Hawke's Interchangeable Turrets for the Sidewinder ED gives you the freedom to customize your windage and elevation adjustments to fit your style, personal preferences, or goals. This pair of precision turrets offers finger-operated adjustments without the need to carry extra tools or to perform complicated procedures. Simply unscrew its locking collar and lift a turret barrel off the scope and then reverse this process with a different turret. Moreover, your Sidewinder ED's hermetic design will keep the scope tightly sealed from dust, moisture, or elements even without the turrets. To provide precise and secure adjustments in the most challenging conditions, these turrets also feature well-defined graduation and a locking mechanism.
