The Disco Double and The Challenger Double


The Disco Double kit is an easy to install, second air tube for your Benjamin Discovery air rifle. The Challenger Double kit is identical to the Disco Double kit except that the tube is 4 inches longer, and adds 28ccs more than the Disco Double kit. With double the air volume, you get double the number of shots.


The kit includes everything you need except for tools and your modified stock (and, of course, your own Benjamin Discovery or Crosman Challenger PCP air rifle!). Standard finish on the air tube and barrel bands is satin black powder coat. Most airgunners will complete the installation in around two hours.
