"Featuring a shortened 13-1/8"" length of pull, the Stoeger M3020 Compact Semi-Auto Shotgun is ideal for smaller-framed shooters. The M3020 is built around the Inertia Driven system for incredibly fast, reliable cycling of everything from 2-3/4"" field loads to 3"" magnum loads with no adjustments. The Inertia Driven system runs cleaner and cooler that traditional gas systems because it doesn't spray gas and carbon into the action. Integrated swivel studs make it easy to outfit the shotgun with a sling (not included), and an included shim kit lets you adjust drop and cast for a custom fit. The vent rib barrel is topped with a red bar fiber-optic front sight. Includes 3 choke tubes (IC, M, XFT) and wrench.
