What is a spring gun?
Spring guns are a class of airsoft guns that uses hand compressed spring as a power source. They are the most commonly available type of airsoft gun. Spring guns are available in all styles of guns from pistols to full sized rifles, and more varieties of guns are available as spring guns than any other category of gun. No spring gun can ever shoot in semi-automatic or full-automatic, regardless of markings on the gun. Many spring rifles have selector switches that appear to switch between semi- and full-automatic, but this is only to replicate the look or the real gun.
