Designed as a multi-purpose, utilitarian mid to long-range optic, the Hawke Optics 3-9x40 Vantage Riflescope boasts a 40mm objective that draws in generous amounts of light versus smaller objectives while helping to maintain a low-profile to reduce snags and weight. Covered turrets help guard against accidental adjustments while a fast-focus collar and zoom ring allow you to quickly adapt to rapidly changing situations. Complementing the performance of the scope is a lightweight and durable anodized aluminum housing, with a 1" one-piece maintube that is nitrogen-filled and O-ring sealed to be water and fogproof.
