The VX-6HD is begging to go where other scopes can't. We gave it new High-Definition lenses for sharpened clarity, and the Twilight Max Light Management System for even greater low-light performance, giving 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 40 MOA (80cm), if necessary. All Leupold VX-HD riflescopes are CDS capable and include one free Custom Ballistic Dial with purchase. To take it totally over the top, we added an in-scope cant indicator for precise leveling, a throw lever for fast magnification changes, and an even more robust erector system.
