The MAC 2 Tactical Marine delivers reliable semi-automatic performance in a corrosion-resistant package built for demanding environments. This 12-gauge shotgun combines marine-grade materials with tactical features for professional and sporting applications.

What Makes This Different

The electroless marine nickel finish on the steel barrel provides superior corrosion resistance compared to standard blued finishes. The integrated Picatinny rail system allows direct optic mounting without additional modifications. The 3-inch chamber capability handles everything from standard 2¾-inch shells to powerful 3-inch magnum loads.
