The G-Force GF25 12ga semi-auto shotgun is a modern, AR-platform 12 gauge that brings rifle-style ergonomics and modularity to shotgun shooting. Built on a gas-operated piston system with a 20-inch chromoly steel barrel, the GF25 handles everything from target rounds to buckshot and slugs—making it equally at home on the range, in the field, or as a reliable defensive tool. The aluminum free-floated handguard and top Picatinny rail give you room to mount optics and accessories, while quick-disconnect sling mounts keep you ready to move.
This is a shotgun that doesn't ask you to compromise on features. The GF25 ships with a cylinder choke, flip-up iron sights, an adjustable cheek rest for a solid sight picture, and a rubberized pistol grip that won't slip when things matter. The magazine-fed design uses MKA 1919 pattern magazines and accepts Benelli-threaded chokes, so you can swap loads and patterns to match your day. Whether you're running 2¾-inch or 3-inch shells, the piston system cycles them reliably—as long as your ammunition hits the 1300 FPS minimum velocity required to operate the platform. At 8 pounds, it's light enough to carry all day and balanced enough to swing naturally.
The GF25 comes finished in black and is built to work hard. Threaded barrel, bottom Picatinny rail for lights or vertical grips, and that adaptable platform mean you'll keep finding new ways to configure it. If you want a semi-auto shotgun that handles like an AR and performs like a proven workhorse, the GF25 earns the role.

The GF25 uses MKA 1919 pattern magazines. It ships with one 5-round magazine. Any MKA 1919-compatible magazine will function in this shotgun.
Yes. The GF25 features a top Picatinny rail that will accept red dot sights, reflex scopes, or other optics mounted directly to it. It also comes with flip-up iron sights as standard.
The GF25 handles 2¾-inch and 3-inch shells, including target loads, buckshot, and slugs. However, ammunition must achieve a minimum velocity of 1300 FPS to reliably cycle the piston system. Low-velocity or light target loads below that threshold may not operate the action properly.
The GF25 accepts Benelli-threaded choke tubes. It comes fitted with a Cylinder choke. Additional tubes in Improved Cylinder, Modified, Improved Modified, and Full are available separately and can be swapped to match your shooting needs.
