.x39 ARs are usually accurate. Ammo is everywhere. Must use mags just for x39 in the AR. An AR in x39 does not use AK mags unless you have a lower that specifically uses them. X39 ARs use a different bolt than 556 guns. 300 BO uses the 556 bolt and mags. Only requires a upper/barrel change. If you want to run the same lower as your 556 AR is just a bolt and top end swap. 300 BO ammo isn't a walmart item. However, places like Academy sometimes stock it. Still, you're likely to order ammo for the 300 BO. 300 BO is probably just as accurate as x39 in an AR. X39 will cost you more to get into that the 300BO, but the x39 is cheaper to feed. When you decide you hate your 30 cal AR15, the 300BO will be easier to sell.

If you're a hunter or prepper type looking for a 30 cal gun that makes that kind of power and is cheap to feed, the 30-30 is more versatile and easier to carry. Personally, I'd spend my money on a lever action in 30-30. I've had ARs in a variety of calibers including x39 but not 300BO. The only ones I've found a real use for is the 556/223, 6.5G or 6.8SPC guns, and the 450 Bushmaster.
