Figured I'd pick the brains of those more familiar with the clip on scopes. I haven't had any luck getting consistent shifts from the daytime zero running a PVS-27 on a MARS rail. I figured there would be some shift when we got the systems, but there is not telling where it is going to shoot each time you remove and remount the PVS-27. The shift has been anywhere from .5-1.5 MOA in all different directions. Is that just something inherent with the clip on or does out mounting solution have something to do with the deviation. There is no shift running a thermal clip on, but it's about two pounds lighter than the 27. Is it too much weight for the MARS? Would the Badger EFR provide a more repeatable shift? I think the best option would be to have a dedicated night rifle, but I'm pretty sure the powers that be aren't going to spring for it. I appreciate any advice.
