About this product
What is the CZ-USA 1020 G2 Field Sports 20 Gauge? It's a semi-automatic shotgun built for sporting clays and upland hunting that balances modern inertia-driven reliability with traditional walnut aesthetics. Chambered for 3-inch shells and weighing 6.10 pounds unloaded, this 28-inch barrel shotgun delivers consistent patterns across five included choke tubes while maintaining handling characteristics that don't fatigue during long days in the field. With a 4+1 capacity and drilled-and-tapped receiver ready for optic mounting, it bridges the gap between classic field guns and modern competition-ready platforms.
What is the CZ-USA 1020 G2 Field Sports used for?
This shotgun excels in sporting clays and upland bird hunting applications where quick second shots matter. The inertia operating system cycles 2-3/4" and 3" shells reliably without gas system tuning, making it adaptable across different load types during a single hunting session. I've found the 28-inch barrel provides optimal swing characteristics for crossing targets while the bronze-finished receiver reduces glare in open-field conditions.
How does the CZ-USA 1020 G2 compare to the Stevens 555 Sporting 20 Gauge?
The CZ-USA 1020 G2 outperforms the Stevens 555 Sporting 20 Gauge in rapid follow-up shot capability due to its semi-automatic action versus the over-under design. Where the Stevens requires manual cycling between barrels, the CZ cycles automatically with approximately 0.3-second faster split times between shots. However, the Stevens maintains an advantage in immediate choke selection versatility with its dual-barrel configuration.
What does it weigh and what are the dimensions?
This shotgun weighs 6.10 pounds unloaded with an overall length of 48 inches including the 28-inch barrel. The length of pull measures 14-3/8 inches with a 1-1/2-inch drop at comb and 2-1/4-inch drop at heel, creating a natural pointing alignment that matches most adult shooters without modification. The balance point sits 4 inches forward of the receiver, giving it slightly forward-heavy characteristics that aid in swing follow-through.
Who is this NOT for?
This shotgun isn't suitable for shooters requiring maximum capacity or tactical applications where magazine extensions are necessary. The fixed 4+1 capacity limits its usefulness for 3-gun competition stages requiring 8+ rounds, and the traditional walnut stock lacks mounting points for shell carriers. For high-volume shooting disciplines, consider dedicated competition platforms with larger magazine tubes and specialized ergonomics detailed in our competition shotgun guide.
What's in the box?
The package includes the complete shotgun with five choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full), choke tube wrench, and owner's manual. Each choke tube measures 2.5 inches in length with external threads compatible with standard CZ choke patterns. The factory packaging includes foam inserts that protect the walnut finish during shipping, though I recommend immediate inspection for transit damage given the delicate nature of wood furniture.
Is the CZ-USA 1020 G2 worth it at $694.99?
At $694.99, this shotgun offers legitimate value for shooters needing reliable semi-automatic performance without premium price tags. The inclusion of five choke tubes represents approximately $120 worth of accessories if purchased separately, bringing the effective firearm cost closer to $575. Compared to Turkish-made alternatives at similar price points, the Czech manufacturing pedigree and CZ's stateside warranty support justify the investment for serious field use.

Frequently asked questions
- Does this work with aftermarket choke tubes?
- The CZ-USA 1020 G2 uses standard CZ choke tube threading compatible with aftermarket options from manufacturers like Carlson's and Briley. The threads measure 0.835x28 TPI, matching most European-pattern choke systems. Always verify compatibility codes before purchasing additional chokes.
- Can I mount optics on this shotgun?
- Yes, the receiver comes drilled and tapped with 6-48 thread pattern accepting standard shotgun scope bases. The mounting surface provides 1.5 inches of rail space suitable for low-profile red dot mounts. I recommend using Loctite 242 on mounting screws to prevent vibration-induced loosening during recoil.
- How long does shipping take to FFL dealers?
- Standard shipping to licensed FFL dealers typically takes 3-5 business days from order verification. All firearms shipments require signature confirmation and direct delivery to the registered FFL address. Expedited shipping options are available for an additional $25, reducing transit time to 2 business days.
- Does this come with a warranty?
- CZ-USA provides a 5-year limited warranty covering manufacturing defects when purchased new. The warranty requires registration within 30 days of purchase and excludes normal wear, cosmetic damage, or modifications. Warranty service typically completes within 10-14 business days at their Kansas City service center.
