A wind-gun can be described in a number of ways. Some synonyms for the term include airsoft gun, pellet gun, BB gun, air gun, and spring gun. These guns are typically powered by compressed air, carbon dioxide, or a spring mechanism, and fire small pellets or BBs. They are popular among hobbyists and shooting enthusiasts for their accuracy and low-impact options for target practice. Other similar terms for these firearms include pneumatic guns, CO2 guns or pistols, and break-barrel guns. Essentially, any gun that uses compressed air or gas to propel a projectile can be considered a wind-gun.
