So, my question is about leveling a scope on your gun. The gun in question is not a "precision bolt action gun" nor is it a "18 or 20 inch SPR." What I am about to ask I have always wondered. The gun I had the Scope Leveled on installment, you bring the gun (AR15 14.5") up to shoot off-hand (scope 1-4x24) the crosshairs are a little canted. I have another gun that I leveled via (eyeball method) where I picked up the gun a dozen or so times and tightened down the mount when it looked level (to me). So, when I pick that gun up to shoot off hand the crosshairs look level. I never checked to see if the eyeball method was level, maybe I will later today. Zeroed at 25 yards. I shoot more off-hand than any other way. How do you mount your scopes? Do you use a level? Thanks for any feedback!
