    If you use the one thats in your FSB it'll probably require that to zero at 50yds your front sight post will be nearly falling out of the FSB.

    Also remember that moving the front sight up makes the group go down. This is opposite what the rear does where moving the rear sight left makes the group go left. When doing the 50yds zero the rear sight elevation is bottomed out like I said earlier 6/3 -4 clicks (4 clicks lower than it's lowest marked setting). The rear sight usually requires a 1/16" allen wrench to allow it to do this. During zeroing the only elevation changes are made at the front sight and windage is at the rear sight.

    This is complete directions for the Santose 50yd Zero.
    I second that. Zero the carbine with the rear sight set properly so you can set it to different ranges and still hit without using Kentucky windage.

    So I've got a question. My rifle is doing the same thing and when I tried to bottom out the rear sight, the 1/16" wrench wouldn't fit. And my front sight isn't F marked. I finally sighted it in at 30 yrds for minute of man, but my rear sight's at 4 clicks after 4.

    I have tried the 50 yard zero technique and that is why I don't understand why it shoots low with the standard FSB and the front post turned all the way down. It shoot be shooting very high. Can my rear sight be that far off? Is there a standard measurement for the a2 carry handle on the a3 receiver?

    I feel like a idiot now. I figured out my problem. Come to find out my front sight post had a lot more room to go down. So I finally have it shooting correct. I have one more question. My carry handle rear windage adjustment knob is labeled 1 thru 20. So do I just bottom it out at 0 and then zero the gun at 50y? And after zeroing it does it mean if I turn the windage adjustment to 5 = 500yards 10= 1000? Thanks for all your guy's help

    If it were me I'd just replace that who knows who's it is carry handle with either a Colt one (or better yet, a fixed rear sight like the LaRue BUIS) and install a taller .040" front sight post. You really don't need a 6-800yd rear sight on an AR15 (just my opinion).

    Bottom out the "windage" knob?

    Windage controls affect the horizontal position of the rear peep sight. The sight should be centered at the beginning of the zeroing process. Then the windage knob turned to move the point of impact left or right so that it coincides with the point of aim.

    Yes

    No, the numbers are equal to the number of 'clicks' not to any particular range. This kind of elevation wheel is more generic, like the elevation knobs on scopes.
