Re: Zero of ACOG
You should zero the ACOG at 100 yards/meters. You can zero the ACOG at 25 meters/36 yards using the tip of the 300 meter aiming point but this is to get a rough zero only, you should confirm at 100 when possible. When using the short range zeroing method, being just a little bit off at such a close distance will magnify the farther out you go.
