The Mossberg SA-20 Field is a lightweight semi-automatic 20 gauge shotgun built for hunters who want less recoil without sacrificing reliability or versatility. This model (75771) pairs a compact, user-friendly platform with a classic field setup—making it equally at home in upland brush, on the clay range, or introducing newer or smaller-framed shooters to shotgun sports. At just 6 pounds and 48.5 inches overall, the SA-20 Field swings fast and carries easy, and the synthetic black stock stands up to hard use in the field.
The 28-inch barrel wears a ventilated rib and sports a simple bead sight for quick target acquisition. The 3-inch chamber handles both 2.75-inch and 3-inch 20 gauge shells, giving you flexibility in load selection depending on game and distance. The tube magazine holds 5 rounds, and the semi-auto action cycles cleanly, reducing felt recoil compared to pump or break-action alternatives. That lighter recoil is one of the big reasons 20 gauges appeal to hunters who shoot all day or younger shooters building confidence.
Out of the box, the SA-20 Field comes with a Sport Set of five interchangeable chokes, so you can tailor your pattern for whatever you're hunting—tight for distance, open for closer work. The matte blued barrel and black synthetic furniture keep maintenance simple and won't snag in brush. With a fixed 14-inch length of pull, it strikes a good balance for most adult shooters; if that doesn't work for your frame, aftermarket stocks and shims are widely available. Whether you're hunting pheasant, quail, ducks, or breaking clays, this Mossberg delivers reliable semi-auto handling in a trim, manageable package.
