The TriStar Viper G2 Pro 20 Gauge 28in FDE Terra Bayou is a gas-operated semi-auto shotgun built for shooters who demand reliable cycling across target loads and waterfowl shells. It pairs a 28-inch vent-rib barrel with a flat dark earth Cerakote receiver and a Mossy Oak Terra Bayou synthetic field stock, giving you weather-resistant handling and a low-glare finish that blends into marsh or timber. Controls are oversized for gloved-hand use, and the gas system cuts felt recoil so you can stay on target for fast follow-ups. This is a field-ready 20-gauge that punches above its weight class.

Key Features
- Gas-Operated Action — WHY IT MATTERS: Reduces perceived recoil by up to 30% compared to inertia systems, so you can run lighter target loads without short-stroking and stay on target for faster second shots.
- 28-Inch Vent-Rib Barrel — WHY IT MATTERS: The longer sight radius improves swing and pointability for crossing birds and clay targets, while the ventilated rib dissipates heat and reduces mirage on hot days.
- Oversized Controls — WHY IT MATTERS: The bolt release, safety, and charging handle are enlarged for easy manipulation even with gloves on, which is critical when your hands are wet or cold in the blind.
- Mossy Oak Terra Bayou Camo — WHY IT MATTERS: This pattern blends into flooded timber, marsh grass, and muddy banks, giving you concealment without adding bulk or shine.
- Flat Dark Earth Cerakote Receiver — WHY IT MATTERS: Cerakote resists rust, scratches, and solvents better than standard bluing, so your receiver stays looking tight even after seasons of saltwater and mud exposure.
Who It’s For
This shotgun is for the tech-forward hunter who wants a lightweight 20-gauge that cycles everything from 7/8 oz target loads to 3-inch magnum waterfowl shells. It fits shooters who appreciate modern coatings like Cerakote and camo patterns that actually work in the field. If you’re tired of fighting heavy 12-gauge recoil and want a semi-auto that runs clean out of the box, the Viper G2 Pro is your next workhorse.
Pros / Cons
- Pros: Reliable gas system, low recoil, lightweight at 6.5 lbs, Cerakote finish resists corrosion, Mossy Oak Terra Bayou camo blends into diverse wetlands, oversized controls for gloved use.
- Cons: The synthetic stock has a slightly hollow feel compared to higher-end Turkish or Italian shotguns, and the included choke tube selection is limited to three (IC, M, F) — you may want to buy aftermarket chokes for specialty loads.

FAQ
What loads does the TriStar Viper G2 Pro cycle reliably?
Per TriStar specs, the gas system cycles 2.75-inch target loads (7/8 oz and up) and 3-inch magnum waterfowl loads without adjustment. Light 1-ounce loads may require a break-in period of 50–100 rounds. Use high-velocity loads for the first few boxes to seat the action springs.
Can I use this shotgun for 3-gun or tactical competition?
While the Viper G2 Pro is built for field use, the 28-inch barrel and gas system make it a solid choice for 3-gun matches that allow 20-gauge. The oversized bolt release helps with speed reloads, but you’ll want to add a Nordic Components +2 extension for extra capacity.
Does the Cerakote receiver hold up to saltwater and mud?
Yes — FDE Cerakote is a ceramic-based finish that resists corrosion and abrasion far better than standard bluing or anodizing. After a season in coastal marshes, the receiver should show minimal wear if wiped down and oiled occasionally.
What chokes are included, and can I use aftermarket ones?
The shotgun ships with three Beretta/Benelli Mobil-style chokes: Improved Cylinder, Modified, and Full. You can swap in any aftermarket Mobil-thread choke from brands like Carlson’s or Patternmaster for tighter patterns or steel shot compatibility.
According to NSSF data, 20-gauge shotguns now account for nearly 18% of all new shotgun sales, driven by hunters seeking lighter recoil and faster handling. The Viper G2 Pro fits that trend perfectly.
