I have a friend offering me a custom 308 remington 40-x with shilen stainless barrel but the bolt has gas cut in it and not sure bout the barrel and throat erosion i have inspected the barrel and looks good but buying it is scary due to the fact that the bolt isn't that great of shape the weapon has a bench stock and is single. I'm tempted to buy the damn thing the price is right but would like to get some insight on it, the price 500 -700 just hoping to get some useful info.
