M14 --- how to battle sight one?

[no4mk1t]

As a Service Rifle competitive shooter that shot the M14 for many years, consider reduced distance zeroing good enough to get you "on paper", but there is no substitute for zeroing at the actual distance desired. You want to obtain your hard zero at no less than 200 yards/meters.

To make the elevation knob graduations correspond, get a good zero at 200 yards/meters.
Record the number of clicks up from bottom.
Bottom the sight.
Loosen the center screw on the elevation knob.
Rotate the elevation knob downward to align the witness mark on the receiver with the 200 meter mark.
Continue to rotate the elevation knob downward the number of clicks you wrote down as your 200 yd/meter zero.
Secure the elevation knob center screw.
Elevation zero is now complete.

Windage zero.
Determine your no wind zero at no less than 200 yds/meters.
Once you have your no wind zero established. Mask the sight base to receiver, and windage knob to receiver and paint marks as shown in the pic.
This makes it possible to return to your windage zero exactly every time.

Be advised that the elevation graduations are calibrated for M80 Ball. Out past 300 yds. if exact zero data is required, best keep a data book with elevation settings for that particular load.
