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.

3-9x40 riflescope is ideal for big game, muzzleloader, and slug shotgun 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.

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.

INTERNAL MECHANISM DESIGN FEATURES
Precision-Glide Erector System - Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.
