I'm saving up for an S&B PM2 to put on a TRG 22. I'm trying to figure out if I want to go 5-25 or 12-50. I tend to like more mag, but I'm sure both will be fine. The question I have is related to options. The website is not very good at explaining what all the options are. It lists the elevation adjustment as 0,1 mrad and elevation at 0-22 mrad. So this means 1 click is 1cm at 100m. Now, the total adjustment is 220 cm at 100m (roughly 86 MOA?). Also, what does MTC mean?
