In this industry, too, springs are components that define exceptional performance characteristics—ranging from the recoil spring in automatic and semi-automatic weapons (responsible for absorbing the bolt carrier's recoil energy after firing and subsequently chambering the next round) to hammer, firing pin, and magazine springs—and that covers only small arms. Springs are also used in all types of vehicles: land-based (tanks, armored personnel carriers), marine (amphibious vehicles, combat cutters, ships, and frigates), and aerial (helicopters, airplanes, and drones).
