I would agree with this unless I had a ton of X39 ammo and was set up to load it already, the Blackout and Legend work better in the AR platform. The Blackout isn't a 30/30 but it's a good short range deer rounds. The Legend in an AR is absolutely the modern equivalent to a '94 30/30.I like my ruger American Ranch in 7.62x39, but if I were still in the consideration stage.....I would consider a .300BO or .350Legend in case I got an opportunity to hunt in a "straight-wall only" state.
