Has anyone had experience zeroing in this sight (Matech BUIS) with the fold down front sight that is on the 6940? Would anyone know where to find the manufactures instructions for it?

When zeroing, is the rear sight set at 300m or the line under it, and then use a 25m target @ 25m? After zeroing is figured out and set, are the rest of the settings (400,450,500,550,600) used as BDC/bullet drop compensating at that point?

There is not a front sight adjustment tool that comes with it, so pushing down the detent pin and turning the post at the same time is impossible with my fat fingers. Any tricks for this? Which way is "Up" CW or CCW because there is nothing that shows the difference between up or down? I am assuming CCW???

Thanks for any info.
