How did gunsmiths use the natural resources to build a rifle?

Gunsmiths utilized local Natural Resources to construct rifles by sourcing materials such as iron and steel for the barrel and action, often obtained from nearby mines or forges. Wood from local trees, like walnut or maple, was shaped for the stock, providing both durability and aesthetic appeal. Additionally, natural resources like leather were used for components such as recoil pads or slings. By carefully selecting and processing these materials, gunsmiths ensured the functionality and quality of the rifles they built.
