Nice upper receiver, I wished it worked correctly
I have had problems since day one with the upper receiver ejecting spent rounds. We played with the gas block and finally after much frustration sent it back to Palmetto. The gun smith tweaked it and once I received it back I was able to shoot approx 40 factory loads without it jamming but it soon started the same problem again. Adjusting gas block did not help. My lower receiver is a Palmetto brand that works excellent with my 223 upper. It won't correctly cycle a hand load ever. My nephews 224 made by another company works just fine. I am sending this upper back to Palmetto again. I want a new upper that actually works. My prairie dog shoot was a big let down as I had planned to use the 224 a lot. Thankfully the 223 upper was working just fine with my hand loads.
On a positive note it is accurate when it does cycle, and I love the look and feel of it. Just can't get past it is not at all dependable.

Impressive upper!
Wish they would get more in stock cause I would buy another one. Light weight and looks amazing. Functions flawlessly on the lower I built. Would definitely buy it again.
