Discover a riflescope with incredible performance features like premium fully multi-coated optics with 95 percent light transmission heavy duty Precision Force spring systems and the glass smooth Precision Glide erector system-delivering all this and more at a price that should have pulled a few more hundreds from your wallet than it did.

4-12x40 riflescope is ideal for big game long range predator/varmint and target 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.

Side knob parallax adjust allows quick and easy parallax adjustments with range numbers visible while in the shooting position.

Optical Features:
  • XD Lens Elements: Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
  • XR Fully Multi-coated optics: Proprietary coatings increase 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 tube offers a versatile blend of adjustment, size and weight for a wide variety of shooting applications.
  • 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 binocular 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 hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position.
  • Armor Tek: Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.
  • Capped Reset Turrets: Allow quick re-indexing of the turret (no tool needed) to zero after sighting in the riflescope. Caps provide external protection for turret.
