Iver Johnson MF20 Features The Iver Johnson Arms MF20 runs a semi-auto action in 20 GA with a 3 inch chamber cycling a 20 inch black oxide steel barrel for reliable function across a range of 20 gauge loads. The aluminum receiver keeps overall weight down to a manageable 7.04 pounds while still carrying a full-length Picatinny rail on top for mounting a red dot or other optic. Flip up front and rear sights ride along that same rail giving the shooter a fast backup sighting system if an optic is removed or runs out of battery. A 5+1 round capacity fed from the included 5-shot magazines gives the MF20 solid firepower for a 20 gauge semi-auto in this class. The polymer stock includes an adjustable cheekrest letting the shooter dial in proper cheek weld for a consistent sight picture whether running irons or an optic. A Picatinny rail forend extends the accessory options forward accepting a weapon light laser or foregrip for low-light or close-quarters use. Polymer grip panels and an overall length of 38.5 inches keep the MF20 light and maneuverable while three internal threaded chokes let the shooter tailor the pattern to the task at hand. The Iver Johnson Arms MF20 combines a modern tactical shotgun layout with 20 gauge manageability for shooters who want a lighter-recoiling home defense or utility platform.
