Mac 2 Tactical Marine 12Ga 18.5 Nkl 6Rd$453.74
Availability: In Stock
The SDS Arms MAC 2 Tactical Marine Wood 12-gauge shotgun is a home defense and duty weapon built on proven inertia-driven engineering. With an 18.5-inch barrel, 3-inch chamber, and 5+1 round capacity, it delivers reliable performance in a compact 47.80-inch overall length that doesn't sacrifice balance or handling. The electroless nickel marine finish paired with Turkish walnut furniture creates a weather-resistant platform that holds up in harsh environments while maintaining classic shotgun aesthetics.
What sets this MAC 2 apart is its straightforward operation and flexibility. The inertia system cycles a wide variety of ammunition without parts swaps or adjustments—crucial when you need reliability from field loads to duty rounds. The factory-drilled-and-tapped receiver comes pre-fitted with a Picatinny rail for optics or accessories, while the ghost ring rear sight and adjustable blade front post with white dot give you multiple aiming options out of the box. Both rear and front sights are windage and elevation adjustable, letting you dial in your zero without guesswork.
The 18.5-inch barrel uses the Benelli/Mobil pattern choke tube system—a huge practical advantage for shotgunners. Three choke tubes (1, 3, and 5) ship with the gun, so you can tune patterns for different loads and distances without buying extra barrels. Whether you're patterning for buckshot, bird shot, or slugs, you've got options right out of the box.
SDS Arms designed the MAC 2 series for Benelli M2 compatibility, meaning most aftermarket stocks, furniture, and upgrades in that ecosystem work here. Weigh 6 pounds 8 ounces, it's light enough for extended shooting sessions without being so featherweight that recoil becomes unmanageable. The marine nickel finish handles salt spray and moisture better than traditional blued steel, and the walnut furniture gives you a shotgun that looks as good as it functions.
