Vortex Diamondback 3-9×40 BDC

The Diamondback is loaded with features. The solid, one-piece aluminum alloy construction makes the Diamondback riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging makes the scope waterproof and fogproof, and advanced fully multi-coated optics allow crystal clear, tack-sharp images to appear in the crosshairs. All this and more in a riflescope at a modest price.

• 3-9×40 riflescope is ideal for big game, predator/varmint, muzzleloader, slug shotgun, and long range applications.
• Dead-Hold BDC reticle has a customized design that helps eliminate guesswork on hold-over and windage corrections. Good for hunting or shooting at varying ranges where estimating hold-over would be a concern.
