Leupold Mark 4HD 4.5-18x52 Rifle Scope Unboxing

BigJimFish‬ The Leupold Mark 4HD 4.5-18x52 arrived for it's upcoming review. I unbox it, talk a little about my experiences with the Mark 5HD I reviewed a few years ago, the changes between the Mark 5HD line and the Mark 4HD line, and what I am most interested in testing on the Mark 4HD.
