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.
