The Mossberg 940 Pro Tactical (brand part no. 85163) is a 12 gauge semi-auto shotgun built for home defense and duty use, pairing an 18.5-inch barrel with an optic-ready receiver and a clean-running gas system. Mossberg cut the receiver to accept low-profile direct mounting of Shield RMSc-pattern micro red dots, putting a fast sight picture within reach without a separate mounting plate. An adjustable stock and quick-empty magazine release round out a shotgun built to be run hard and set up exactly the way its owner needs it.
