Based on the winning M3000 field gun, the M3000 sporting is perfectly at home on the skeet range, as well as in the field. The heart of the M3000 is the proven Intertia Driven operating system: simple and efficient with only three moving parts in the bolt for lightning-fast reliable operation. Unlike older gas system guns, the M3000's Inertia Driven action is contained primarily within the receiver, giving the M3000 a better more centered balance and swing. With no propellant gas venting into the action, the M3000 shoots clean and stays clean longer.
