1. Shoot irons for a 25m-300m zero. Point of aim at 25m is point of impact at 25m and 300m

2. Mount red dot optic of choice.

3. Co-witness red dot to irons sights.

4. Confirm red dot zero using ammo.

5. Mount IR Laser sighting device (PAQ4, PEQ2, PEQ15).

6. Put on NVG, set red dot to NVG setting.

7. Co-Witness red dot with IR Laser at anywhere from 100-300m depending on range you have, 300 is most preferred (using NVG looking through sight).

8. Confirm IR Laser sighting device on paper if you feel it is necessary with the 25m target using ammo.


If you do this right and you don't shoot like a shotgun on crack, you can do this with about 20 rounds per man.

Biggest problems ever seen were operator headspace and timing, ensure all sights are tightened down (#1 problem!!), ensure you know what each click on whatever sight you are using will move that sight at 25m. Know that 1 moa at 25m is a 1/4 inch, therefore 1/2 moa adjustments on your sight will move the bullet 1/8 of an inch at 25m.

Shoot 3-5 round groups, I prefer 5, the Army says 3, I say FTA and do it the way I know works, but that's just me, the bigger the group, the better the shift. Measure from the center of the group for moving the impact.

10.5's that are brand new shoot rather well at the range on the first day, just be sure to confirm those zeros ever few ranges, the sights can get quirky after a couple thousand rounds through them, I have seen up to 4 or 5 moa shifts from one day to the next on them, it was usually an EO Techs Fault though, the irons held true for the most part.
