New Gun Crafting Idea

As everybody knows by know that m4’s are super common. So I recently had this idea that guns should be harder to craft. They should requires specific molds for each piece. (Maybe just 3 mold [upper receiver, lower receiver, and stock]). Molds can be found in old factory’s. Also You can find the 3 pieces of the gun and find rubber mold. And you can create the 3 molds and make more m4’s. Without a mold you can only make makeshift guns like in fallout. I’m not sure about it but do you guys think molds should have a decay function?

There is already a thread about this.

About gun molds?

Yes i must say, this thread sounds very familiar…
