| I sighted in my M! and want to zero out the elevation knob. It is sighted in at 100 yd. Is the hash just below the "200" the "100" yd mark? I wasn't sure and just aligned the index to the "200" Is this correct? |

If you zeroed at 100 then the knob needs set at 100
I actually dont bother with setting the knob, it can come loose at the worst possible moment then yo will have to zero all ver again Better option is to zero at 100, 200 etc. Count the clicks from qwhere you are zeroed to the sight all the way down. Right this info on a piece of paper and put it in the trap door in the stock. This way if you ever loose your zero all you have to do is count up clicks to get back on target |
| click counting also prevents you from wearing out just one spot of the elevation serrations on the reciever. Every so often you just move the sight knob when you reinstall after regreasing. At least that's what the match shooters used to do instead of setting to the numbers. |

The starting point for windage zeroing your M1 or M14 is to get a "no-wind" windage zero. Center your rear sight according to the index marks on the receiver and sight base. Center the front sight in its dovetail (loosen the Allen-head screw, of course) as best you can by eye. Using a pencil, draw a witness mark on the sight & base. Fire a group at 100 yards (under "no wind" conditions, of course!). If your group is not centered, loosen the front sight and move it opposite to the direction you want the group to move. Continue to fire and adjust until your group is centered. You may, of course, have to put a click or three on the windage if your front sight starts to overhang the sight base. If you find that your front sight is "way too far" over, you may have a bent barrel or other problem; consult with Clint. For elevation, start with eight clicks up from the bottom at 100 yards. Each click (either windage or elevation) with standard sights is 1 MOA, so one click will move you one inch. Typically you'll come *down* one click at 200 yards. If you can, confirm your zero at 200 yards; this will allow you to loosen the screw in the elevation knob and turn the knob so that the "2" mark is opposite the index on the sight base. A quick & dirty "battle zero" may be obtained by zeroing 1.25 in up from the point of aim (for .30-'06) at 25 yards. This zero should allow its on man-sized targets form 0 to 400 yards. My red added.

| Thanks for the replies. Once I loosened the set screw I had a hell of a time pulling back on the elevation knob to align it because it was so tight. Even with the screw ready to fall out, pulling out as hard as I can, when I rotated the knob it would move the sight. I think i like the idea of counting the clicks from the bottom for my 100 yd zero. It was 10. |
