Looking for the one optic you need to max your AR's effectiveness in any environment? The SPARC AR features rugged construction that's still compact, with a lightweight form-factor. The 2 MOA dot is as easy as point and shoot - it's quick to acquire in close-quarters, but fine enough for pin-point accuracy at extended ranges. The SPARC AR has been updated from a 8,500 hour battery life to have a 50,000 hour battery life (at illumination 6), and also features night vision compatibility on the 2 lowest illumination settings. A unique, integrated base is hassle-free on any AR, or similar platform. For reliable performance and loads of user-friendly features, look no further. Features 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. Daylight Bright Red Dot - The daylight bright 2 MOA dot is fast and easy to use. Choose among ten variable illumination settings-the lowest two settings are night-vision compatible.
