Love it!
I wrote a review and accidentally closed it so this one wont be as long. All in all the gun was great. I've had no issues and it looks amazing the barrel guard isnt thick so it's easy to get a good grip around it even with smaller hands. Runs good, sights are great bonus, shoots good and was on sale for about 365. Love the gun and bought a second one for my father. Paired it with a palmetto state armory stripped lower. I got the buffer tube and stock and lower parts kit from cheaper than dirt.

Meets expectations again
This is the second upper I have purchased form PSA. This particular one is very light and ran like a champ on the range. No issues joining to an 80% Lower. I’m very happy with it.

Would and have recommended this upper and PSA in general to family, friends, and co-workers!
Great fit to the PSA lower nearly no movement between the two. MBUS sights work great! Nice little bonus with this upper. Charging handle leaves a bit to be desired, but already have an upgrade on the way. Shot groups with 55gr and 62gr could be better. Looking for a 1:8 twist barrel now. That ought to tighten up my groups. Would be nice to see a little more selection in barrel twist rates as not everyone understands how twist rates affect rounds or has the tools to swap barrels, but overall great purchase for the price! Nobody does $500 ARs like PSA! Love the extras PSA hooks me up with.

Crazy Good
You cannot get a better deal on a high-quality professionally assembled upper period, AND with a Carpenter 158 BCG AND Magpul sights - mine came with a Midwest Industries rail. Unbelievable! Talked a family member into a buy last week too (his first AR) and I am confident he will not be disappointed. Not my first PSA build and - disclaimer - I had a problem with one. Best part, true to their word they fixed it for free, sent me an apology letter (not a robo-letter either) and paid all the postage. "PSA" is becoming increasingly the majority in my gun safe. Shot this one this weekend sighting in at 100; in the bull within 20 rds. with a red dot sight. Only question for me - where to fit the next one (running out of space in the safe). Keep it up PSA, great quality, fast shipping, awesome prices.

Fires great. Looks great. Feels great.
I've ran 200 rounds through my ar 15 that I built with Palmetto state upper and lower and I haven't had any issues. Looks and feels great. I love it. I would recommend it to friends and family.
Complete Palmetto state AR15 build.

High Quality Upper
Very impressed with the quality of this upper. It holds a tight group as well. I would recommend PSA for anyone looking to get into AR platforms without breaking the bank.
