Barska's Air Gun Scopes are the perfect optics for your CO2, pump, or break-barrel air gun. This rifle scope features a 30/30 reticle for quick easy targeting. An Adjustable Objective Lens (AO) allows the user to focus in on the target and adjust the settings to coincide with the distance to the target in yards. Fully coated optics come standard with this series, and provides a bright, clear image with less eyestrain to the user. Barska's Airgun Scope Series is ideal for competitive and recreational air gun shooting.
