Something new from Leupold.
MRDS which fits into the existing dovetail, fits most regular holsters and is low enough to use the standard front sight and the optic body as BUIS.
Uses a 1632 battery accessible without dismounting the sight. Leupold claims 3.5 year battery life on setting 4 (is it 5 setting like the regular DPP ?)
Obviously this won’t work with hammer fired guns or SCDs and the window is gonna be like looking through a soda straw. One handed and unconventional positions are going to be an issue.
