XD™ Lens Elements
Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
XR™ Fully Multi-Coated
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.
Tube Size
30 mm diameter provides maximized internal adjustment and strength.
Single-Piece Tube
Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
Aircraft-Grade Aluminium
Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
Waterproof
O-ring seals prevent moisture, dust and debris from penetrating 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 Black Finish
Highly durable Type III hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position.
ArmorTek ®
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.
Side Focus
Adjustment located on left side of turret housing is easily accessible from shooting position. Provides optimal image focus and parallax removal.
Precision-Force Spring System
Uses premium components in the erector-spring system to ensure maximum repeatability and ease of adjustment.
Precision-Glide Erector System
This system ensures the components in the zoom lens mechanism glide smoothly and cleanly through all magnification ranges.
MAG-Bar
Allows rapid, easy changes in magnification.
Fast Focus Eyepiece
Allows quick and easy reticle focusing.


Dead-Hold BDC (MOA)
The customized design of this reticle helps eliminate guesswork on hold-over and windage corrections. Good for hunting and shooting at varying ranges where estimating hold-over is a concern.
