leverman, I have two Matchdot II optics; one is on a Ruger Mark III, the other is fitted on a Ruger Super Blackhawk Hunter in .44 Mag. I like the options given from 2 MOA to 8 MOA with choices of reticle patterns. I've yet to have a problem with either. One is used on squirrels while the other deer and such. I'm getting ready to explore their new Micro HD model. From my experience, the Ultra Dots have performed flawless.
