nylon 66

Hello, new to the forums, but I've got an issue I'm looking for some help with. I recently acquired a Nylon 66 from a friend. However, we've been having an issue with feeding. I partially disassembled and cleaned out a ton of junk, to no avail, same problem. The first round usually chambers...

I bought a Remington nylon 66 a couple days ago and completely went thought the gun and cleaned it, (Looked like it wasn't ever cleaned, took 4 hours) I am having problems with the bullets not ejecting out right and getting cough up on the bolt. happens almost every time if not 1 out of 3 shots...
