Has anybody built on of there own? I own a few and am wanting one for a .308. I have all the paperwork ready but I am unable to find any kind of blueprint or design of anything modern. I have found plenty of older stuff but I do not want to build any of those. I can get general information from the websites of the company's that make them IE size weight and such. However the internals are where I am coming up dry. The modern ones I do own or .223 an 22lr. is building the .308 just the same internals just bigger? Anybody with any information or blueprints please shoot me a pm.
