Airsoft pellets are spherical projectiles used in Airsoft gun models. Typically made of plastic, they usually range in size from 5.93 to 5.98 mm in diameter, though select models use 8 mm or 3 mm pellets. Although sometimes called BBs, they are not the same as the 4.5 mm projectiles fired by BB guns.
