Features of Vortex Venom Red Dot Sight w/10 Brightness Levels:

• Fully Multi-Coated. Multiple anti-reflective coatings on all air-to-glass surfaces increase light transmission.
• Premium Wide-Field Lens. Exceptional edge-to-edge resolution.
• Brightness Settings. Choose between 10 levels of brightness in manual mode or switch to auto mode.
• Parallax Free. All red dot and holographic sights will exhibit some small amount of parallax. Matching current industry practice, this small amount would be considered parallax free and will make a negligible difference in performance.
• Single-Piece Chassis. Compact and lightweight.
• Waterproof. O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.
• Shockproof. Rugged construction withstands recoil and impact.
• Hard Anodized Finish. Highly durable low-glare matte finish.
• ArmorTek. Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.
• Unlimited Eye Relief. Non-critical eye relief for rapid target acquisition.
• Top-load battery for easy replacement without needing to remove the sight.
• Battery Life. 14-hour auto-shutdown feature maximizes battery life. Up to 150 hours of use at highest setting. Use at the more common lower settings can allow up to 30,000 hours.
