The VORTEX Diamondback 4-12x40 Riflescope, Dead-Hold BDC Reticle, Matte Black (DBK-04-BDC) is ideal for big game, predator/varmint, muzzleloader, slug shotgun, long range, and target applications.
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 91% of the light - delivering the bright details you need when taking aim.
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.
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.
The Dead-Hold BDC reticle has a customized design that helps eliminate guesswork on hold-over and windage corrections. It is good for any hunting or shooting at varying ranges where estimating hold-over would be a concern.
The Diamondback 4-12x40 Riflescope comes with removable lens covers, dust cloth and the VIP Unconditional Lifetime Warranty.
