Exceeded expectations
I bought this upper as a budget build in total I spent just under $800 on this AR first day at the range I shot 100 rounds of 55gr federal factory ammo through it to break it in. I was getting very consistent 1" groups at 100yds and even some 3/4 groups. At first the bcg was a little rough and had to hit the forward assist a time or two even after lubing it up though about the 50th round it started to slide very smooth. After dialing in the factory loads cleaned the barrel and ran my 55gr and 62gr hand loads groups tighten up to 1/2-3/4" and at times even stack 4 shots in the same hole all in all this is a fantastic upper couldn't be happier.

I received this upper today. Went to the range fired 5 rounds to get to the bullseye at 50 yds. I then proceeded to fire two groups of three at 50 yards that were each about 3/4 inch group. I used 5.56 ammo no failures to fire or extract. I used Magpul gen 2 back up sights as that is what I will use for the sights until I can get some optic for it. Very smooth shooter it was paired with a PSA Magpul lower which has a gritty trigger but I've used worse on a Colt. I was very pleased with it. This is the fourth AR15 I've put together using Palmetto State Armory parts. I've had excellent luck with the exception of one trigger that didn't want to reset consistently too rough. A little love and it runs like a champ now.
