[quote=&quot;goPostal&quot;]Not to seem like a total n00b, but where does the &quot;classes&quot; folder go? Thanks guys!![/quote]

You don't have to put it anywhere if you want to use one of the mutators.  I just put that there if people want to modify the gun.  Everything in the Classes folder is the source code for the rifle.  All you need is the the .ini and .u files on your server/game.
