Adjustability

To make for a hassle-free experience, look for scopes with easy-to-adjust knobs. The windage and elevation turrets and knobs should be easy to turn and should also be the right size to provide faster target acquisition.

Eye Relief

This refers to the distance between the ocular from your eye so that you won’t get hurt during hunting or shooting.
