I have one w/ a Holosun red dot mounted on my AR. And I did a Carbine class locally weekend before last.

I had a lot of trouble adjusting my holds from 5 yards to 100 yards. Everything except the 25 yard (my zero) was off more than I'd like.

Anyone have particular experience with this setup?

What's your zero and how quick do you find adjusting to the holdovers? Right now, I'm leaning towards adjusting to a 50 yard zero.
