See, all the times I've had an EOTech on a rifle, I've never once noticed the circle when I was actually using it. IMO, it's too damn big to really use as a rangefinder - you're already talking a 10 foot tall object (or 5 feet from reticle to circle) at only 200 yards, which is close enough you don't need to know if it's 150 or 220.
The cheap POS Millett scope I ran for a while had a 10MOA (at 4x) ring that was somewhat useable for that and bullet drop.
