Inside the Mossberg 940 Pro shotgun, you will find a durable gas system that allows for up to 1500 rounds between cleanings and a host of corrosion-resistant internal parts (boron-nitride coated gas piston, magazine tube, hammer sear, return spring tube; chrome-lined chamber and bore; and a stainless steel return spring). An enlarged/beveled loading port, elongated elevator, and anodized follower combine for smooth operation. Outside, an adjustable LOP self-draining stock and streamlined forend feature Mossberg signature texturing and a camo finish; Cerakote metal surfaces provide extra protection for the muddiest, wettest hunting conditions; and a front fiber optic sight and ported extended choke tube help put more pellets where they are needed. This Waterfowl model features a 28" vent rib barrel, X-factor extended choke tube, a 4 round magazine tube and a True Timber Prairie camo finish.
