Newbold's Knock-Down KD-Pivot Reactive Target and the Pivot Base it mounts on are each sold separately. When mounted on the Pivot Base and hit, this KD Pivot Target reacts and falls over backwards. It stays down until you reset it manually or by pulling on a string. Bullets pass through the KD target and the Pivot Base because they are both made of ElastiMAX™, our tough, flexible, self-sealing polymer. To mount a KD target on its Pivot Base, you simply snap it into place. Then secure the Pivot Base to your soft wood target stand with (4) wood screws or with (2) ElastiMAX™ Nuts & Bolts. For a different experience with the KD Series Targets, mount the KD Base upside down for swinging action and automatic reset or remove the target from the KD Base and hang from a wire.
