Gunsmithing is the art and science of designing, building, and repairing firearms. It encompasses a wide range of skills, including metalworking, woodworking, and knowledge of ballistics. A skilled gunsmith can modify existing firearms or create custom pieces tailored to a shooter's preferences. In addition to repairs and modifications, gunsmiths often work on the maintenance of firearms, ensuring they function safely and effectively. This profession requires a deep understanding of various firearm mechanisms and the ability to troubleshoot issues. Many gunsmiths also engage in firearm restoration, bringing old or damaged guns back to life.
