Caldwell AR500 Swinging Target is constructed using 3/8" rifle rated AR500 steel. The extremely durable cast urethane frame connectors provide a rigid frame yet allows bullets to pass through without damage.

The AR500 Swinging Target is highly portable for ease of use. 4 ground stakes are included to secure the target for large rifle impacts. Perfect for centerfire rifles and handguns, these targets are rated up to 3,000 fps impact velocity and 3,500 ft-lb impact energy.
