AAAARRRRRRRRGGGGGGGGGGHHHHHHHHHHH!!!!!!
There seems to always be massive confusion about the use of the ACOG reticle.
For CQB work, you put the triangle on the target and pull the trigger, period, just like you do with an AimPoint. It doesn't matter if you're using a Donut, Triangle, or Chevron.

NOTE: top line distances should be labeled:
100m, 100m, 200m, 250m, 300m
Due to the trajectory of the bullet, the bullet will pass through the center of the triangle (or other reticle) at 50 yards, touch the tip at 100 yards very near the bullet's apogee, cross the center again at 220 yards, and cross the bottom at around 300 yards. Note that at 300 yards, the widest part of the triangle is still less than the width of a person.
[red][b]At 300 yards and beyond, you'll be using the ladder portion of the reticle, so the shape of the BAC reticle is irrelevant![/b][/red]
These are [b]combat sights[/b], not target sights. The BAC reticle is designed to allow you to make FAST hits on a human-sized figure out to 300m, not to make .5MOA groups. If you want a scope for .5MOA groups, us a TA01 or something else with a conventional crosshair reticle.
IMO, the WORST of the BAC-equipped ACOGs are the ones with the fat BAC cross-hairs. I find these adequate for shooting at paper targets, but absolutely abysmal for shooting at real-world targets ("dressed" pillows representing bad guys).
But, hey, that's just my opinion, I could be wrong.
