The ATAC S2 Suppressor is a piston-driven airgun that features Gas-Ram System technology, an Airflow Control (AFC) suppressor and a tactical synthetic stock with integrated Picatiny rails attached to both sides of the forend and receiver for mounting accessories. The action cocks with a break-open barrel and is driven by the efficient Gas-Ram System that reduces vibration and eliminates the sound that comes from a traditional spring-driven airgun.
