XD™ Lens Elements - Extra-low dispersion (XD) glass increases resolution and colour 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.

Construction Features

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 Aluminum - Constructed from a solid block of aircraft-grade aluminium 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 Finish - Highly durable 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.
