I just got off the phone Badger Ordnance about this same item not but 5 minutes ago. I was inquiring about the fit of the rings if I am using a scope with a 50 mm objective and a 20 MOA base. Unfortunately with a straight taper barrel, you will need medium height rings. The Max 50's are either standard at .823 or high at 1.125. The Max 50's don't come in a medium height of .885. I don't need the Max 50's but they look good. So no Max 50 rings for me!
I appologize, they may work for you, however with my barrel contour I'll be using 1.25 to either .910 or .830, they will not work.
