To those of you that have ARs carried in the cuiser and used by several different officers, what procedure do you use for zeroing?  Does an armorer or instructor do the zeroing and everyone else is "close enough"?  Presently thats what we do, but there's got to be something better.

                    Thanks

When we went to carbines in the car every officer was assigned a carbine, and did his own 100 yard zero, and had to qualify with it on a regular basis.

Use a scriber or fingernail polish to mark mechanical zero on the front and rear sights ( front sight base flush with front sight post housing. Rear sight at 8/3 or 6/3 ( see zeroing methods on this site ). Each shooter using the same weapon should sight the weapon in, then count how many clicks the front and rear sight are from mechanical zero. Log this in your book. When you check out the weapon. Return the sights back to mechanical zero , then move the correct number of clicks to set to your zero. Although you sight the weapon in at 25 to 50 yds, shoot the weapon from 3 to 100 yds( or more if you can. At close range, the weapon will shoot low ( mine shoots 3" low at 3 yds and 2" at 7 yds. )

Weapons are issued to individual officers, and zeroed to their tastes. Standard is 100-yard zero with offset aim for CQB, but we leave it up to the shooter to make their own individual adjustments.

As long as they can qualify at CQB and intermediate distances, and perform the standards drill, we figure they have demonstrated proficiency and know what they are doing. Passing for our qual course for rifles is 90% with 5 CQB headshots (must hit 3 X 5" target area) and sucessful completion of all standards on the standards drill.
