Good quality and a very fair price. One satisfied customer here.
This is my first AR pistol, and I am very pleased with it. I've only shot 90 rounds through it so far, but not a single malfunction. And it's accurate enough at close range to make an excellent home defense gun. Will probably add a weapon light to it. I think I would have a hard time getting a better product for this price. Thank you, PSA!
My first AR pistol and I'm loving it. Not a single malfunction so far.

Great price on a nice upper
Upper functions flawlessly I've put about 300 rounds through it without a single malfunction. Runs my reloads(55gr jsp) great. Only bitch I have was the flash hider was scratched to hell looks like it was installed with pliers. Oh well I switched it out for a kak mini flash can and love it. Great buy and I would buy it again.

8.5 pistol
Again perfect fit and function from PSA ! ONLY 2 complaints 1st is it was very stiff charging which disappeared after the first fifty rounds. second complaint has nothing to do with PSA i used a anderson lower and i wish there fire/safe stamping was deeper ! I should have used a PSA lower my bad!

PSA keep up the good work !
