Has anybody mounted an optic on the dovetail of their M&P22 Compact? I've seen some on the regular M&P22 but not the compact. Would like to mount something small like an RMR or something cheaper but the same size/weight. I don't know if it's possible for it to cycle properly (mine will be suppressed) and if there is an easy dovetail mod that will make it easy to mount? I love this gun and would love to mount a sight to it, but if it's not easy/cheap I may have to pick up a Ruger 22/45 that has a rail on top.
