Description
The MAC 2 Tactical Marine Nickel 12 Gauge shotgun is the Military Armament Corp MAC 2 Tactical Marine with a nickel-plated finish and a fixed black synthetic stock. It is a light inertia-operated semi-auto with an 18.5 inch barrel, 3 inch chamber, ghost ring sights and a drilled-and-tapped receiver with a Picatinny rail.

MAC 2 Tactical Marine Nickel 12 Gauge Overview
Made in Turkey and imported by SDS Arms, the MAC 2 is modeled on the Benelli M2 and accepts most M2 aftermarket parts. The Marine version adds an electroless nickel finish for humid and salty environments, while the polymer stock shrugs off water. It weighs about 6.5 pounds, uses Mobil-thread chokes with three tubes included and has a white-dot front post with an adjustable ghost ring rear.
Built for Wet Conditions
Nickel plating and a synthetic stock make this the low-maintenance choice of the MAC 2 line for boats, docks, coastal homes and duck blinds. Nickel resists rust well but is not stainless, so wipe off salt spray and keep moving parts lightly oiled.

Inertia System Notes
There are no gas pistons, so the action stays clean. Recoil is sharper than with a gas gun when you shoot heavy buckshot or slugs in a 6.5 pound shotgun. Some light target loads may not cycle until break-in, and hanging heavy accessories can affect reliability, so test your loads.
Capacity
Sources differ on this model: Primary Arms lists 4+1 for the synthetic Marine, while others list 5 rounds. Plan on 4+1 with 3 inch shells and verify the count when you first load the tube.

Synthetic Stock and Controls
The fixed synthetic stock is light and weatherproof. The oversized charging handle is easy to find, though reviewers noted it spins freely. The trigger is single stage, near 6 pounds, with smooth creep.
Optics and Patterning
Mount a red dot on the receiver rail if you want faster aiming. Pattern buckshot through each choke at home-defense distances before choosing one.
Breaking In and Maintenance
Run several boxes of full-power shells through the gun before judging reliability with light loads. Keep the bolt clean and lightly oiled, keep oil out of the stock tube area, and check that the choke tube is snug after each session. After a day near the water, wipe the nickel and stock down with a lightly oiled cloth.
Choosing Home Defense Loads
Start with reduced-recoil buckshot and confirm it cycles. Pattern it at the distances inside your home and yard and pick the choke that keeps pellets tight. Keep a few slugs on hand for longer shots, and remember that slugs and buckshot can travel through interior walls, so know what is behind your target.
State Laws and Ownership
Some states regulate semi-auto shotguns and tube capacity. Check your state and local rules before ordering.
