I'm interested in getting my father some kind of rifle in the AR family, as I think he'd have a lot of fun hunting and target shooting with that platform. However, he will only frequently use guns that he can easily carry on his ATV that he uses on his farm (in a hard plastic rifle case he ingeniously strapped on the front of the ATV). Do any of you carry/store ARs on ATVs? If so, what would brand or style of AR is it? The way he carries, I don't think most ARs with 30-round magazines will fit in my dad's mounted hard case.
