Abstract
Rifle scopes with friction reducing elements include a scope body, a movable optical adjustment element connected to the scope body, and a turret rotatably connected to the scope body. The turret includes a contact element contacting the adjustment element at a location of contact. The contact element is rotatable with respect to the turret. The adjustment element at the location of contact differs in hardness from the hardness of a second portion of the adjustment element. The contact element at the location of contact and the adjustment element at the location of contact are of essentially equal hardness.
