Vortex Diamondback 4-12x40mm BDC #DBK-04-BDC
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.
Fully Multi-Coated - Proprietary coatings increase 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.
Tube Size - 1 inch diameter tube offers a versatile blend of adjustment, size and weight for a wide variety of shooting applications.
Single-Piece Tube - Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
Aircraft-Grade Aluminum - Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
Waterproof - O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.
Fogproof - Argon gas purging prevents internal fogging over a wide range of temperatures.
Shockproof - Rugged construction withstands recoil and impact.
Hard Anodized Finish - Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position.
Capped Reset Turrets - Allow quick re-indexing of the turret (no tool needed) to zero after sighting in the riflescope. Caps provide external protection for turret.
Precision-Glide Erector System - This system ensures the components in the zoom lens mechanism glide smoothly and cleanly through all magnification ranges.
Fast Focus Eyepiece - Allows quick and easy reticle focusing.
