I'm new to builds. Can this upper work with any AR lower?
Mark F on Jul 18, 2018
BEST ANSWER: It will work with any standard/mill spec lower. However the lower must be a pistol lower with a pistol tube or brace, unless you have a registered “short barreled rifle” (an SBR is a rifle with a barrel less than 16”).
Are the MBUS sights polymer or metal?
JONATHAN F on Apr 20, 2018
BEST ANSWER: Polymer. Google and you will see the diff.
Is this upper shipped assembled?

Good Upper for the Money
No real complaints with this upper from PSA. It was attached to a pistol lower and ran hard from the start. Ran smoothly and no noticeable issues other than the included rail is heavy. This pistol ended up weighing more than my full size AR with 15" rail. Something to keep in mind if you're going for a "lightweight" build. I was not, so no real issue for me.

Perfect upper to match with PDW lower build kit. Fit, finish, and quality you can not beat Palnetto State

Another great PSA upper.
Great upper. I love the handguard, and that it came with sights, bcg and charging handle.
I have a couple hundred rounds though mine and it's had no issues. Its very consist and accurate, thought 300yards is a pout as far as I've had it out too.

You really can't go wrong with PSA

My reviews are going to look pretty repetitive, but that's cause I have the same good things to say about these guys...

-They consistently have the best prices
-They have quality products
-They have a great selection uppers, lowers, kits, and complete rifles
-They constantly have great deals on accessories like optics, mags, and range bags
-They always have good prices on ammo in bulk, and often with free shipping

Idk what more you could ask for. 9/10 times these guys are my one stop shop and I recommend them to anyone looking to buy/build an AR

Excellent, reliable, affordable.
Overall, I was surprised with the quality for the price. It was awesome to receive it in such a timely manner, especially because PSA uppers are typically the longest shipping time of all of the things offered by PSA.

Very happy with my new PSA 5.56 pistol upper!
This was my first purchase from PSA. Order was shipped out to me the day after purchase. Packing was excellent! Upper was added to a PSA complete pistol lower. So far I have 250 rounds fired from four different manufacturers 55 grain and 62 grain and every single round went bang. Pistol is more accurate than I am . This is a life and liberty pistol and is being carried everyday in my EDC backpack. Couldn't be happier with this purchase and would definitely recommend to everyone. Added bonus is PSA is a veteran owned company and actually supports the 2nd amendment.

Do not think about it too much. Pull the string and go for it! You will not regret it
Extremely content with my 10.5” PSA upper. Very comfortable, provides great real estate for accessories and looks great. Definitely not my last purchase from palmetto state.
