Faye M on Nov 14, 2018

How come everything says full auto ?
Tronmattamy on May 20, 2019
BEST ANSWER: It’s referring to the bolt carrier group and the standard that it is built to. It does not make the weapon fully automatic in any way.
Is the hand guard cap circular or triangle?
Hunter S on Feb 17, 2019

Is the stainless barrel an upgrade?
Larry M on Mar 19, 2019
BEST ANSWER: Usually it is a upgraded part. In general they offer more accuracy, longer barrel life and are easier to care for.
is the barrel 16" with the flash hider or without?
Natural9er on Feb 23, 2019
BEST ANSWER: All the 16 " PSA barrels I have purchased, have been a full 16 to the threads, so the muzzle device, whatever it might be, extends beyond 16"

My new favorite toy !
I love it.. It was a snap to assemble and shoots perfect. I left it open sights for now and may add a dot scope later.

Thanks PSA, Your products and pricing makes me a dedicated customer.

Works like my Colt but cheap enough to go where I go. Made a good truck gun. 100% reliable so far.

Excellent quality, very happy.
Not many people mention that PSA checks and test fires complete uppers like this prior to shipping, so don't be concerned when two weeks pass by before it ships. That would be the only downside (if QC is a downside) of my personal transaction. Excellent product, perfectly matched an Aero lower with outstanding fit. You will definitely need an armorers tool, vise, holding blocks to break the barrel nut, they are tight but not impossible. Just throwing that out there for other first time builders. Very happy and will definitely purchase from PSA again.
Stock kit with Aero lower.
What floats my boat.

Give it a three star.
Over looks good but they haven't changed who makes their uppers and the fit is not that great. You will need accu wedges.
