I'm also scoping out compact lightweight optics for my new project
A Mt Goat and Dall Sheep hunting rifle that will also work as a rough terrain hiking moose and black bear hunting rifle
Weight was a key factor coupled with good quality in something around a high power end at minimum of 10x and max bell diameter of 42mm, no large protruding turret/target knobs but rather short sleek hunting type
so far I have several on my list and currently at the top are ....
Swarovski Z3 3-10x42 at 12.7 oz. and 12.64" long
Swarovski 3-10x42 Z3 Riflescope
Zeiss Terra 4-12x42 14.8 oz and 12.4" long
