These AR 500 Steel Alloy Gongs are a no frills gong for guys that shoot a lot. They are unpainted, super tough, and have a great ring when hit. We have set them up with two holes on the upper corners for swinging on chains and have also placed a diamond cutout in the top center for carriage bolting to a post. Great price and value. These targets can stand thousands of shots when rotated periodically to wear both sides of the plate evenly.
