Damn nice upper
Pretty nice, light weight upper. Nice hand guard, and fit and finish looks great. Ill put a nickel BCG in and enhanced charging handle and it will be sweet.

First Time Building An AR..
I assembled my lower completely but just wanted to buy an upper I could slap on and this did the trick. I've shot it multiple times with no issues. Literally one of the best purchases I've made. Took a little while to ship but once it did it got to Indiana pretty quick. Can't say enough good things about PSA and their customer service they responded to my shipping questions almost instantly.

What a great deal on this upper. Paired with a nickel boron bolt and CH and this beauty matched up perfectly with my PSA CTR blem lower which I could not see any blems other than a little scratch on the bolt release. I should of bought a few of these when I had the money.

Quick shipping
Great top half to finish my build with fast shipping I ordered it on the 15th of February and received it on the 20th of February the only problem I have with it is couldn't go to the range with it because I was getting ready for work when it came!

Happy Customer
Palmetto you did it again! I assembled this upper to your STR lower build kit and Geissele Super Three Gun trigger. Using a red dot sight I managed 3.5 inch groups using plinker grade steel cased ammo @100 yards. In other ARs using premium ammo cuts this group by half or betterusually much better.Reliability was perfect.
The overall balance and ergonomics of this configuration of parts pleases me. Also the cheekweld is perfect for a red dot using a .83 riser and the trigger is so sweet it feels like I'm going to improve my hit rates and speed on steel targets significantly. Another home run for PSA!
