I’m a big fan of the 18” MK12s. They shoot like a laser beam. If it’s not going to be your only AR, I’d say go for it. For the longer ranges you’ll love the accuracy from a good barrel. I wouldn’t want to tote one around all day for a class though, they tend to be a little heavy. ARs come in all sizes for a reason.
