Vortex Optics Diamondback 4-12x 40mm Rifle Scope

Vortex Diamondback 4-12x 40mm Rifle Scope - 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. Dead-Hold BDC (MOA) Customized dot design helps eliminate guesswork on holdover and windage corrections. Good for hunting/shooting at varying ranges where estimating holdover is a concern. 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. 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.
