About Vortex Optics 4-12x40 Rifle Scope

• The Diamondback loaded with features! First, 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 advanced fully multi-coated optics raise an eyebrow when crystal clear, 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.
• Experience great hunting in dense cover!! Vortex knows good hunting gets all the better with high quality optics. For that reason, Vortex makes sure every glass surface of the Diamondback is fully multi-coated to transmit a full 91 percent of the light delivering the bright details you need when taking aim.
• With a Diamondback riflescope on your firearm, you'll head out with complete confidence in the harshest of habitats. The Diamondback takes great strides against the abuse of repeated recoil with a rugged one piece main tube constructed of 6061 T6 aircraft-grade aluminum and sets high standards for waterproofing and fogproofing with argon gas purging.
• Precision-Glide Erector System features premium grade fluoropolymer teflon resin bushings that provide exceptional resistance to stress cracking, temperature change, corrosion, and friction-induced wear. In addition, these bushings have an ultra-low coefficient of friction for the smoothest possible operation of the magnification adjustment.
