When your rifle, shotgun or rimfire just 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 scenarios, while remaining fine enough to promote pin-point accuracy at extended range. In addition to looking awesome, the included skeletonized lower 1/3 co-witness mount provides a rock-solid and extremely lightweight platform for your red dot. The Crossfire is a no-nonsense sight for near any application.
The daylight bright red dot is easy to see and paints targets regardless of lighting conditions or background.
The key thing to remember when shooting with the Crossfire Red Dot is to keep both of your eyes open! Shooting with both eyes open allows you to take full advantage of your peripheral vision to get on target very quickly. Eye placement is not critical.
The Crossfire Red Dot incorporates elevation and windage dials with audible clicks. Each small click will move the point-of-impact one Minute of Angle. 1 MOA will closely correspond to one inch at 100 yards, 1/2 inch at 50 yards, 1/4 inch at 25 yards, etc.
