The Knockout is part of a set that includes the Takedown and Charger, which are also available for purchase. The Knockout includes 2 Rival rounds and a set of instructions. A single shot blaster, this one is a hefty piece designed as a sidearm for large scale, if not professional, battles.
The Mercury (part of the Rival Edge series), is a bolt-action blaster that also includes a target and 5 rounds (as well as instructions for setup and use). Target setup should be simple and straightforward for everyone, and no tools are required. Also, the bolt can be moved to accommodate for left or right handed users, which is a very nice feature.
