A 12-gauge semi-automatic shotgun called the Mossberg 930 is made for hunters and skeet shooters. The Mossberg 930 series of 12-gauge semi-auto shotguns is one of the newest and most adaptable versions in Mossberg's shotgun range. Shotguns have been Mossberg's trademark for decades. Like all others, the 930 stands for quality and value. The Model 930 line is a big family of autoloaders because there are nearly a dozen different specialized versions available. There are versions offered for competition, turkey, waterfowl, large game, and general outdoor use. The gas system bleeds off extra gases so the gun operates without putting extreme stress on the action. The 930 manages all 2 3/4- and 3-inch rounds without requiring any adjustments at all. It's a smart design. All 930 receivers are threaded and tapped, making it simple to install or remove an optic sight. The shotguns also feature what Mossberg refers to as the "Stock Drop Spacer" system, which enables the user to rapidly and easily change the buttstock's drop and/or cast to suit the shooter and sight system.
