EBR-4 (MOA) Reticle | 30mm Tube
The Viper PST Gen II hands an unfair advantage to shooters who seek to keep the upper hand in every situation from close quarters to long-range shots. The illumination dial is cleanly integrated into the side focus adjustment knob for easy access and streamlined performance. The glass-etched reticle offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing and features 10 intensity levels with off positions between each setting.

| 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 |
| First Focal Plane Reticle | Scale of reticle remains in proportion to the zoomed image. Constant subtensions allow accurate holdover and ranging at all magnifications. |
| 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 |
| 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. |
| 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. |
| 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. |
EBR-4 (MOA)
