Availability: In Stock
The MAC 1014 Marine is a 12-gauge tactical shotgun built on a proven piston-driven platform that's earned its reputation in military and professional service worldwide. This particular model comes dressed in electroless marine nickel—a corrosion-resistant finish designed to stand up to harsh environments, moisture, and salt air—making it an excellent choice for coastal hunters, boat-based operations, and anyone working in corrosive conditions. With an 18.5" barrel, fixed polymer stock and grip, and a 5+1 round capacity, the MAC 1014 Marine balances firepower with manageability in tight spaces where you need reliability above all else.
What sets the MAC 1014 apart is its self-regulating piston system. Unlike direct-impingement designs, the piston isolates the bolt carrier from excess gas, keeping things cooler and cleaner while firing a wide spectrum of loads—from light target rounds to heavy buckshot and slugs. You get factory-installed ghost ring rear and adjustable blade front sights, both with windage and elevation adjustment, so you're ready to work right out of the box. A Picatinny rail comes preinstalled for optics or accessories, and the 18.5" barrel accepts Benelli/Mobil-pattern choke tubes (1, 3, and 5 included), letting you tune patterns for whatever you're shooting.
The MAC 1014 is designed to be compatible with most aftermarket Benelli M-1014 and M4 parts and furniture, so you can customize the platform as your needs evolve. At 8 lbs and 47.8" overall length, it's compact enough for vehicle carry or tight building clearance yet substantial enough to manage recoil comfortably. This is a no-frills, purpose-built shotgun for hunters and professionals who need a gun that works in the worst conditions and keeps working.

Electroless marine nickel is applied through a chemical process that creates a corrosion-resistant coating without requiring a power source. It's designed to withstand saltwater spray, humidity, and other harsh environmental conditions better than traditional blued or parkerized finishes, making it ideal for coastal operations and saltwater exposure.
Yes. The self-regulating piston design is engineered to cycle reliably with a wide range of 12-gauge 3" loads, from lighter target rounds to heavy buckshot and slugs. The included choke tubes (1, 3, and 5) allow you to adjust patterns and performance for your specific load choice.
