I took a FN PBR .308 in on trade and im looking to start building off of it but the bolt has pitting on bolt and i was wanting to know if this could be fixed relatively easily. Also i have never done any but buy factory guns never dealt with custom or semi custom rifles. Would this be a decent gun to start building off of? Im not going for anything over the top and would like to build a decent shooter with a budget of like 1000 to 1,500 on the gun not including glass. So my main question was is the m70 action decent to build off of for that type of budget and can pitting be fixed on a bolt. I can get pictures of the pitting if that will help.
