What are your thoughts on BZO? I always like to hear opinions on this, because I hear so many different methods from different people.
In my limited experience, I was taught to BZO at 50yds. Others say 25 yds, 100 yds, 200 yds, etc....
What do you say?

Army BZO is mechanical; basically center the windage and lower the rear elevation flush with the carrying handle and 3/6 alignment, front sight post base flush with the hole.
USMC BZO is fire for zero.
That said, the Army fires for zero before qualification/training/combat. In fact, I have never used a mechanical BZO; it is emergency use only. The mechanical zero is for picking up a weapon that you have never fired (e.g. battlefield recovery).
We use a 25m M4 paper target and 3 round groups to zero. Fire 3, check the target, adjust the sights. Rinse and repeat until your shot group is centered. That should put point-of-aim as point-of-impact at 300m. It works for me.
For other weapons systems, I am sure that there are other zero targets.
