Would feel a bit top heavy I believe. I initially mounted a VX6 3-18x44 to mine, but downsized to the 2-12x42 for that reason.

With a gun that light, I prefer a lighter optic. Will feel more stable in your hand.

Going from the top end of 9 to 20 is a bit extreme dont you think? Where will you be hunting this thing that you will need 20 power?
