On a 16 1/2 inch barreled AK style weapon shooting standard 7.63X39 FMJ ammo what is the recommended zero distance to be good out to 100 yards with a 512 EOTech HWD? Thanks for any help......Trapfan

Bingo, and note the remington.com ballistic charts are good for many calibers but show drop from the BBL not the sight line. Note that 7.62x39 drops fast at 150, similar to 5.45/5.56 at 250.

From bore center to center of tombstone on the EOTech is 2 7/8ths of a inch. Only expecting to hold 4 or 5 MOA at 100 yards with this set up. Shooting 122gr surplus FMJ rounds.
