Spring powered air rifles are simple, reliable and self contained. Cocking is performed manually by placing a spring under pressure using leverage from a break barrel or underlever mechanism. No air tanks, air pumps or CO2 cartridges are required. "Springers" can be just as accurate as any air rifle, but they create recoil when fired, requiring the shooter to learn their rifle and develop recoil control skills to ensure that pellets consistently hit their mark. For this reason, spring powered air rifles are often the favoured choice of sportsmen who enjoy a more challenging shooting experience and the satisfaction of mastering their weapon.
