new BCG rough hand cycling

[Iraqgunz]

I would replace the screws with quality ones from Colt and then re-stake with a MOACKS or the field staking method.

Is there a known problem with the gas key screws? It looks like one is marked "fmx" and the other is blank. The staking was very light and in between the screws outer edge and the key, so I added side stakes with my auto punch.

I am curious. Why would you put a BM BCG in a BCM upper?

I really wish guys would either ask the board, or find a few people who knew what they were talking about and ask them.
