The Hatfield SAS USA20W is a semi-automatic shotgun featuring a turkish walnut buttstock and forend with deluxe checkering and a recoil absorbing 0.5" ventilated rubber recoil pad. The SAS operating system is a unique blend of gas and inertia, where a gas piston moves only one inch to kick the bolt rearward and start the bolts inertia travel through the operating cycle; fewer moving parts provides higher dependability. The SAS gas/inertia system operates dependably with most commercially available 2.75" and 3" shells. The gas/inertia action is housed inside a receiver machined from 7075 aluminum finished in a high gloss black anodizing. The SAS 28" barrel is chambered for both 2.75" and 3" shells and features a full length ventilated rib and screw-in chokes; three chokes full, modified and improved cyclinder are included. Magazine capacity is 4+1 rounds, but with a magazine plug included to limit the capacity to 2+1 rounds. Total weight is approximately 7 lbs.
