The Iver Johnson MF20 20 Gauge Semi-Auto Shotgun blends an AR-style layout with a magazine-fed system for shooters who want familiar controls in a shotgun platform. Built around a black aluminum receiver with a full-length Picatinny rail, it uses a 20-inch steel barrel and 3-inch chamber to handle a wide range of 20 Gauge loads. The synthetic tactical stock features an adjustable cheek rest, while the aluminum forend and accessory rails support lights, grips, and other add-ons.

This MF20 configuration includes removable flip-up sights, a fiber optic front sight, and a muzzle brake, giving the shooter clear sight options and manageable recoil for extended range sessions. Two detachable 5-round magazines and three internal threaded chokes make it adaptable for general range use, training, and recreational hunting. The combination of modular features and straightforward semi-automatic operation reflects Iver Johnson’s focus on practical design and dependable performance.
