I suspect you will have to use something like DPL. Here's how it would work:
 * 1) On the weapon page you would add it to a category or add a template that adds the page to a category.
 * 2) Your navbox would use DPL to generate a list of links based on what is in a specific category.

The problem with this method is that users are known to add categories to pages incorrectly, so you might get junk in your navbox. Also, DPL is not installed in Fandom wikis by default and is pretty complicated and will take much experimentation to do what you want.

You could try to use DPLforum to make you list of links, if you don't need all the bells and whistles of full DPL. It is simpler and is installed by default on Fandom wikis.
