Hatfield SAS USA12S3 Complete Specs and Full Gun Specifications

The Hatfield 12 gauge semi-auto shotgun runs via a unique gas/inertia operating system that uses a gas piston to kick the bolt to send it rearward with inertia. This free floating inertia action creates less friction since the bolt is not connected to a heavy bolt carriage and action arms thus allowing the SAS to function dependably with light field loads on up to 3" magnums. The SAS also features a 28" chrome lined barrel vent rib barrel, with screw in chokes. The SAS is a no-nonsense, highly dependable waterfowl gun for a fraction of the price of other leading brands.
