Mossberg 500A Shotgun, 12 Gauge, 28″ Barrel

The Mossberg 500A chambered in 12 Gauge with a 28-inch barrel is the quintessential American pump-action field gun, widely recognized for its rugged reliability and exceptional versatility. While the physical measurement of the barrel often gauges out to 27.5 inches depending on the specific manufacturing run, Mossberg officially catalogs and brands this as their standard 28-inch Ventilated Rib Field Barrel.
