Possible issue with Gamemode to Coderhire?

I’m really not sure if this is the right place to ask, but I have no idea how to contact anyone of authority at coderhire.

For the past few months I’ve been putting together a gamemode (which I plan to sell online) that I want to be as customizable as possible and I’d like the creation of custom weapons, maps, other game elements to be as painless as possible. In regards to weapons, I’m here to ask if using the iron-sight script made by Garry (old css weapons) or the TTT devs in said gamemode would cause a legal issue (I mean this script in particular since its the most commonly used one in custom weapons)

feedback appreciated

It’s fine if you use someone else’s code as long it’s minimal and you credit the person; you should be fine since it is official code from Garry’s Mod devs.
