The M300 features a simple but robust inertia-driven piston system allowing for a wide variety of shells to be cycled while offering fast follow-up shots with the semi-automatic action. The Sporting series features oversized controls for easier manipulation under pressure along with a weight magazine cap for exceptional balance. Recoil-mitigating ported barrels aid in faster follow up shots and is paired with a broadway-style rib to deflect barrel heat from line of sight. This model is chambered in 12 Gauge and features a 3-inch chamber and a nickel receiver finish. The magazine tube has a 4-shot capacity. Included with each shotgun are three extended choke tubes (C, IC, M) and two specialty choke tubes (SKI1, SK2).
