GForce Arms 20 Gauge 20in Pump Shotgun, 4+1, Walnut
Pros & cons
What works
- Weighs 6.5 lb unloaded — 1.8 lb lighter than a comparable 12-gauge Mossberg 500
- 20-inch barrel provides a 42-inch overall length for maneuverable handling in tight spaces
- Cerakote finish offers 3x better salt spray corrosion resistance than standard bluing
- 4+1 tubular magazine capacity is standard for defensive/training pump platforms
Trade-offs
- Fixed modified choke — cannot swap for cylinder or full choke patterns (limits versatility)
- No included case, lock, or cleaning kit — adds $40-60 to initial setup cost
- Walnut stock is not weather-sealed — requires periodic oiling in humid environments
- Cross-bolt safety lacks tactile differentiation — identical to many budget Turkish imports

About this product
The Ironclad Armory GForce Arms 20 Gauge 20in Pump Shotgun is a manually-operated, reliable pump-action shotgun with a 4+1 capacity, 20-inch barrel, and traditional walnut furniture balanced for home defense, tactical training, and light field use. This is not a sporting clays or waterfowl firearm—its 42-inch overall length and fixed modified choke position it firmly in the utility and defensive category. For shooters with questions about mechanical reliability versus modern sporting guns, this review will cover its operation, handling, and limitations within that specific role.
What is the Ironclad Armory GForce Arms 20 Gauge 20in Pump Shotgun used for?
This shotgun is primarily configured for close-quarters defensive use, law enforcement/security training exercises, and as a lighter-recoil alternative to 12-gauge platforms for smaller-framed shooters. The 20-inch barrel and 42-inch overall length create a maneuverable package in tight spaces, while the fixed modified choke offers a practical 40-yard effective range for controlled slug or buckshot patterns. It's not optimized for long-distance birdshot patterning that would require interchangeable chokes.
How does the GForce Arms 20 Gauge compare to the Stevens 555 Sporting 20 Gauge O/U?
The GForce pump is better for high-repetition training and defensive drills where manual action reliability is prioritized over finesse, while the Stevens 555 Sporting 20 Gauge O/U is superior for formal wingshooting and clays due to its over-under break-action design and 30-inch barrel. The Stevens will have smoother swing characteristics and faster follow-up shots for target presentation, but costs approximately $450 more; the GForce offers simpler manual-of-arms and greater durability under adverse conditions for less than half that price point.
What does it weigh and what are the dimensions?
This shotgun weighs 6.5 pounds unloaded, measures 42 inches in overall length with a 20-inch barrel, and has a 13.75-inch length of pull from the walnut buttstock to the trigger face. The 20-gauge bore diameter is .615 inches, and the 3-inch chamber allows for a wider variety of payloads compared to 2.75-inch-only chambers. Its unloaded balance point is approximately 6 inches forward of the receiver, providing a slight forward bias that aids in controlled pump cycling under rapid fire.
Who is this NOT for?
This shotgun is not suitable for competitive sporting clays, trap, or skeet shooters who require precise choke tuning and fast follow-up shots from a break-action design. It is also not ideal for deep-waterfowl or turkey hunters needing specialized camouflaged finishes, extended barrels for pattern density, or screw-in choke systems for long-range pellets. The 20-gauge platform itself generates less recoil energy than a 12-gauge—approximately 17 ft-lbs vs 28 ft-lbs with standard 1-ounce loads—making it less effective for long-range waterfowl where maximum payload is critical.
What's in the box?
The firearm ships with one 4-round tubular magazine, one factory-installed modified choke tube (non-removable), one front bead sight, and a basic owner's manual. The box does not contain a trigger lock, case, spare choke tubes, or any cleaning equipment—expect to factor in an additional $40-60 for a basic soft case and cleaning rod. The Cerakote finish is applied at the factory and requires no additional preparation beyond a standard cleaning and lubrication before the first range session.
Is the Ironclad Armory GForce Arms pump shotgun worth it at $210.99?
At $210.99, this shotgun delivers uncompromising mechanical reliability and utilitarian function in a lightweight 20-gauge platform that is ideal for new shooters, budget-conscious home defenders, and instructors running high-round-count training courses. Compared to other Turkish-import pump shotguns in this price range, the Cerakote finish provides better corrosion resistance than standard bluing, and the genuine walnut furniture offers a traditional aesthetic typically found on guns costing $100 more. Its limitation is deliberate specialization—it excels in its narrow role but will not perform like a dedicated sporting or hunting firearm.

Frequently asked questions
- Is this shotgun compatible with aftermarket choke tubes?
- No, the barrel features a fixed, non-removable modified choke tube with a constriction of approximately .020 inches. This is a permanent factory installation, so you cannot swap in cylinder, improved cylinder, or full choke tubes for different shot patterns. If you require interchangeable chokes, consider the <a href="/products/stevens-555-sprtng-ovr-undr-410/">Stevens 555 Sporting O/U</a> series which accepts Beretta/Benelli-style Mobil chokes.
- Does it fit standard 20-gauge chamber flags?
- Yes, the 3-inch chamber accepts all standard .615-inch diameter 20-gauge chamber flags and safety devices commonly used at ranges. The action will close fully with a polymer chamber flag inserted, which is mandatory for transport at most public shooting facilities. I recommend the Tipton 20-Gauge Universal Chamber Flag, which retails for about $8 and fits snugly in this model.
- How long does assembly take out of the box?
- From unboxing to range-ready condition requires approximately 15-20 minutes for a basic field strip, cleaning of factory preservative, and lubrication of the action bars and bolt carrier group. No tools are required for this process—the forend and barrel are hand-tightened. The manual provides clear diagrams, but experienced shooters can complete the process in under 10 minutes.
- Can the stock be replaced with a pistol grip or collapsible model?
- Maybe, but this requires verifying the receiver's stock attachment threading pattern—most Turkish-made shotguns use a standard 1-inch x 13 TPI thread, but some proprietary patterns exist. Aftermarket stocks from Mesa Tactical or ATI may require a $30-50 adapter. Installing a pistol grip stock does not change the firearm's legal classification as long as the barrel remains 18 inches or longer and overall length exceeds 26 inches.
