You don't find me in the rifle area much - mainly as I know spit about rifles. About a year ago I picked up a very nice Rock River AR carbine just to have one. When I asked my rifle buddies about optics - they all said ACOG. Since most of my rifle buddies are soldiers (that have used them in combat) I figured they knew their stuff so I found an ACOG at a good price. While I was in Hawaii (for my son's surgery) I picked up an EOTech 512.A65 for cheap and I was wondering how they compare. I'm not a long distance shooter and I use my AR (not often enough) for plinking at 100 yards or less. I've never even installed the EOTech so I'm just wondering about the merits of each as I'll probably sell one of them. So - which would y'all prefer for 100 yard (and less) plinking?
