I want to get my new to me M14 tuned up. Whos the guy to talk to in the fraser valler, lower mainland, greater vancouver area. I usually do my own work but after all the reading I can do, things like head space and gas chamber shimming are a little beyond me I think. I want to get this thing running like a champ, accurized and so on. Excuse my lack of knowledge on this rifle. Its my first M14. Thanks.
