Modding the Nerf Rival Knockout - A sort of mod guide and review

Thanks to Meaker Arms on Etsy, you can transform this simple, single shot blaster into some really amazing little blasters. And if you have access to a 3D printer they require no additional hardware. The first one I would recommend is the conversion to fire demolisher rockets, it's by far the simplest one to print and install. Rival, short darts, elites and rockets!
