The Target Factory Bottles allow you to take shooting practice up a notch. This patriotic 3-pack of Red, White & Blue bottles have been constructed from low-density polyethylene and can be used hundreds of times making them a great reusable alternative to glass bottles and are 100% recyclable. They are perfect for .22 plinking but for greater versatility, they are rated for all calibers. Target Factory Bottles can be placed on the ground or a fence for stationary targets, or you can use the included 6-foot rope to create hanging targets for an increased challenge.
