The Crossfire is a no-nonsense sight at a no-nonsense price for darn near any application, and when your AR-15, 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.
