I recently put a 20moa base on my rifle with a leupold mk4 3.5-9 x 40 with m3 knobs that are in inch moa and now I don't have enough elevation to go Down far enough to obtain a 100 yard zero are they a way to return to factory zeroed out since this was sighted on on a 0moa base ?
 
loosen set screws on knob. while up against the zero stop.
turn knob up 10 moa. tighten set screws.
punch yourself in the dick
now you can adjust father down

there is a little nub on the knob that is your zero stop. i alway take my allen wrench when i go to zero my mark 4 incase i have to go below the zero on the knob to sight in.
