Vortex Diamondback 4-12x40 Riflescope Dead-Hold BDC Reticle DBK-04-BDC

Description

DIAMONDBACK 4-12X40 RIFLESCOPE
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.
4-12x40 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.
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, holdover and wind drift correction are accurate at the highest magnification.
