Shooting gongs are manufactured from new high quality 3/8 inch thick AR500 hardened steel plate made in the USA. These AR500 targets are rated to 3200 fps at 100 yards. Gongs are painted white on all sides with high quality paint. Gongs are ready to use right out of the box No Painting! No Mess! No Waiting! Gongs are painted white to provide the maximum contrast between the sights/crosshairs and the target, as well as the background. This contrast gives you the Fastest and Easiest Target Acquisition. Gongs are precision cut with a CNC plasma cutter and submersion water cooled during the cutting process to maintain the integrity of the metal, ensuring the longest life of the target. Reversible steel target face doubles the life of the shooting target. Gongs can be hung from hardened chains, using bolts or clevises. Tarp straps and rope can also be used for hanging gongs.
