For hunters and shooters looking to step up to an autoloader, the Mossberg 930 is the way to go. This gas-operated autoloading shotgun excels in every environment you do, from walking cornfields to sitting in stands to hunkering down in a marsh. The 930 handles 12-gauge, 2-3/4" and 3" ammunition with ease, from low brass target loads to non-toxic magnum rounds to the latest in sabot slug ammo. The smooth, contoured design and Mossberg Uni-Line receiver delivers instinctive eye/rib alignment for instant target acquisition. Each 930 includes a complete set of specially designed spacers for quick adjustment of the horizontal and vertical angle of the stock, bringing a custom-feel and fit to every shooter. A self-regulating gas system cushions the recoil. There's even an EZ-Empty magazine button when the day is done. 930 models also feature a cocking indicator that protrudes from inside the trigger guard and a drilled and tapped receiver for convenient scope base installation. Waterfowl models have a ported barrel and a ventilated rib and comes with a set of interchangeable Accu-Choke tubes.
