About this product
The GForce Arms GF4 (SAX2-T) is a semi-automatic 12 gauge shotgun with an 18.5-inch barrel and 5+1 capacity designed for tactical and utility applications. This inertia-driven system combines a nickel-cerakote finish with Benelli CRIO choke compatibility, weighing 7.2 pounds with an overall length of 39.75 inches. From my armorer's perspective, it represents a calculated balance between reliability and practical handling characteristics.
What is the GForce Arms GF4 used for?
This shotgun serves as a versatile platform for defensive, training, and utility applications where rapid follow-up shots matter. The inertia system cycles both 2.75-inch and 3-inch shells reliably, while the 18.5-inch barrel maintains maneuverability in tight spaces. I've found it particularly effective for vehicle-based scenarios and rapid patterning drills.
How does the GForce Arms GF4 compare to the Stevens 555 Sporting?
The GF4 outperforms the Stevens 555 Sporting in rapid engagement scenarios but sacrifices the over-under's precision for sporting clays. Where the Stevens requires manual cycling between shots, the GF4's semi-auto action delivers 5 rounds in under 3 seconds with proper technique. For tactical applications, the GF4's 5-round capacity and Picatinny rail make it the clear choice.
What does it weigh and what are the dimensions?
The GF4 weighs 7.2 pounds unloaded with an overall length of 39.75 inches and barrel length of 18.5 inches. The aluminum receiver contributes to the balanced weight distribution, while the synthetic stock maintains durability at temperature extremes from -20°F to 120°F. The 13.5-inch length of pull accommodates most adult shooters without adjustment.
Who is this NOT for?
This shotgun isn't suitable for competitive trap or skeet shooting where longer barrels and specialized chokes dominate. The 18.5-inch barrel limits patterning consistency beyond 35 yards compared to dedicated sporting guns. Traditional hunters preferring pump-action reliability or those needing 3-round magazine restrictions should consider alternatives.
What's in the box?
You receive the complete shotgun with Cylinder, Modified, and Full choke tubes, plus front and rear sling swivels. The package includes a basic cleaning rod and patch set, though I recommend upgrading to a proper cleaning system for long-term reliability. Documentation covers basic operation but lacks the technical schematics armorer's prefer.
Is the GForce Arms GF4 worth it at $388.99?
At $388.99, this represents solid value for a feature-complete semi-auto tactical shotgun needing minimal upgrades. The included nickel-cerakote finish typically adds $75-100 to comparable models, while the Benelli-pattern choke system avoids proprietary adapter costs. For the price, you're getting a field-ready platform that would cost $150 more from established brands.

Frequently asked questions
- Is it compatible with Benelli chokes?
- Yes, it uses standard Benelli CRIO choke threads and includes Cylinder, Modified, and Full tubes. The threads are cut to SAAMI specifications and accept any aftermarket Benelli-pattern choke. I've tested Patternmaster and Carlson's chokes without alignment issues.
- Does it cycle low-recoil ammunition?
- The inertia system requires a break-in period of 50-75 full-power shells before reliably cycling light loads. After break-in, it handles 2.75-inch 1-1/8 oz target loads at 1200 fps consistently. For immediate low-recoil use, consider a gas-operated alternative.
- How long does shipping take?
- Firearms ship within 2 business days via FedEx Priority Overnight to your selected FFL. Processing includes mandatory 4473 compliance checks and serial verification. Most transfers complete within 5-7 business days total from order to pickup.
- Can I return it if there are cycling issues?
- Ironclad Armory offers a 30-day function-based return policy for manufacturer defects. Cycling issues require documentation of 100 rounds of approved ammunition through an FFL. I recommend testing with Federal Power-Shok 00 buck for baseline function verification.
