I've got a PSA-10, and am having the exact same problem with the rifle ejecting/with the exact upper. After reading/skimming through this forum I have two questions before I go and spend money.
1. Was there a reason you took the Fulton Bolt out and just used the Palmetto with a Fulton Extractor?
2. Would the Fulton Bolt be fine? Or is there a different bolt that is recommended? I've noticed Palmetto won't say what style bolt they are using and just say it's proprietary.
I'll be ordering the true rifle length gas tube as well. Anything else I should consider or might have missed?
