Features | Benefits |
|
|
| 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. |
|
|
| XTENDED TWILIGHT: | As part of the Quantum Optical System, this feature takes all Leupold's knowledge, expertise, and experience with light transmission and moves it one step closer to perfection, matching the proper balance of lens coatings with specifically engineered glass and index of refraction. The result allows you to reach deeper into twilight and low-light settings, helping you to better distinguish antlers from branches and animal hide from brush. |
|
|
| DIAMONDCOAT 2 SCRATCH RESISTANCE: | All exterior lens surfaces of the VX-3 6.5-20x40mm EFR scopes provide superior resistance to scratching and abrasion. Exceeds military standards for hardness and durability, and aids in light transmission. |
|
|
| SECOND GENERATION WATERPROOFING: | Bone-dry nitrogen coupled with a unique Argon/Krypton gas blend that resists thermal shock and reduces the diffusion of internal gases over time. You get absolute waterproof integrity in every VX-3 6.5-20x40mm EFR Target Scope—guaranteed. |
|
|
| 1/4-MOA FINGERCLICK ADJUSTMENTS: | Tactile, audible clicks provide precise windage and elevation adjustment. Adjustment screws are cryogenically treated for increased durability and precision. |
|
|
| BLACKENED LENS EDGES: | Reduces unwanted glare and diffusion through the lens edges to provide better resolution, improved contrast, and superior optical performance. |
|
|
| LOCKABLE, FAST-FOCUS EYEPIECE: | Helps you get on target faster. Locks up tight to prevent movement under recoil. Every VX-3 6.5-20x40mm EFR Target Scope 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. |
|
|
| TACTILE POWER INDICATOR: | Features built-in range estimation functions and graphite O-rings for easy operation. |
|
|
| ONE-PIECE MAINTUBE CONSTRUCTION: | Machined from single billet 6061-T6 aircraft-grade aluminum for the utmost in structural integrity. |
|
|
| SCOPE COVER: | VX-3 6.5-20x40mm Extended Focal Range scopes include a full neoprene scope coat for extra protection during transport or when not in use. |
