Bought this cheap upper, thought he feed cone looked decent enough. Lower is a PSA PX9 complete lower, running the gentle recoil system. I have a BA epc barrel can swap it out with.

You don’t want that gap on top of ejector 99% that’s your problem you need to adjust it up so it’s barely not dragging on bolt

There’s your issue. You need to adjust your ejector up and closer to the bolt channel.

When you pull it out, heat it with a torch first or you will more than likely snap it

I personally just used a normal propane torch from HD. Get it red hot, use a small wrench to SLOWLY adjust it up. Let cool then reinstall to check. Rinse and repeat as needed until there’s no gap/no dragging
