Diamondback 3.5-10x50 Dead-Hold BDC Reticle 

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.

Features

• 3.5-10x50 rifle scope 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.
• Optical
• 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.
• Fast Focus Eyepiece allows quick and easy reticle focusing.
• Construction
  • 1" diameter tube size.
  • Single-piece tube maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
  • Aircraft-grade aluminum is 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 rifle scope 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.
