What is the overall weight as it is described above (including BCG)?
JF090 on May 18, 2018
Is this 4150 or 4140 steel?
Kevin F on May 16, 2018
BEST ANSWER: It is 4150 and it’s best price and quality parts still putting rounds down range and haven’t had any issue so fare
If I have a PSA complete lower that I purchased, would this be all I need to an complete an AR? I've never built our built one.
keith c on May 14, 2018
BEST ANSWER: Yes. Has mbus sights and everything. If you wanted a red dot sight or scope, you’d have to add it. But as it sits, it’s everything you need.
Can you attach a vertical grip?
Justin R on Jun 6, 2018
BEST ANSWER: Only if it is M lok. The holes are at the bottom for it.

Thomas H on May 19, 2018

Shoots fine, barrel nut is torqued unbelievably tight
Shipping was quick as usual. It shot well, but my intention was to be to swap the barrel, which I do quite frequently with my guns. I'm not sure what spec PSA tightens barrel nuts to, or what kind of thread locking compound they use, but it's almost as if it is welded on. I can't count how many barrels I've swapped over the years, and I've never in life had one that I couldn't remove with an adequate amount of torque/force, until this one. I figured I'd do the same thing I always do, throw this in my upper blocks, put that in the vise loosen it for a quick swap. Well, I tried every trick in the book to get it loose and after multiple attempts, the upper ended up cracking and the barrel nut didn't even budge...Ok, well since the upper is now cracked, I figured I'd do away with using the upper vise blocks and just have a go at it with the upper directly in the vise.....same results. So now I have a PSA paperweight. If you plan on just keeping this upper assembled as is, you should be good to go, as it shoots fine, but if you plan on swapping barrels/upper receivers, you may just want to buy the parts separately and assemble it yourself.

We do apologize for that. If you run in to a situation in the future where the barrel nut is over-torqued, we can have it brought in and our repair team can remove it for you.

Very good product. Best bang for your buck. Highly recommend this rifle.
I was very impressed with this upper receiver. I expected it to jam at least 3 or 4 times. But it didn't. It was easy to breakdown and lube up the parts. It shoots pretty smooth with very little kick. The Mag Pul sights took 6-7 rounds to zero in on stock settings. Its good for 300 meters or less. Beyond that you'll need different rear sights or scope. Love the pop up sights. Press a button and bam they pop up for close combat. Only negative thing is that stock grips dont fit this. Well the few that i tried didn't work. But a few gun smiths said they can add some rails or whatever it was to install grips, flash lights ect. In all this is a good complete upper for the price you'll pay. My complete set up was less than 550. Including my clip. Most complete rifles ran 590 w/o a background check for those who don't have a CCW permit. When I first shot it i was surprised at how little the kick was. But the bottom line is this is an amazing upper for the price. I highly recommen buying this, made with good quality parts and will continue to buy more of my uppers and lowers from palmettostatearmory.
It was pretty hot that day. So after  the rilfe was zeroed in. I rushed the rest if the rounds.
The barrel shoots very accurately. Very good groups. When I took my time.
Pop up sights are excellent if your just going for 300M or less.
The factory sights are pretty spot on striaght out of the box. It took me 6-8 rounds to Zero her in.
