The Killzone is a 2-blade rear-deploying broadhead that packs a devastating 2" cutting diameter. The field-point accurate Killzone uses NAP's unique spring-clip design which ensures your blades won't open in flight or in your quiver. There are no O-rings or rubber bands to worry about. Fitted with a Trophy Tip for bone-crushing power. The Killzone comes in a package with three broadheads and one practice blade.
