It can have its place on a 5.56 AR in my opinion. Some three gun stuff will have targets out far enough that you would love having a scope over an AR and to my the mildot reticle is just a preference thing for a lot of folks. Where we mostly shoot all of our targets are 60 yards or closer so it’s not necessary for me. Right now the big trend is recon AR builds. LPVO optic with a mid length barrel. Wouldn’t be a bad set up for a SHTF rifle. Throw an offset or top mounted red dot and you are set on anything from CQB to 500 yard shots.
