The official Army zeroing procedure (http://www.armystudyguide.com/content/army_board_study_guide_topics/m16a2/zero-and-m16a2-rifle.shtml) seems straight forward enough, but my problem is I don’t know how I’m going to do it based on what I’ve experienced so far. They tell you to
1) Front sight flush with top of sight post.
2) Rear sight elevation one click beyond the 8/3 position (rear sight elevation has an 8/3 position on the dial and then (with intermediate clicks), rotates one full revolution through 4, 5, 6, 7 and then back to 8/3. Total range 300-800yds). So, I guess the “one click beyond” the 8/3 is lower and used just for zeroing.
3) Rear sight windage zero.
4) Distance 25 Meters.
Note: After setting the rear sight elevation to that one click beyond the 8/3 position, all elevation zeroing is done with the front sight post. After that, the front sight post is never changed again.
My problem is that up to now, when at the NRA HQ Range shooting 150ft and 1), 2) and 3) applied, I’ve had to aim way low already. I can't imagine that I could have raised the front sight enough to lower the strike of the bullet to the point I could have aimed at center mass. Maybe it will be different at only 25 Meters (approx 75 Ft)? I don’t want to put my long front sight post on… but may have to in order to both zero it and shoot from 200-600 yds. You can’t really raise the front sight post very many click from zero.
I will be shooting "Across the Course" this weekend from 200, 300 and 600 yds.
My questions to the forum are 1) Have you had to use a long front sight post to zero your A2 AR at 25 meters and 2) Do you shoot from 200-600 yds with your AR and, if so, do you use a long front sight post?
