Introduction
Side-lever air rifles represent a sophisticated evolution in airgun cocking mechanisms, offering shooters an ergonomic alternative to traditional bolt actions. This design, popularized in high-end match rifles, combines smooth operation with precise control. Born from competitive shooting demands, side-lever actions have become increasingly popular in both target and field applications, offering shooters the perfect blend of efficiency and precision. Their distinctive design allows for rapid cycling while maintaining shooting position, making them particularly valuable in competitive scenarios.
