Mossberg 75771 SA All 20 Gauge 3" 5-Round Shotgun

The Mossberg 75771 SA All Purpose 20 Gauge 3" semi-automatic shotgun is a reliable, gas-operated platform designed for shooters who demand versatility without compromise. Chambered in 20 gauge with a 3-inch capability, this full-size semi-auto delivers reduced recoil compared to 12-gauge alternatives while maintaining sufficient power for hunting, sport shooting, and home defense applications.

At 8.4 lbs with a 37.2-inch overall length, the Mossberg 75771 balances manageable weight with a stable shooting platform suitable for extended use in the field or at the range. Built on Mossberg's proven gas-operated semi-auto action, the 75771 feeds reliably from a 5-round magazine and cycles both 2.75-inch and 3-inch 20-gauge ammunition without adjustment. The gas system mitigates felt recoil and improves follow-up shot accuracy, a critical advantage during tactical or hunting scenarios where rapid, controlled follow-ups matter.

Law enforcement trainers, civilian shooters, and hunters benefit from the Mossberg 75771's ergonomic controls and natural pointability; the 20-gauge platform is especially valued in training environments where shooter fatigue from repeated 12-gauge recoil compromises fundamentals. The all-purpose profile accommodates a wide range of optics and accessory rails, allowing users to customize the platform for specific mission requirements—whether that means mounting a bead sight for wingshooting or integrating a tactical light and optic for low-light home defense.
