Resetting zero stop on mk 6.

[OBR]

So, I bought my first tactical scope, and had no understanding what zero stop was, and decided to play with my zero stop before sighting in my rifle limiting my range of movement on the reticle. Basically, I want to start from scratch and set my scope up to original settings so I have equal amount of travel both ways. I noticed I have two revolutions on the zero stop. Yes, I can say that I'm the typical person that doesn't read instructions before doing anything.
