EBR-4 (MOA)

Hash-marked ranging reticle using MOA or MRAD based subtension lines for ranging, holdover, and windage corrections. Letters refer to reticle subtensions listed in chart below.

Included in the Box:

CR2032 battery
Lens cloth
2 mm hex wrench
3" sunshade

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.
Glass-Etched Reticle
Allows for intricate reticle design. Protected between two layers of glass for optimum durability and reliability.
Illuminated Reticle
Provides precise aiming under low-light conditions

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 aluminum 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.
Tactical-Style Turrets
Exposed turrets provide fast, accurate and easily read elevation and windage adjustments.

INTERNAL MECHANISM DESIGN FEATURES

RZR™ Zero Stop
Rapid Zero Return (RZR) feature stops the turret from dialing below sight in range using rugged steel components. Internal mechanisms stay free of sand, dirt, dust, moisture and other foreign materials - even when setting the zero-stop position.
Precision-Force Spring
System Uses premium components in the erector-spring system to ensure maximum repeatability and ease of adjustment.
Precision-Glide Erector System
This system ensures the components in the zoom lens mechanism glide smoothly and cleanly through all magnification ranges.

CONVENIENCE FEATURES

Radius Bar
Fiber optic turret rotation indicator provides a highly visible and tactile point of reference for turret rotations.
Fast Focus Eyepiece
Allows quick and easy reticle focusing.
Built-In Accuracy Features
Matching (MRAD or MOA) turrets and reticles facilitate fast and accurate shooting at extended ranges. The patented fiber optic Radius Bar visually assists tracking turret rotations.
