Vortex Diamondback Riflescope 4-12x40mm 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.

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.

CONSTRUCTION FEATURES:
+ Tube Size- 1-inch diameter.
+ 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 the riflescope 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 low-glare matte finish helps camouflage the shooter's position.
+ Precision-Glide Erector System- Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.
+ Capped Reset Turrets- Allow re-indexing of the turret to zero after sighting in the riflescope. Caps provide external protection for turret.
