Vortex CF-RD2, Crossfire Red Dot LED. The Crossfire is a no-nonsense sight at a no-nonsense price for darn near any application, and when your shotgun or rimfire needs a simple point of aim and none of the frills, the Crossfire should be at the top of your list.The 2 MOA dot is quick to acquire in close-quarters, while remaining fine enough to promote pin-point accuracy at extended range. With a 50,000 hour battery life and night-vision compatibility at the lowest two settings, the Crossfire red dot will keep working in a variety of conditions. In addition to just plain looking awesome, the included skeletonized lower 1/3 co-witness mount provides a rock-solid and extremely lightweight platform. Battery Life: Up to 50,000 hours on brightness setting 6. Fully Multi-Coated Increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces. Unlimited Eye Relief Non-critical eye relief for rapid target acquisition. 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.
Night-Vision Compatibility The lowest 2 settings are night-vision compatible. Waterproof O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments. Hard Anodized Finish Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position. Max Elevation Adjustment 100 MOA. Max Windage Adjustment 100 MOA.
