Vortex Diamondback 4-12×40 Riflescope with Dead-Hold BDC Reticle (MOA)

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.

4-12×40 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 any hunting or shooting at varying ranges where estimating hold-over would be a concern.
