GFORCE GF25 12GA 18.5" Shotgun - Bronze Cerakote Finish

The Gforce GF25 12GA 18.5" shotgun is a gas-operated, piston-driven semi-automatic built on the AR platform for hunters, sport shooters, and home defenders who want serious versatility without compromise. This magazine-fed workhorse handles 2¾" and 3" shells—from target loads to slugs to buckshot—with the same reliability you'd expect from a modern tactical rifle. The 18.5" barrel keeps things maneuverable in tight spaces, while the overall 38" length strikes a balance between control and handling. Weighing in at 8 lbs, it's substantial enough to manage recoil without feeling unwieldy during extended range sessions.

Built around MKA 1919 magazine compatibility, the GF25 ships with one five-round magazine and accepts common aftermarket options. The barrel is threaded for choke tubes (cylinder, modified, and full included) that use standard Benelli/Mobilia threads—swap them out for different shot patterns without guessing. Gas operation demands a minimum velocity of 1,300 fps to cycle reliably, so lightweight target loads may disappoint, but standard and magnum hunting ammo will run all day. The bronze Cerakote finish resists corrosion and wear, making this a shotgun that'll still look good after a season in the field or on the training line.

Accessory-ready from the factory, the GF25 features a full-length top Picatinny rail for red dots, magnified optics, or other mounted systems, plus a bottom rail for grips and other attachments. QD sling mounts let you run your preferred support without drilling or permanent modifications. Flip-up iron sights come standard for backup aiming, an adjustable cheek rest helps you dial in a solid sight picture behind your optic of choice, and the rubberized pistol grip ensures a secure hold even when your hands are wet or gloved. The aluminum free-floated handguard keeps the furniture light and the barrel cool.

Whether you're running a duty course, hunting waterfowl, or building a versatile home defense platform, the GF25 brings AR ergonomics and modularity to the shotgun world—a growing segment among shooters who want rifle-like controls on a shotgun receiver.

Yes. The GF25 has a full-length Picatinny rail on top for mounting red dots, magnified scopes, or other optics. There's also a bottom rail for tactical attachments. Flip-up iron sights come standard as a backup aiming method.

What chokes come with the GF25, and are they easy to swap?

The GF25 includes cylinder, modified, and full chokes that use standard Benelli/Mobilia choke threads. You can swap them out to adjust your shot pattern for different hunting or sport shooting scenarios.
