The Mossberg SA-20 All Purpose Field is a 20 gauge semi-auto shotgun (Mossberg part no. 75772) that uses a smooth-cycling, gas-operated system for lightweight, soft-shooting performance on the range or in the field. A black synthetic stock and matte blued vent rib barrel give it a durable, no-nonsense look built for hard use, while a metal bead front sight keeps the sight picture simple and fast. It ships with Mossberg International’s Sport Set of five choke tubes, covering everything from close-range clays to longer crossing shots. Between the vented gas system and soft-shooting 20 gauge platform, this is a shotgun built equally for hunting and target work.
