Vortex Diamondback 4-12x40 BDC Scope

The Diamondback is loaded with features!
First, the solid one piece aircraft grade aluminium alloy construction makes the Diamondback riflescope virtually indestructible; it is highly resistant to magnum recoil.
Argon purging puts waterproof and fogproof performance on the agenda, and advanced fully multi-coated optics raise the stakes when crystal clear, tack sharp images appear in the crosshairs.
Look for all this and more in a riflescope that you would expect to cost quite a bit more, but doesn't. We can live with that!

4-12x40 riflescope is ideal for big game, predator/varmint, muzzleloader, slug shotgun, and long range applications.

Dead-Hold BDC Reticle (MOA)
Customized hash mark design helps eliminate guesswork on hold over and windage corrections. Good for hunting/shooting at varying ranges where estimating hold over is a concern.

OPTICAL
Fully Multi-Coated Lenses - Increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.

CONSTRUCTION
One Inch Tube - Standard tube diameter for most American riflescopes.
One Piece Tube - Maximizes alignment for improved accuracy and optimum visual performance as well as strength and water resistance.
Aircraft Grade Aluminium - Premium grade of aluminium, valued for fatigue resistance.
Precision Glide Erector System - Uses premium components in the zoom lens mechanism, ensuring smooth magnification changes under the harshest conditions.
Fast Focus Eyepiece - Allows quick and easy reticle focusing.
Low Profile Turrets - Less susceptible to accidental impact damage.
Reset Turrets - Allow re-indexing of the turret housing to zero after sighting in the riflescope; generally requires use of a coin or wrench.
Waterproof - O-ring seals prevent moisture, dust, and debris from getting inside the tube, ensuring reliable performance in all environments.
Fogproof - Filled with argon gas to inhibit internal fogging.
