This kit contains parts for a broadside conversion where you can use both the rail gun and high yeild missle pods on the rail gun base. This comes with parts to hold the magnets in place with the perfect spacing as well as covers that fit over top giving it a seamless finish.

Here is a guide that is similar to how this can be used:
