EBR-4 RETICLE (MOA)
Hash-marked ranging reticle using MOA based subtension lines for ranging, holdover, and windage corrections.
XD™ Lens Elements
Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
XR Fully Multi-Coated Lenses
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 40x magnification.
Protected between two layers of glass for optimum durability and reliability.
Provides precise aiming under low-light conditions.
30mm Tube Size
30mm diameter provides maximized internal adjustment and strength while maintaining light weight.
Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
Premium grade of aluminum, valued for fatigue resistance.
Waterproof, Fogproof and Shockproof
O-ring seals prevent moisture, dust, and debris from getting inside the tube for reliable performance in all environments. The scope is filled with nitrogen gas to inhibit internal fogging. Lenses are locked in place, fore and aft, with machined locking rings to remain in perfect alignment and withstand recoil and impact.
Hard Anodized Finish
Hard-coat anodization is durable; the low-glare matte helps camouflage the shooter's position.
Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.
Exposed turrets provide fast, accurate and easily read elevation and windage adjustments.
RZR Zero Stop
Zero Stop mechanism prevents the turret from dialing below sight-in range.
Precision-Force Spring System
Uses premium components in the erector-spring system, ensuring maximum repeatability and ease of adjustment.
Precision-Glide Erector System
Uses premium components in the zoom lens mechanism, ensuring smooth magnification changes under the harshest conditions.
