What lower receiver do you recommend for this upper kit?
Jarod B on Apr 27, 2018

shawn h on May 12, 2018

I was just wondering, with this kit, is it everything i need to put it together, or do i need anything else, this is my first one, an dont want to get it wrong?
Thanks
mustang8750 on Jul 14, 2018
BEST ANSWER: Everything in this kit is what you need to build/assemble a rifle on a stripped lower receiver. If you don't have a stripped lower, PSA sells them, or you can purchase from a supplier of your choosing. That will require the lower to be shipped to an FFL holder. These kits are good quality and easy to assemble. Check out some assembly videos on YouTube for instructions, tool choices, and if you even want to go down this road. Some optics would be needed as well. The pop up sights provided are more or less back-ups to some good optics. Good luck and keep the RPMs up on that 5.0
Is this a complete build or just the upper?
Nick M on May 14, 2018
BEST ANSWER: It is a complete build kit minus the lower receiver. The upper will come assembled.
Is the buffer tube Mil-spec or commercial?
Nathan on Apr 29, 2018
BEST ANSWER: Mil-Spec diameter buffer tube.
Has anyone had any problems with certain Ammo running through this upper?
Matt S on May 11, 2018
BEST ANSWER: No problems so far. Got about 500 rounds through it shooting federal, winchester, hornady and even tula and aside from a few dud rounds of tula everything worked perfectly.
Is it possible to get a lefty version of this?
Jay Wells on Apr 27, 2018
BEST ANSWER: I'm a lefty and used M16s in the infantry. Once you use them a bit it seems like they are more suited to lefties than righties if you change to an ambi safety! Bolt release with trigger finger, mag release with thumb of non firing hand when changing mags. Can't use a left handed AR now. Feels backwards!
Can you use .223 ammo with this rifle or just 5.56?
bcowboi on Aug 4, 2018
BEST ANSWER: Either one it is multi caliber
Is the barrel mil-spec?
rval093 on May 9, 2018
BEST ANSWER: Yes it is! I’m very well satisfied with this rifle kit.
It it hbar or does it have a pencil barrel?
Wyatt B on Jul 27, 2018

Perfect
Exactly what I expected and works like a charm. The upper is pre-assembled and comes with the Freedom barrel for any who weren’t aware. I bought an Anderson stripped lower and everything fit just fine once I got it assembled. Looks cool and shoots straight. 10/10.

If you’re new to building, consider a set of roll pin punches. I learned a good way to increase the challenge is trying to assemble the lower with a screwdriver and hammer.

Great Kit
This is my sixth build using PSA parts. This rifle performed flawlessly. Shoots great throws the brass in a neat little pile. I have never had a single issue with any PSA parts. Buy one you will not be disappointed.

Great quality at the lowest price
This is my first AR build and I couldn’t be happier. I married this to a Bushmaster lower with the PSA lower parts kit and a Holosun red dot. After looking around for a month I really don’t think I could have found this much quality for this price anywhere else. I’m already trying to decide on the parts to my next build.

Love it
Recently purchased these parts, put them all together. Took it out without a hitch. Shot well and only took me 3 adjustments to dial in the sights. I would purchase another kit

Impressive for price.
While I have not shot this gun yet, it is impressive looking so far and very light weight. I like the look so far, will no more once I hit the range.
