Girsan MC312 12GA Semi-Auto Shotgun – Inertia-X Drive, 28” Barrel, 3” Chamber, Synthetic Stock
The Girsan MC312 Inertia-X 12-gauge semi-automatic shotgun is quickly gaining attention for its reliability, simplicity, and low-maintenance performance. Built around the advanced Inertia-X Drive System, this shotgun eliminates the need for gas operation—keeping fouling out of the action and reducing cleaning time. The result is a cleaner, smoother-shooting firearm that performs consistently in the field or at the range.
Designed with durability and balance in mind, the MC312 features a lightweight aluminum-alloy receiver paired with a 28-inch barrel crafted from specially coated steel for enhanced longevity and corrosion resistance. Its streamlined internal design uses just a few core components, making it one of the simplest and most dependable inertia-driven shotguns available today.
Ergonomics are a strong point, with a synthetic stock, rounded rubber recoil pad, and a comfortable 13.5” length of pull for improved handling and reduced felt recoil. The ventilated rib and fiber optic front sight provide fast target acquisition, while oversized controls—including the bolt release and charging handle—ensure easy operation even in challenging conditions.
Each shotgun undergoes strict quality control testing before leaving the factory, ensuring reliable function right out of the box.
