I have two questions:
How in the world do I headspace an RPD? I have a new barrel kit from sarco, and in order to close the bolt fully, the barrel has to have the slot for the ejector milled out, but how do you know where to mill the ejector slot if it's not headspaced? I'm missing something. Can anyone help?
My second is: What is the slot in the barrel for ejector shaped like and what bit would I use to cut it. I think a picture would be worth a thousand words to ancewer this question.
