A quality rifle at a budget price
I was a little hesitant buying a Palmetto State Armory AR because of the ridiculous sales they have. I assumed it was going to a budget rifle. Let’s just say I would definitely buy another one. They are quality rifles.

Response from Palmetto State Armory
Thank you for commenting on your recent purchase. Many people incorrectly assume our low-cost firearms and parts are because of low quality. The truth is we control all facets of production, sales, and distribution to you to cut out all the middlemen that drive the price up before it gets to the customer. Additionally, you can save more on your next purchase by buying the upper and lower receiver separately and putting them together yourself, this will help you avoid a 15% tax by the ATF on the sale of a complete firearm. Thank you again for your purchase and happy shooting.

Great bang for the buck
I have yet to shoot this gun as my schedule has been busy. Based on build quality and looks it is a great made pistol. I will come back to this review and edit after my first range trip. I have included 4 pictures of the pistol after a few accessories.
Changed grip, added mbus sights, red dot, front grip, mlok covers

Haven't shot it yet, but the build quality is great. There is a noticeably tight tolerance typically seen on more expensive firearms. The build quality is above and beyond that of my DPMS oracle that was the same price. Ordered Midday Monday and had the pistol in hand from the FFL Thursday afternoon. Super fast shipping.

Sweet action
Love it! I had been wanting a shorty for a while and came across this beauty. Added an optic, back up iron sights, and a finger stop on a partial rail, turned out super bad ass. 10/10 would recommend.

This thing is AWESOME!!!
I bought this PSA pistol because of the price. I wasn't expecting the great quality. I have been thoroughly impressed. I've fired 300 rounds with NO hiccups. This gun is so much fun to shoot. I put a Sig Romeo red dot on it and I carry it in a briefcase. I will say the 5.56 with a 8.5 inch barrel is LOUD!!! I'm going to purchase a 300 blackout upper so I can add a suppressor. Get one, you won't be sorry.

WOW! Love this thing.
Picked up this tiny AR and there are no regrets. I was worried with 8.5 inch barrel there would be cycling and accuracy issues. I've put about 300 rounds through it so far with no malfunctions. I installed a Vortex Strikefire 2 red dot and sighted it in for 100 yards. No problems hitting the 12 inch steel at that distance every shot. Only negative is the grip, not very comfortable. Will be replacing with Magpul grip.
