Hello, I ordered the Leupold Dual Dovetail with Med Rings and it could not have been any lower (objective is about 1/8" off bbl). I removed the open sights as with this system, you could not remove the scope to access them anyway. The hammer clearance is very tight, I am glad this model has the swing hammer. This is the absolute lowest I would go with Leupold DD system and would have ordered low rings had it not been for the suggestions of the helpful members of this site. If you look at Leupolds site and go to their mount selector, they actually recommended low rings- I do not think this would have worked. Thanks everyone for your input. In the near future, we will be going to the range with 110 gr Blackhorn and some SW Bonded 250s- I will let you know.
