A few years ago, Knoxx Industries (who mostly manufacture recoil reduction hardware for rifles and shotguns) started making the Sidewinder - a kit to convert a Mossberg 500 (and a few other similar models) to be able to use either a 6 round box magazine or a 10 round drum (shown above). Unfortunately, they had issues getting the kit manufactured at their target price, and have since discontinued production and sales. This makes finding a photo of a Sidewinder-equipped Mossberg a bit of a challenge. Hats off to the AnarchAngel for his blog post about the Sidewinder shown here.
