Vortex Diamondback 4-12x40 AO 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.

• 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.
• Adjustable objective (AO) allows maximum precision on small targets.

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.
• 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.
• Adjustable Objective: Adjustment for riflescope`s objective lens provides image focus and parallax removal.
• Fast Focus Eyepiece: Allows quick and easy reticle focusing.
