I set up my Mini with an Aimpoint CompM3 in a single Ruger 30mm ring.
Yea, I've looked at a few single-ring setups, including one using a Primary Arms red dot sight that looked pretty slick. I couldn't talk myself into just one anchor point for my sight, though, and I don't know much about Primary Arms' product yet. I guess all of my "triple anchor point" marketing talk for the Mo-Rod has me brainwashed. For this new application I'm working on for a 581-series Ranch Mini, I have to leave myself an easy option for transitioning to the use of my Mo-Reaper front sight. But, I've also become pretty addicted to the world of red dot sights. Anyway, I'll share it as soon as it comes together...
