Mac 2 Tactical Marine Wood 12Ga 18.5 Nkl 6Rd$494.99
Availability: In Stock
The SDS Arms MAC 2 Tactical Marine is a 12-gauge shotgun built for home defense and duty use, built around an inertia operating system that cycles reliably across a variety of loads without requiring adjustments or parts swaps. The 18.5-inch barrel with Benelli/Mobil choke tube compatibility lets you dial in patterns for any shot type—bird, buckshot, or slug—while the electroless nickel marine finish resists corrosion in harsh environments. At just 6 lbs 8 oz with a polymer stock and forearm, it remains handy and maneuverable in tight spaces, yet the mechanical design delivers unmatched balance for a working shotgun.
The Tactical Marine comes sighted and ready: a fully adjustable ghost ring rear sight pairs with a protected blade front post topped with a white dot, both windage/elevation adjustable for precise aiming. The receiver ships drilled and tapped from the factory with a Picatinny rail already installed, so mounting an optic, light, or other accessories takes minutes. Whether you're outfitting for home security, duty applications, or harsh coastal environments, this shotgun's straightforward controls and robust construction make it reliable under pressure.
SDS Arms designed the MAC 2 series for broad compatibility with M2 Benelli aftermarket parts, furniture, and accessories—meaning you can customize the platform to fit your role without hunting for proprietary components. The 3-inch chamber accepts standard and magnum loads, and the 5+1 capacity gives you six rounds on board. This is a no-nonsense, low-maintenance shotgun that handles like it was born in a defensive scenario.
