Have a couple rimfires I've been using over the years, love the Ruger 10/22, but thinking of moving up to a centerfire. I don't hunt, just drop by the range when I can for target practice. See quite a few AR style rifles when I'm there but not familiar with them. Do you think switching over to a SR-556 would be a more drastic change than one of their Mini-14s? Didn't know of people preferred one over the other because of style, personal preference, accuracy, cost of upkeep, etc.
