Description
The GForce Arms GF4 (SAX2-T) 12 Gauge, 18.5 in, 5+1 is a semi-automatic shotgun built for the whole family. It uses an inertia-driven system that cycles 2.75-inch and 3-inch shells without the gas blowback that can bother new shooters. The adjustable tactical stock, nickel finish, and ghost-ring sights make it a practical choice for home defense, range days, and teaching proper shotgun handling.

Key Features
- Inertia-Driven Action — Why it matters: No gas system means less fouling, easier cleaning, and reliable cycling for lighter loads. Your young shooter won’t get discouraged by failures to eject.
- Adjustable Tactical Stock — Why it matters: The length of pull adjusts to fit smaller or larger frames. That means a comfortable, consistent cheek weld for everyone from a 5-foot teen to a 6-foot parent.
- Nickel Finish on Receiver and Barrel — Why it matters: Nickel resists corrosion and wipes clean quickly. After a rainy day at the range, you can spend more time teaching and less time scrubbing.
- Ghost-Ring Rear Sight and Fiber-Optic Front Sight — Why it matters: Ghost-rings give a fast sight picture for moving targets, while the fiber-optic front glows in low light. Perfect for teaching sight alignment under any condition.
- Top Picatinny Rail for Optics — Why it matters: Mount a red dot for faster target acquisition. Beginners can learn with irons first, then add an optic as their skills grow.
Who It’s For

FAQ
Will this shotgun cycle light target loads reliably?
Yes, the inertia system cycles most 2.75-inch target loads with 1-1/8 oz of shot or more. For very light 7/8 oz loads, you may get occasional short strokes until the action breaks in. Per GForce Arms specs, a 100-round break-in with full-power loads is recommended.
Can I mount a red dot sight on this shotgun?
Yes. The top Picatinny rail accepts most red dot and reflex sights. We recommend a low-profile dot to maintain a natural cheek weld with the adjustable stock.
What chokes does this shotgun use?
It uses Benelli CRIO choke threads, which are compatible with many aftermarket chokes. The shotgun includes a cylinder choke for defensive use. You can swap to improved cylinder or modified for clays.
Is this shotgun legal in all 50 states?
It has an 18.5-inch barrel and overall length over 26 inches, so it meets federal requirements for a non-NFA shotgun. Some states have magazine capacity limits, so check local laws before ordering.
How do I clean the inertia system?
Field strip by removing the bolt and trigger group. Wipe the inertia spring and bolt face clean. Avoid over-lubricating — inertia actions run best with light oil. The nickel finish makes cleaning the barrel and receiver quick.
