Ok. I just recently got a Ruger 10/22 for my son's and I to shoot for fun and to spend some time together at the range. I am fine with it as-is right now, but someday want to tinker with it. In particular, I want to swap out the stock as well as install a bull barrel. However, I don't want to spend a king's ransom to do it. Any suggestions on barrels/stocks at a reasonable cost?
