? about a BCG

Is the ejector moving freely? If the ejector is jammed with shit it wont throw the casing making it seem like it's not getting enough gas. I would also remove the gas key and check out whats going on there. Just restake the screws when you reinstall the gas key.

I recently had the ejector freeze up from brass shavings and at first thought it wasent getting enough gas to cycle. Deffently give it a look before taking the gas key off.

Here are a few pics. I will look over ejector
