Daisy takes the credit for the first modern BB gun that uses the 4.4mm BB around 1900. However air guns were around before that. Lewis and Clark carried an Air Rifle on the 1803-1806 expedition with them. It was thought to be a "Girandoni system" PCP rifle. Bartholomaus Giarandoni developed it around 1780. It fired 22 times on one charge, lead balls were 0.462" caliber.
