OPTICAL FEATURES
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.

CONSTRUCTION FEATURES
Tube Size	1-inch diameter.
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 riflescope 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.
Side Focus	Adjustment located on riflescope's left side and is easily accessible from shooting position. Provides optimal image focus and parallax removal.
