As with most 3D targets, the body encases the core. Since the core includes the vital rings, it is where most arrows are aimed and shot. The body takes the brunt of the shots that miss the core, therefore, it can show wear and tear after prolonged, repetitive use. If the body on your Antelope 3D Archery Target (Part #50110) is no longer able to hold the core, or able to contain any additional arrow hits, replace it with the Antelope 3D Archery Target Replacement Body. The replacement body comes equipped with a new core, so you can get a new body and core in one easy purchase. Made from solid foam, the replacement body is the perfect way to stabilize your target for continued use.
