The EAA Girsan MC312 Sport Shotgun 12 ga. 24 in. Black Pistol Grip 3 in. with Optic is a competition-ready semi-auto built for 3-gun shooters who demand speed and reliability out of the box. This Turkish-made scattergun features a factory-mounted red dot optic, an enlarged loading port for quad-loading, and a rotating bolt system that cycles everything from light target loads to heavy 3-inch magnums.

Key Features
- Factory Red Dot Optic: Low-profile Picatinny rail comes pre-mounted with a red dot — no extra spend, no adapter hassle. You get on target faster, especially in low-light stages.
- Enlarged Loading Port: Machined for quad-loading right from the factory. Why it matters: shaves seconds off reloads in 3-gun, and you don’t need to send the receiver out for porting.
- Rotating Bolt System: Locks up tight for heavy loads, then cycles light target loads reliably. According to Girsan specs, this bolt design reduces felt recoil and improves extraction consistency.
- 24-Inch Barrel with Vent Rib: Raised rib with mid-bead and fiber front sight gives you a clear sight picture if the dot fails. The 24-inch length balances swing speed and velocity for steel targets.
- Red Magazine Tube Follower: Bright red follower gives an instant visual empty check — no guessing if you’re dry at the buzzer.
Who It’s For
This shotgun targets the tech-savvy 3-gun competitor who wants factory upgrades without the custom-gunsmith price tag. It’s also a solid pick for early adopters who want to test red-dot shotgunning without dropping $1,500 on a Benelli M2 with a Taran Tactical kit. If you’re running your first 3-gun match or leveling up from a pump, the MC312 Sport gives you a competitive edge right out of the box.
Pros & Cons
Pros: Factory red dot saves $100+; quad-load port is cut deep and smooth; rotating bolt cycles light loads; threaded for common Beretta/Benelli choke tubes (5 included); price is under $500.
Cons: The included red dot is basic — expect to upgrade it after a season if you shoot in bright sun. The pistol grip is fixed (not AR-style adjustable), so LOP is not customizable without a stock swap.

Per industry data, the MC312 Sport holds roughly 12% of the budget 3-gun shotgun market as of early 2026, making it a serious contender against the Stoeger M3000. The Beretta 1301 is faster and smoother but costs nearly three times as much — the MC312 is the smart choice if you want to spend your budget on ammo and match fees.
FAQ
Does the EAA Girsan MC312 Sport come with the red dot already mounted?
Yes. The factory red dot optic is mounted on the low-profile Picatinny rail and zeroed at 25 yards out of the box. You just attach the rail to the receiver and you’re ready to shoot.
Can I use this shotgun for hunting or just competition?
It’s optimized for 3-gun, but with 5 choke tubes included (C, IC, M, IM, F), you can use it for waterfowl, turkey, or upland. The 24-inch barrel and pistol grip make it less ideal for long-range waterfowl pass-shooting, but it works fine for close-cover hunting.
What shells does the MC312 Sport cycle reliably?
Per Girsan specs, it cycles 2.75-inch target loads (1,200+ fps) and all 3-inch magnums. Some shooters report it needs a 50-round break-in with high-brass loads before it runs light 1 oz. loads consistently.
Are the choke tubes standard Beretta/Benelli pattern?
Yes. The barrel uses the common Beretta/Benelli Mobilchoke thread pattern, so you can swap in aftermarket chokes from Carlson’s, Patternmaster, or Trulock without adapters.
