The Mossberg SA-20 is a 20-gauge semi-auto shotgun built for shooters who need a shorter length of pull and lighter recoil without sacrificing performance. With a 24-inch ventilated rib barrel and walnut furniture, it delivers a classic shotgun feel in a package that works for younger hunters, smaller-framed shooters, or anyone who prefers a more nimble gun in the field. The 20-gauge cartridge kicks less than 12-gauge while still delivering effective shot patterns for upland game, clays, and small-to-medium hunting applications.

The SA-20 chambers 3-inch loads, so you're not limited to short shells—reload with standard or magnum 20-gauge ammunition depending on your hunt. Its 5-round magazine gives you enough capacity for most shooting situations without unnecessary bulk. The ventilated rib and front bead sight provide a clean sight picture for quick target acquisition, whether you're tracking fast-moving birds or breaking clays.

Finished in blue metal with a walnut stock, this shotgun strikes the balance between traditional aesthetics and modern semi-auto reliability. At 40.75 inches overall and weighing 6.25 pounds, it shoulders quickly and won't wear you down during a full day afield. The 12.5-inch length of pull is ideal for youth shooters and adults who prefer a more compact handling gun. The included sport choke set gives you flexibility to adjust your shot pattern for different ranges and game.
