CSS Content for a Swep.Base?

Hey guys I’m sure this is a really stupid question but I am working on a gamemode and I need a handful of basic weapons and I am too lazy/stupid to code my own weapons from scratch. I was wondering if I could somehow use the CSS weapons included with GMOD for the base then make basic sweps to control ammo etc.

Thanks!!!

Does the CSS weapons included with gmod have a base? Or am I shit out of luck and will have to code weapons from scratch?
