Will the mounts be high enough for an AR-15? Expert Answer

Yes it is.

by Todd, Gear Expert, October 6, 2021
I am looking for a replacement scope for my .22LR. I was wondering if this would be a good choice for sniping Squirrels?

This is a neat little set up for anything 22 or 223. This scope will take you well past 100 yards and it’s hard to hit squirrels that far away anyway. I wouldn’t suggest shooting at anything you don’t intend to eat and so the G1 would make a excellent stew starter.
