An air gun is almost any gun that launches projectiles pneumatically with compressed air or other gases that are pressurized mechanically without regarding any chemical type reactions, as opposed to a firearm, which depends on an exothermic substance oxidation (deflagration) of combustible propellants to create propulsive energy. Both long gun and handgun varieties (air rifle and air pistol) typically propel metallic projectiles, that are either diabolo-shaped pellets, or spherical photographs called BBs. Certain types of air guns (usually rifles) could also propel darts or arrows.
The first air guns were developed as soon as the 1500s. They are found in hunting, sporting and warfare. Modern air guns use one of three types of ability source with regards to the design: spring-piston, pneumatic, and bottled compressed gas (mostly skin tightening and).
