Just picked up a new Gen 2 S2K to play with. Took it to the range yesterday and went thru a box trying to get zeroed in. Initially she shot pretty low and to the left at 25yds but was able to get that pretty well corrected. I'm probably going to get a Bushnell TRS 25 but I'm at a loss as to what QD riser to get to attach to the RD and to the top picatinney (know this would need sanding) but I don't want a side mount. If I can, I would opt for a 1/3rd cowitness mount. Can you guys point me to a specific QD mount to solve my problem?
