Pneumatic weapons are devices that use compressed air or gas to propel projectiles. Common examples include air guns and paintball markers. These weapons operate by compressing air in a chamber, which is then released to push a projectile out of the barrel. They are often used for recreational shooting, training, and some competitive sports. Unlike traditional firearms, pneumatic weapons do not rely on gunpowder, making them quieter and often easier to handle. They can vary in power and design, with some models designed for precision shooting and others for fun activities like paintball or airsoft.
