BB guns are air guns that shoot small, round pellets called BBs, typically made of steel and coated in copper or zinc. They are designed for target shooting, plinking, and sometimes small game hunting. BB guns use compressed air or gas to propel the pellets, making them less powerful than traditional firearms. These guns are popular for recreational shooting and are often used in shooting sports. Safety is important when using BB guns, as they can cause injury if not handled properly. Users should always wear protective eyewear and follow safety guidelines to prevent accidents.
