Do you not have to have a special license if it’s automatic?
Thomas H on Sep 20, 2018
BEST ANSWER: The Bolt Carrier Group profile is “automatic” style; the rifle is semi-auto.
Do I still need to have this mailed to a FFL here in California?
miguel v on Oct 4, 2018
BEST ANSWER: The words "full auto" in the BCG description describe only the profile of the carrier, not its functionality. The BCG is not what makes a rifle fully or semi-automatic anyway; that is the fire control group (trigger, hammer, & selector switch). I see absolutely no reason why this kit would be illegal in Commiefornia simply because the BCG has a "full-auto" profile.
With this kit and more the stripped receiver does need anything more for fire the gun?
F F on Oct 28, 2018
BEST ANSWER: Yes, ammunition would help out alot. You will want magazines and a person to pull the trigger. And yes a receiver.
What is needed to complete the the rifile?
John T on Sep 21, 2018
BEST ANSWER: Just a stripped AR15 lower.
Does the furniture in come in seperate factory packaging?
Barrett R on Sep 21, 2018
BEST ANSWER: Not factory packaging. What are you asking?
There are 3 small spring, 2 silver and 1 black. The black is about 1/16th shorter. I'm pretty sure the silver springs are for the takedown pin plungers. What is the black spring for?
HangarTrash on Dec 12, 2018
BEST ANSWER: I believe the one that you’re talking about is the safety selector spring, that sits in the grip and goes through the lowers to the selector detent.
Is the upper T-marked?
Joe T on Oct 27, 2018
BEST ANSWER: The receiver is t marked, but the rail is not.
What’s the rail system like? Does this rifle support under barrel attachments?
Jeremy R on Mar 28, 2019
BEST ANSWER: Yes, it's a 4 sided M-Lok hand gaurd. Use M-Lok attachments to secure bi-pod, light, laser, etc.
Is the flash hider welded or pin on? Can it be change out and if so what thread?
Tommy D on Oct 21, 2018
BEST ANSWER: No, it is removable...just tightened down using a standard crush washer - no pin or weld. The thread is standard 1/2"-28 TPI.
Does this barrel have the roll mark 5.56 1/7 Freedom?
Chris on Oct 16, 2018
Is this the PSA premium BCG?
reyrifle on Oct 6, 2018
BEST ANSWER: In the description it appears to be a Mil-Spec BCG.
Does the upper allows for .223 caliber rounds?
William H on Sep 20, 2018
Is the barrel/gas block dimpled?
Tim J on Jun 24, 2019
I ordered this kit on November 22nd, at that time it was marked as in stock, now I am seeing it is marked as temporarily out of stock, and when I called about its delivery time I was told it would be 2 to 15 days before it ships. The lower has already arrived at the ffl. Can someone give me an idea on when it will be shipped?
Nathan B on Dec 2, 2018
Do I need this kit be shipped to an ffl here in Washington state?
F F on Oct 28, 2018

My last build didn't have a marking on the barrel, but said it was a freedom barrel?
Bobby on Oct 27, 2018

Buy it. You won’t regret it.
Excellent AR15. I used an Aero Precision lower receiver and the fitment is great. Have shot hundreds of rounds with no issues at all. You will not be disappointed!

Great value
For the price it's a fantastic deal - only gripe is the rail. When installing mlok parts (magpul rvg) I had to grind down the screws otherwise they would contact the barrel. However that is pretty minor considering the price point and the quality. About 150 rounds through it so far with no failures.

It’s perfect
Brought it out to the range I work at. Sighted it. No complaints.
I’ve already ran several hundred through it and it’s perfect.
Plan on a couple weekend shoots with friends. I cannot wait!

A major bang for your buck. Great rifle for the money!
Overall great rifle kit for the money. No serious complaints. The edges on the rail can me a bit on the sharper side than I’d hoped for, but overall a great and reliable rifle kit. Would buy again.

Super Happy and looking for another.
This was my very first AR Build, for my first rifle. Im late to the game. The rifle is real nice, aside from a few dings on the top rail, the free float guard moves a tiny bit left to right and there is a bit of wobble when the receivers are mated. I thought everything fit well as I put it together and I couldnt be happier with how it went. Took it to the range and shot a few magazines, the rain put a halt to anything more than three magazines. It shoots very well. Aside from it missing the sights when it arrived it was packaged well and was easy to keep in line while building. Customer service was very helpful getting the sights to me. All in all I love the rifle. It'll be a great tool for getting the kids into shooting. I'm not concerned with the movement flaws, it'll give me something to work on and try to fix, any help on those issues would be great.
Great first build.

Very Good Quality
We bought 5 PSA kits for our first build with an 80% lower. Everything fit very well except for 1 safety/ fire selector which was so extremely tight in all of the finished lowers that it would not turn.
The trigger is sufficient although a see an upgrade in the near future.

Very happy with rifle again.
Very pleased with the rifle. No malfunctions. This is the 3rd rifle I have purchased from PSA and nothing but good quality. My 18” 223 Wylde is a tac driver. Used for hunting coyotes.
Packaging is awesome. Each part of kit is individually wrapped so part’s don’t get lost.
