Mossberg is the exclusive shotgun sponsor of Halo Waterfowl, whose professional hunters will use Mossberg's newest 940 Pro Waterfowl, finished in Realtree Legacy, throughout their hunting season. All 940 Pro Waterfowl shotguns now come optic-ready, with patent-pending receiver cuts that accept direct mounting of Shield RMSc-pattern micro dot sights, improving eye alignment and target acquisition. Inside, you will find a host of corrosion-resistant internal parts-including a boron-nitride-coated gas piston, magazine tube, and hammer and sear-for improved performance in the blind, in the pit, or while traversing upland fields.
