That would make sense if the sights were co-witnessed.Wow.......I'm not rigid on most things, but I could NEVER ditch my rear sight.
The irons on my Mini are excellent sights and my last defense if something goes wrong with the more complex optic (whatever that may be).
I have my standard irons along with a 2x7 Burris with the original Ruger rings.
A riser is indeed needed because the stock is designed for the original standard sights--not a scope.
If your red dot goes down, you will have to stop and use a tool to remove it in order to see your irons correct?
Or would you run a QD mount which will raise your RDS another 1/4 an inch?
At that point I would rather rely on the etched reticle on a 1x power LPVO.
