reseting the rear sight?

[espi]

Ok,
Now that the rear sight is good to go, how do I reset the "knob" to "M" for my 1st zero at 100 yrds? It has something to do with the semi circle spring.
ANY help would be appreciated.

Thanks,
Espi

You should just have to loosen the screw on the right side knob. that should allow the left knob to move freely without moving the sight. When you get it where you want it - re tighten....:usa:
