    anyone know anything about LCol Santos improved battlesight zero for the AR 15? I tried the 25 meter zero for my M4 and I can't hit anything at 100 yards.

    I tried to follow the directions for the IBZ for my Bushmaster M4. It says to loosen the Allen screw on top of the carry handle three turns, leave the wrench in the screw, and click the sight clockwise. This should allow you to adjust the sight 2 clicks (4 half clicks for my M4) below the 6/3 mark.

    However, the screw rotates with the sight adjustment wheel and I am unable to retighten the screw once it rotates away from the hole at the top of the carry handle. I can't leave the wrench in the hole for the same reason- the wheel will not rotate with the wrench in place.

    Am I doing something wrong?

    Thanks

    Did you remove the allen wrench in when you turned the wheel?

    Play with it till you can get it back to where is was. Then leave the wrench in place when you make the adjustment.

    Been there...done that.

    That's my problem... the wheel wont turn if I leave the wrench in place. The hole for the screw appears to extend into the wheel, so the hole for the screw rotates away when I turn the wheel. Hope that makes sense.

    just tried it again... wheel wont turn when screw is backed out, with or without wrench in place.

    on the bright side, the wheel still bottoms out at 6/3, so I guess I haven't screwed anything up.

    Very confused:confused:

    Lovely, simple things, the original A1 sights...

    I wouldn't be surprised to see the military go back to them one of these days, particularly in view of the fact that so many M16s now wear optics anyway.

    www.ar15.com probably has detailed info on the A2 sights in a sticky.

    got it worked out!

    being an AR 15 newby and mechanically inept, did not realize that the elevation index wheel and the elevation knob were capable of rotating independantly when the screw is loosened. The "bottom part" of the elevation wheel is what needed to be rotated after the screw was loosened.

    Now I am at 6/3 -4 clicks and ready to sight at 50 yard for a 200 meter zero. Much more practical than a 300 meter zero!

    thanks to everyone who responded.

    It's easier the second time you do it.
