I'm considering piecing together a .308 bolt action rifle using a AI AX Chassis and maybe just buying a Remington short action and barrel. How difficult would this be? I've never attempted this before, but would rather learn more about the rifle and how to build one, rather than forking over 1000's of dollars and learning nothing. I am going to start my research but thought this would be a good place to start looking. Any advice is great and would be very helpful. Thanks in advance for your help and time.
