Just because you paid less doesn't mean you will get less(quality). PSA cuts out the middle man!
Great priced rifle, excellent quality do not think that just because you are paying less you are getting less Palmetto State Armory cuts out the middleman so you can get the same quality if not better than other manufacturers that charge hundreds more.

Great buy.
Recived the rifle within 2 weeks and the first time I shot it the empty caseings wouldn't eject properly and kept jamming up. Sent the BCG back and got a new one another two weeks later and worked just fine. Great price for my first rifle.
February 28, 2019
So far so good. I've put 500 rounds through it so far without a hitch. Delivery was quick. Tight fittings. Great looking gun. Only complaint would be the trigger is catchy, which i'll upgrade eventually. All in all love it.

Great looking gun. Had to sell it the week after I got it. I'll deal with other people's paper mistakes and buy another. Seems like a solid firearm. Going to get a nice optic for the next one.
