Description
The CZ 1020 G2 Field 20 Gauge 28″ Mossy Oak Camo is a purpose-built semi-automatic shotgun that weighs just over six pounds, making it a joy to carry through a long morning in the duck blind or a walk behind a good bird dog. Per CZ-USA specs, the inertia-driven system is adapted from their proven 1012 G2 platform, delivering reliable cycling with light 2¾” target loads up to heavy 3” magnums. The Mossy Oak Shadow Grass Blades finish blends into marsh, field, and timber, while the extended choke set gives you five options to dial in your pattern for doves, pheasants, or waterfowl. This is a field gun built for the man who wants one shotgun that does it all without the extra weight of a gas system.

Key Features
- Inertia operating system – Why it matters: fewer moving parts means less maintenance and more reliable cycling in dusty or muddy conditions, and it keeps the gun lighter than gas-operated alternatives.
- 28” barrel with 3” chamber – Why it matters: the longer barrel gives you a smooth swing on crossing birds, while the 3” chamber lets you shoot steel or bismuth loads for waterfowl without worry.
- Five extended chokes (C, IC, M, IM, F) – Why it matters: you can switch from tight patterns for long-range geese to open patterns for close-flushing quail without buying extra chokes.
- Mossy Oak Shadow Grass Blades camo – Why it matters: this pattern breaks up the gun’s outline in flooded timber, cut corn, or grassy fields, giving you an edge on wary birds.
- 4+1 magazine capacity – Why it matters: you get three shots in the gun plus two extras for a quick follow-up on a double or a late-arriving bird.
Who It’s For
This shotgun is for the Southern shooter who spends more time in the field than at the range. It’s for the dove hunter who wants a light, fast-handling gun that won’t wear him out after a hot September afternoon. It’s for the duck hunter who needs a reliable inertia gun that will cycle in freezing temperatures without the gas system freezing up. It’s for the man who appreciates a traditional field gun with modern camo and a price that leaves room for shells and a good vest.
Pros and Cons
- Pro: Lightweight at just over six pounds, easy to carry all day.
- Pro: Inertia system is simple to clean and maintain.
- Pro: Extended chokes make pattern tuning quick.
- Con: Some light target loads under 1 oz may not cycle reliably until the gun is broken in. Per CZ-USA, a box of heavy field loads helps seat the spring.

FAQ
Will the CZ 1020 G2 cycle 2¾” target loads reliably?
Yes, but it may need a break-in period. Per CZ-USA, run a box of 1-oz field loads through it first. After that, most 2¾” loads cycle fine.
Can I use this shotgun for waterfowl hunting?
Absolutely. The 3” chamber handles steel and bismuth loads, and the Mossy Oak Shadow Grass Blades camo blends into marsh and timber. Just make sure you use non-toxic shot where required.
Does it come with a shim kit for adjusting drop and cast?
No, the 1020 G2 Field does not include a shim kit. The stock is fixed, but the comb is straight and fits most shooters well. If you need custom fit, a gunsmith can add a pad or adjust the stock.
What chokes are included with the CZ 1020 G2?
Five extended chokes: Cylinder, Improved Cylinder, Modified, Improved Modified, and Full. They are marked and easy to swap in the field.
