BB gun
Quick Summary
A BB gun is a type of air gun that uses compressed air to fire small metal balls, known as BBs. These BBs are typically 0.175 inches in diameter. While often inexpensive, some BB guns can achieve about half the muzzle velocity of firearms and are accurate enough for training at ranges up to 100 feet. They can also be used to hunt small game. The projectiles from an air gun generally do not travel beyond 300 feet. Early air guns used a compressed air reservoir, but later designs incorporated springs or compressed gas cylinders like carbon dioxide.123
