What does the brass er, steel fired cases look like? A rough chamber can retard ejection.
Acquire/make some dummy rounds and cycle by hand. If that test seems normal then it would seem there is not enough energy in the system.
Either not enough gas (gas port alignment or gas tube problem) or to much resistance of the bgc moving rearward. It may need lots of lube or a reduced buffer spring or buffer weight.)
OR it could be to much gas. I've read some forum threads that put forth that to much gas will let the Bolt unlock early before the case can contract, so that it sticks to the chamber, making it much harder to extract, slowing the BCG down and thus weak ejection.
