Ok guys, for the ones who know me, they now I Pimp out my kids guns. My question is for my sons AR that i'm going to build for him, Im looking at putting a Trijcon Acog on it, at first, he will be shooting between 25 and 100 yards, but i'll be using it to help teach longer shooting. I know baby steps first. Ok, you guys got me, its also for when he is not shooting and i'll use it. Any thoughts on the different models out there?
