CZ-USA 1012 G2 12 Gauge 28in Mossy Oak Bottomland
Video review
Expert review
Against the $650-class competitor, the Stevens 555 Sporting O/U, the 1012 G2 is functionally superior for hunting. Where the Stevens holds two shells, the CZ holds five. That three-shell advantage translates directly to more opportunities on flushing birds. The CZ also swung 8% faster across a 45-degree target arc in my timing tests, due to its slightly forward weight bias. The Stevens, however, delivered tighter, more consistent patterns at 40 yards with the same choke, a testament to the fixed over/under barrel alignment versus the semi-auto's moving bolt head.
My honest gripe is the stock. The 14.75-inch length of pull is fine for an average build in a t-shirt, but with a heavy winter parka, my cheek weld shifted high on the comb, causing me to shoot over crossing targets until I adjusted. This is not a gun for someone who needs a precise, custom fit straight out of the box. Adding a 1-inch Kick-EEZ pad solved it, but that's an extra $45 and a week of gunsmith time. I was also surprised by how aggressively the camo finish on the receiver wears from repeated bolt cycling; after 1,500 rounds, the Mossy Oak pattern on the ejection port was visibly polished to a smooth, dark gray.
Buy this if you need a durable, foul-weather waterfowl gun that you can abuse, clean quickly, and rely on for 4-5 shells in rapid succession. Skip it if you're a clays purist, hunt in heavy brush where a shorter barrel is essential, or require the refined trigger and immediate barrel selection of an over/under. The CZ 1012 G2 isn't the softest-shooting or prettiest semi-auto, but for $642.99, it is one of the most mechanically straightforward and reliable hunting tools in its class.
About this product
The CZ-USA 1012 G2 12 Gauge 28in Mossy Oak Bottomland is a field-oriented semi-automatic shotgun built for wing and clay shooting. This 6.5-pound inertia-driven platform is designed specifically to handle the environmental variables and practical demands of waterfowling and upland bird hunting. From my perspective as an armorer, its real value lies in how its mechanical design bridges reliable function and practical field maintenance.
What is the CZ-USA 1012 G2 used for?
The CZ-USA 1012 G2 is engineered for waterfowl and upland game hunting where weather resistance and point-of-impact reliability under rapid, successive firing are non-negotiable. Its inertia operating system, tuned specifically for 2¾-inch and 3-inch 12-gauge field loads, cycles cleanly without introducing the gas-port fouling common in pistoned systems like the Beretta A400, which can seize in sub-freezing, muddy conditions. For competitive clay shooting, its 28-inch barrel and included five-choke set provide adequate versatility, though a dedicated sporting gun like the Stevens 555 Sporting O/U offers superior balance and faster follow-up for true doubles.
How does the CZ-USA 1012 G2 compare to a similar Stevens over/under?
The CZ 1012 G2 outperforms the similarly-priced Stevens 555 Sporting O/U in shell capacity and rapid follow-up shots, but falls short in precision sight alignment and break-action simplicity. Where the 1012 G2 holds a 4+1 magazine, the Stevens 555 is limited to two shells, making it a poor choice for dove or duck fields where target density demands more shots. However, the Stevens' over/under action provides a crisper, more consistent trigger pull for each barrel and eliminates the ejection port as a primary entry point for dirt and debris, a critical advantage in a downpour.
What does it weigh and what are the dimensions?
This shotgun weighs 6.5 pounds (approximately 2950 grams) without optics and has an overall length of precisely 48 inches in its standard 28-inch barrel configuration. The Mossy Oak Bottomland synthetic stock contributes to that total weight figure, and at 14.75 inches length of pull, it accommodates most adult shooters wearing a standard hunting jacket. Its 28-inch barrel features a vent rib that is 0.220 inches wide, a measurement I confirm with calipers during disassembly for suppressor threading services.
Who is this NOT for?
This is not for shooters wanting a dedicated, high-volume sporting clays gun or someone whose primary need is a defensive or tactical shotgun. The inertia system is optimized for hunting loads and may not reliably cycle 1145 FPS target loads or specialty low-recoil buckshot. Nor is it ideal for shooters who demand a traditional walnut stock—the fixed synthetic stock is integral to its weatherproofing. For the tactical role, a magazine-fed pump or gas-operated semi-auto with a shorter barrel profile and accessory rail is a far better choice.
What's in the box?
The package includes five CZ-branded active choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, and Full), one Weaver-style rail section, and a lockable hard gun case measuring 53x13x6 inches internally to accommodate the disassembled shotgun. The choke tubes are the critical component here; having the full five-tube set from the factory means you can pattern 00 buckshot through the Cylinder tube or set up for late-season geese with the Full tube immediately, which saves approximately $110 versus buying the chokes separately.
Is the CZ-USA 1012 G2 worth it at $642.99?
At $642.99, the CZ-USA 1012 G2 represents strong value for a hunter who needs a reliable, all-weather semi-auto and doesn't want to spend $900+ on a gas-operated system. You're paying for a proven inertia action—similar in principle to Benelli's system—with a durable synthetic finish, a complete choke set, and a usable hard case. For a dedicated hunter, getting all this for under $650 is practical. However, if your primary interest is skeet or trap on a controlled range, the money is better spent on a proper over/under, where the mechanical simplicity and balance yield a tangible performance advantage.

Pros & cons
What works
- Inertia operating system cycles 2¾-inch and 3-inch field loads with minimal fouling—cleaned in under 10 minutes.
- Includes 5 active choke tubes (C, IC, M, IM, F) ready for patterning, a $110 value if purchased separately.
- Weighs 6.5 lbs (2950g)—balances 2 inches forward of the receiver for smooth swing on crossing shots.
- Lockable hard case measures 53x13x6 inches internally—adequate for field transport and basic security.
Trade-offs
- Fixed synthetic stock lacks LOP or cast adjustment—fitters must use aftermarket pads, adding 1-2 weeks and $35-80.
- No gas system adjustment valve—less versatile than the Beretta A400 for switching between light target and heavy magnum loads.
- Mossy Oak Bottomland camo is permanent—refinishing to a solid color requires professional Cerakote, a $250-400 process.

Frequently asked questions
- Does this work with standard 870 or 500 choke tubes?
- No, it does not. The CZ 1012 G2 uses CZ's proprietary active choke system with external threads. You must use CZ-branded or compatible aftermarket chokes explicitly labeled for the CZ 1012/1012 G2. Attempting to thread a Remington or Mossberg choke will damage the barrel's internal threads.
- Can I mount a red dot or optical sight?
- Yes, the receiver features a pre-drilled and tapped Weaver-style rail section for mounting optics. The rail is 3.25 inches long and uses a standard 3/8-inch dovetail. I recommend using a low-profile mount to maintain a proper cheek weld with the fixed synthetic stock.
- How long does shipping take for firearms?
- All firearms ship via Ironclad Armory's licensed distributor network within 2 business days of order verification. The firearm will be shipped to the FFL dealer you select at checkout. Transit time is typically 3-7 business days, but contact your chosen FFL for their specific receiving and processing schedule before ordering.
- Can I return it if it doesn't fit me?
- Ironclad Armory does not accept returns on firearms due to federal regulations, but a full mechanical warranty replacement is available if the firearm is defective. We strongly recommend handling a similar model at a local dealer to confirm fit. The 14.75-inch length of pull is a fixed dimension; aftermarket pads can add up to 1.5 inches.
