    just google "combat zero" and try that, thats how we were taught on M16 40 years ago and most AR, M14 manuals recommend this too.

    I sight it in at 100 yards for an AR as a civilian because if I'm using an AR, I want to know exactly where my bullets go at various distances. The distance between your bore centerline and optics centerline will shrink until it's zeroed at 100 yards (or meters) and the bullet drops from that point on. What is your purpose?

    Do you plan to engage targets from 0-300 meters and don't want to take into account bullet drop and all you're concerned about is landing hits on an enemy combatant's torso within a 12" vertical variation? It's easy for the military to do this because they can't just crank out a 100m berm in the field. Doing things at 25m is pretty simple to construct.

    With a 25/300m zero, you're about 6" high at 100m before it drops again and crosses at 300m. You're shooting low, then high, then low again and you have to keep track of it if your shots have to be precisely placed.

    Battle sight zero is the term you're probably after. There is also the Improved Battle Sight zero as proposed by Ltc. Santos. There are several other methods, with one of the most popular being a 50 yd zero. This will keep you +/- 2.5" from muzzle contact to a little over 200 yds.

    Do you have a particular application you plan to use this rifle for?

    Jenrick, like I said for me it was 41 years ago...times, terminology change, whatever, this old grunt can still sight in his ARs using this method.

    I'm not in the army, nor do I anticipate shooting at man-sized targets out to 300 yards...so I use a 50 yard zero for home or perimeter defense. It's on target with 6-inch plates at 200 yards.
