I can see putting a scope on a AR but no need for a big one .
Eye of the beholder...
I have an AR varmint build with a 4x12... sure could use a 6x24 or some such.
my eyes are 59.
I still need nothing larger than a 10 pwer out to 300 yards.
My eyes are 66, I have macular edema... used to need 4x12 to see beyond 100yds, now I'm not sure as I haven't shot rifle since my eyes went south. Even had to shoot my pistol cross-dominant so I'm not looking forward to shouldering my rifle right handed and shooting with my left eye.
This thread reminds me of an old joke I heard when I was a kid.
"White men build big fires and stand far away, while Indians make small fire and sit real close"
Racist bastid!
Let me see if I got it: White man shoot deer at 3000yds, Indian sneak up and slit throats. Indian have less of a walk, white man use 4x4 to fetch up dead critter.
