Thinking of building a rifle and am fairly new at all of the custom options. The bighorns get some good praise and am thinking that is the way I would like to go. From what I can tell it is what they are made out of and pinned vs integral recoil lug are the differences. What is the real advantages of those two things? I am on a budget but would just save longer if the tl3 was worth the extra money. The goal is to use prefit barrels and thought I saw that the tolerances are tighter with the tl3 for this but I could be mistaken. Thank you
