Vortex Diamondback 4-12x40 Dead-Hold BDC Scope

Diamondback riflescopes are 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.

Optical

• Fully Multi-Coated: Multiple anti-reflective coatings on all air-to-glass surfaces for increased light transmission.
• Second Focal Plane Reticle: Reticle maintains consistent appearance at all magnifications. Subtensions for range estimation, holdover, and wind drift are accurate at highest magnification.

Construction

• Tube Size: 1" diameter.
• Single-Piece Tube: Maximizes alignment for improved accuracy and visual performance, ensuring strength and waterproofness.
• Aircraft-Grade Aluminum: Constructed from a solid block for strength and rigidity.
• Waterproof: O-ring seals keep out moisture, dust, and debris in all environments.
• Fogproof: Argon gas purging prevents internal fogging across a wide temperature range.
• Shockproof: Rugged construction withstands recoil and impact.
• Hard Anodized Finish: Low-glare matte finish for durability and camouflage.
• Capped Reset Turrets: Re-indexable to zero after sighting in, with caps for external protection.

Internal Mechanism

• Precision-Glide Erector System: Premium zoom lens components for smooth magnification changes under harsh conditions.

Convenience

• Fast Focus Eyepiece: Quick and easy reticle focusing.
