Try out our Sniper Training Cubes. In case you haven't seen them, they are a 4"x4" Ballistic Polymer Cube. When you hit one, they will jump in a very unpredictible way. Every time the Cube lands, you will have a 4" surface to shoot at. Even while shooting by yourself they are a blast. If you have a buddy or two shooting with you, try Cube Racing.... Try to shoot your Cube across a predetermined finish line before the others. They come in multiple colors, which helps to keep them straight.
The Sniper Training Cube is for rifle caliber only, so if you are using pistol calibers, be sure to check out the Pistol Cube.
If you go to the homepage, you will see the Cubes.
