Built a M16-A1 clone from parts. I kind of remember from Boot Camp (USMC) 12 Clicks out of the bottom for the front sight post & 13 from
the left on the rear sight. Was this Battle Sight Zero or my 200 yard basic zero? Been on line & have seen the way the Army does it but in the
USMC we qualified on a KD Course. Looking for a 200 yard Zero & been almost 40 years since I fired an A1.
Thanx
