There are some real nice AR type guns available these days but they're on the heavy side if you'll be doing much walking.I use the CZ 527 American in .223.Just got it near the end of last winter so I only had about a week of coyote season left.No luck but it wasn't the guns fault.It's a great shooter right out of the box even with low cost ammo.With the reloads it's a tack driver.
