Dual-Stage Noise Reduction System

The Dual-Stage Noise Reduction System™ was designed by world-renowned silencer designer Humbert CTTS.
Its S2 Airflow Control (AFC) Technology combines the functions of an internal air-regulator ring and baffles that work together to reduce noise.
Stoeger Airguns with the Dual-Stage Noise Reduction System are the quietest airguns in their class.
