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.
