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.

Vortex Diamondback 4–12x40 Riflescope Dead-Hold BDC MOA Reticle

Vortex Diamondback riflescopes are considered to be one of the most popular hunting scopes. One-piece construction makes the Diamondback tough, recoil-resistant and improves alignment accuracy. Fog proofing and waterproofing allow this scope to be used under various weather conditions. Adjustable objective (AO) allows maximum precision on small targets. 4-12x40 riflescope is ideal for big game, predator/varmint, muzzleloader, slug shotgun, long range, and target applications.

Dead-Hold BDC MOA Reticle

Customized dot design helps eliminate guesswork on holdover and windage corrections. Good for hunting/shooting at varying ranges where estimating holdover is a concern.
