Thanks for the info I really appreciate it . I live in the country where there is actually a range out to 1200 yards where my good friend shoots and teaches long range shooting. My uncle is recently retired as a counter sniper for the president so the learning curve should be much shorter I have shot bolt guns a ton and never really had a ton of interest in ar style rifles until Obama said they were bad ;). My budget isn't huge but I think I can still build a great gun. Not that I'm rich but the wife gave me the blessing to build a really good gun . I will check into the rra never heard of them
