Description
There's something about a bullpup shotgun that just makes people grin at the range, and the GForce Arms GFY-1 delivers that experience without emptying your wallet. By tucking the action and magazine behind the trigger, this 12 gauge keeps a full 18.5 inch threaded barrel while measuring only 28.5 inches overall. That's barely longer than a firearm-classified pump with a fraction of the barrel, so you get real payload velocity and pattern performance out of a package that swings fast and stores easy.
Inside the GFY-1 Bullpup Design
The GFY-1 runs a gas operated semi-auto action fed from detachable box magazines, and it plays nice with MKA-1919 and AR-12 pattern mags and drums, so aftermarket capacity upgrades are easy to find. The 3 inch chamber handles both 2 3/4 and 3 inch shells, and the barrel accepts Benelli Mobil pattern chokes with a Modified tube included from the factory. A rubber recoil pad on the butt takes the edge off heavier loads, and the pistol grip layout keeps the weight balanced back toward your shoulder where a bullpup carries best.
Sights, Rails, and That Flag Finish
Flip-up front and rear sights come standard and fold flat when you want to run a red dot on the full-length top Picatinny rail. There's a second rail on the underside of the forend for a light or vertical grip, which makes a lot of sense on a shotgun this compact. This particular version wears a black and white American flag finish over the aluminum receiver and polymer stock, paired with a black threaded barrel, so it stands out on the rack without looking gimmicky.
Where the GForce GFY-1 Earns Its Keep
At around 7.7 pounds, the GFY-1 is a natural fit for home defense, truck duty, and range days where you just want to burn through a case of birdshot with a smile on your face. Magazine feeding means fast reloads compared to a tube gun, and the short overall length makes it genuinely easy to maneuver indoors or stash in a compact case. For the money, it's tough to find another semi-auto bullpup that brings this much to the table.

Frequently Asked Questions
What magazines does the GForce GFY-1 accept?
The GFY-1 feeds from MKA-1919 and AR-12 pattern magazines, which is great news for aftermarket support. Beyond the included 5-round mag, you can find 10-round sticks and even 15 or 20-round drums from makers like ProMag and SDS. Just make sure whatever you buy is specifically listed as MKA-1919 or AR-12 compatible.
Can the GFY-1 shoot both 2 3/4 and 3 inch shells?
Yes, the 3 inch chamber handles both 2 3/4 and 3 inch 12 gauge shells. Like most gas operated shotguns in this class, it tends to run most reliably with fuller-powered loads, so stick with standard velocity or heavier ammo during break-in. Very light target loads can be hit or miss until the action wears in.
Can I mount a red dot on the GForce Arms GFY-1?
Absolutely. The full-length top Picatinny rail accepts red dots, reflex sights, and other optics, and the included flip-up sights fold down flat so they stay out of the way. There's also a bottom rail on the forend for a weapon light or foregrip, which pairs nicely with the compact bullpup layout.
Does the GFY-1 use interchangeable choke tubes?
It does. The threaded barrel accepts Benelli Mobil pattern chokes, and a Modified tube comes installed from the factory. That's one of the most common choke patterns out there, so finding additional tubes for tighter or more open patterns is quick and inexpensive.
