Robust construction with quality constructed components for fast adjustments. The fiber optic elements draws in natural light and focuses it to the sight dot. Designed to operate in low light conditions to maximize whatever light is available, you are assured with a bright sight marker to make target acquisition fast and easy. Windage, elevation, zoom, and brightness dials all offer a large grip surface, and are all placed in convenient positions. If you happen to own an airsoft rifle that can shoot far enough to make use of this, then this is the one you are after.
