Made from 3/8? thick Certified AR550 steel, these hanging gongs will withstand most high powered rifles. They?re ideal for both rifles and pistols and great for testing your skill. An audible ring and visual movements give immediate feedback to the shooter and promotes good shooting habits. We have designed them with two square mounting holes to hang on your choice of setup. These are CNC laser cut in order to maintain the integrity of the hardened steel. To lengthen the life of your target, RMP recommends a minimum shooting distance of 100 yards, with high powered rifles.
