I'm new to the whole rifle world and just got a .308 SPS Tactical for Christmas and I'm reading on here about all this action blueprinting and "lapping the lugs" and "squaring the front end of the action" and what not, but to be honest I know nothing about all these terms. As a matter of fact, I don't think I could explain what the action of the gun is if I had to. I know I could probably google the basics, but I was wondering if anyone knew of a good source that started at the basics and worked into all this stuff. I'm wanting to build my rifle up to be as accurate as possible but I'm the type that I like to do all my research and actually know what I'm looking at and reading before buying parts and upgrades just because it has high ratings on midway.com or this person tells me I need this and another person tells me I need that. I like to get all my facts and knowledge-base first. Thanks for any info guys.
