I mounted this scope on a savage mark 2 tr 22.long rifle. The turrets are easy to work with and firmly lock in place. The turrets are well marked and easy to return to zero. The blue illumination is very nice and in the evening doesnt wash out the target. The bubble in the bottom is small and not worth much in my opinion.The paralax adjustment is stiff, it works well but it is stiff. It comes with dust covers but they are not of the caliber of butler creek. I feel like this glass is worth the money.
