Muzzle loading firearms are amongst the earliest types of firearms ever made and encompass everything from hand cannons, arquebuses, matchlocks, wheellocks and flintlock muskets and rifles. Originating in around 1250AD in China with the fire lance (a bamboo or metal tube that could shoot ignited gunpowder), muzzle loading firearms gradually spread across the world and increased in sophistication over the next 600 years until superseded by breech loading firearms in the 19th Century. Airsoft muskets are the rarest type of airsoft guns in the industry with the number of model types not even exceeding single digits, KTW is the brand with the most number of airsoft flintlocks with the spring powered KTW Flintlock Airsoft Carbine Sniper Rifle (Spring Power) and the KTW Flintlock Airsoft Pistol (Air Cocking Gun). KTW are also unique in that they have the only commercially produced matchlock airsoft gun in the entire industry in the form of the KTW TANEGASHIMA Matchlock Airsoft Musket Air Cocking Classic Rifle.
