Improve firearms: rifled barrel

Firearms were developed and improved rapidly in the 17th and 18th centuries. Thanks to inventions in this sphere, firearms became lighter and more effective, and gained better accuracy and range of fire. Rifled handguns - carbines - were added to the arsenals; these firearms possessed a much greater range of fire. Large-calibre buckshot handguns known as blunderbusses were effective at short range.
