I have the same rangefinder. Never weighed it though. I have a Leupold 6.5-20x50 on my 22-250 Awsome optics. Again get what you pay for. I dont take my rangefinder backpacking as the magnafication is a bit weak compaired to my binocs. I use rangefinder for Coyote hunting. I just ordered a Nikon scop for my Ar. I have read nothing but good reveiws about them. I figure they make excellent cameras why not scopes?
