Diamondback 3-9x40 With V-Plex Reticle by VORTEX OPTICS The Diamondback—loaded with features! First and the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fogproof performance on the agenda and and advanced fully multi-coated optics raise an eyebrow when crystal clear and tack-sharp images appear in the crosshairs. Look for all this and more in a riflescope you'd expect to cost quite a bit more-but doesn't. We can live with that. Optical Features Fully Multi-Coated - Increases light transmission with multiple anti-reflective coatings on all air-to-glass surfaces. Second Focal Plane Reticle - Scale of reticle maintains the same ideally-sized appearance. Listed reticle subtensions used for estimating range and holdover and wind drift correction are accurate at the highest magnification. Construction Features Tube Size: 1-inch diameter. Single-Piece Tube - Maximizes alignment for improved accuracy and optimum visual performance and as well as ensures strength and waterproofness. Aircraft-Grade Aluminum - Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
