No other scope in its class comes even close to the quality, performance, and value of VX-1. With our revolutionary Quantum Optical System, with lead-free glass and Multicoat 4 lens coatings, the result is up to 92% total light transmission, and a sight picture that is incredibly bright, clear and razor sharp. Leupold's classic lockable eyepiece for a secure focus. All VX-1 scopes are oxygen purged and nitrogen filled for decades of waterproof and fog proof performance. Finger-adjustable dials (1/4-MOA per click) allow for quick and easy zeroing and adjustments in the field. Your VX-1 is covered for the life of the scope. The LR Duplex reticle is part of Leupold's exclusive Ballistics Aiming System and is available on select VX-1 models. For more information on the LR Duplex.
