I forgot to get any softer wire at work today to see if the gas port was clear but should I be able to see some light shine through it into the barrel?
I would start with a very fine sand paper, and when I say just touch it to it I mean like 2-3 quick brushes and then some emry. And yes if you shine light in the gas port u should see something in the barrel.
