I've got 2 Mosins and an SKS that I've never fired. I've picked these up from some folks I know and would like to have someone check the headspace and general fitness before I try to fire them. The SKS was dropped into a Tapco stock and the Tapco mags don't seem to be fitting just right. Any recommendations on a gunsmith in the OC area that won't charge me a ton of cash to do a safety check? Someone suggested Gun Broker in Clackamas, but I haven't checked with them myself for this service. Anyone have experience on the gunsmith side with them?
