Exposed turrets built for dialing elevation and windage allow wind drift compensation at extended ranges. When we say precise - we mean it. These turrets track better than any Bloodhound and reliably return to zero every time. A zero-reset feature lets you re-index the zero reference marks on both turrets after sight in, while fiber optic rotation indicators integrated into the turrets provide a visual cue of your turret’s position.
Key Features:

• XD Lens Elements. Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
• 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.
• Aircraft-Grade Aluminum. Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
• Precision-Glide Erector System. This system ensures the components in the zoom lens mechanism glide smoothly and cleanly through all magnification ranges.
• Exposed Turrets. Provide fast, accurate and easily read elevation and windage adjustments.
• Radius Bar. Fiber optic turret rotation indicator provides a highly visible and tactile point of reference for turret rotations.
• Magnification Rib. The raised rib on the magnification ring facilitates fast magnification changes in the heat of action.
• Waterproof. O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.
• Fogproof. Nitrogen 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 position.
