What kind of sights will work with this upper? Can you put a red dot on it?
Mikie on Jul 12, 2018
BEST ANSWER: I put a Holosun red dot on it. It works great. Any red dot will work if it is high enough to 'co-witness' with normal AR sights. You can purchase a flip up sight for the rear.

PSA Freedom Rifle is a Winner
The Palmetto State Armory "Freedom" Upper, combined with their "Freedom" Lower make for one great, accurate rifle.

There is no beating PSA's quality for the price point. Several trips to the range later, the rifle cycles flawlessly with ZERO malfunctions.

Very nice upper for the money.
I changed out the gas block for a low profile one. Bought the matching lower. Great little rifle for the price. I would order again with confidence.

Price do good I can customize it.
Great deal. Nice looking piece. Haven’t built it yet but intend to cut down the A2 sight to use only the gas block under a free floating hand guard. Price was so good I figured the handgard could be replaced and I would not shed a tear. ♦️

Great Deal
I picked the upper and lower up will on sale. the fit and finish is outstanding on both. I have only put 400 rounds thru it so far, but it functioned flawlessly. There is no better deal out there. $348 for a great AR-15. PSA is a great company to do business with, they make quality products that are at a great price point.

Great piece
Great piece for the money great finish and fit thank PSA up grade the hand guard.
July 24, 2018
Good overall, but not perfect.
The finish was great and feels solid. I installed it on an Anderson lower and it fits great. Interestingly, it will not fit my dpms lower as the rear take down pin hholes off by a hair (my dpms upper also fits the Anderson lower great). I am going to replace the hand guard and the stake job on the bcg leaves much to be desired. Overall it's great for a budget build though it may be best to find one without a bcg so you can buy a better one.
