one. (Front post slightly off) I HIT THE DOT size of a needle eye at 25 yds.of a U.S.ARMY 25m. M16A2 zeroing target on the third try after making my windage adjustments, YES OPEN SIGHTS. I highly recommend PSA BBLs.
