The Hatfield SAS 12 is a semi-automatic 12 ga. shotgun featuring a walnut buttstock and forend with deluxe checkering and a recoil absorbing 1″ 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 and a special gas piston is included for use when firing the new ultra-high energy 3 magnum ammunition currently on the market. 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 (F, Mod and IC) are included. The barrel finish is high gloss black chrome to match the receiver. Magazine capacity is 4 1 rounds, but with a magazine plug included to limit the capacity to 2 1 rounds. Total weight is approximately 7.75 lbs.
