Leupold built the VX-6HD to do what other scopes can?t. The advanced High-Definition optical system delivers sharpened clarity, and the Twilight Max? Light Management System gives unparalleled low-light performance, allowing hunters a visible advantage at dawn and dusk when the biggest game is on the move. The new CDS-ZL2 dial locks in place so it cannot be inadvertently rotated off its zero. A mere press of a button will allow the user to dial up elevation, up to 38 MOA (80cm), if necessary. All Leupold VX-HD riflescopes are CDS capable and include one free Custom Ballistic Dial with purchase. To push its capabilities further, we added an electronic reticle level for precise installation, a throw lever for fast magnification changes, and an even more robust erector system. 2nd Generation Argon/Krypton Waterproofing 30mm Maintube 6061-T6 Aircraft Quality Aluminum 6:1 Zoom Ratio CDS-ZL2 Zero Lock Adjustment with Revolution Indicator Electronic Reticle Level FireDot Illumination Generous Eyebox Guard-Ion Rain Shedding Coating MST (Motion Sensor Technology) Push Button Illumination Reversible Throw Lever Twilight Max Light Management System Twin Bias Spring Erector System Zero Lock Windage Adjustment ** BLEMISHED products may or may not include accessories.
