Born from a long line of high performance riflescopes, the VX-3 builds on everything we’ve learned in our 100-plus years of experience. Designed, machined, assembled, and tested by true optics craftsmen who take as much pride in a job well done, as you will in the field. >>QUANTUM OPTICAL SYSTEM >>VX-3 riflescopes feature the Leupold Quantum Optical System. Carefully selected and ground lead-free lenses, featuring Xtended Twilight coatings, are precisely positioned in optimum relationship to each other to produce the highest level of light transmission and optical clarity. >>DIAMONDCOAT 2 SCRATCH RESISTANCE >>All exterior lens surfaces feature our exclusive DiamondCoat 2 ion-assisted coating to provide superior resistance to scratching and abrasion. Exceeds military standards for hardness and durability, and aids in light transmission. >>SECOND GENERATION WATER PROOFING >>Leupold was first to employ bone-dry nitrogen to keep scopes free from moisture and fogging. Now we add a unique Argon/Krypton gas blend that resists thermal shock and reduces the diffusion of internal gases over time. You get absolute waterproof integrity – guaranteed. >>BLACKENED LENS EDGES >>Reduces unwanted glare and diffusion through the lens edges to provide better resolution, improved contrast, and superior optical performance. >>ONE PEICE MAINTUBE CONSTRUCTION >>Machined from 6061-T6 aircraft-grade aluminum for the utmost in structural integrity. Side focus and illuminated scopes feature a larger 30mm maintube. >>LOCKABLE, FAST FOCUS EYEPIECE >>Helps you get on target faster. Locks up tight to prevent movement under recoil. Includes a removable Alumina rubber eyepiece guard. >> TWIN BIAS SPRING ERECTOR SYSTEM >>Exerts up to 30% more holding force on the erector, virtually eliminating backlash and stress on the internal workings of the scope. You get a lifetime of rugged reliability.
