Description
There's a reason the Viper G2 keeps showing up in duck blinds, dove fields, and Saturday morning clays squads. TriStar built this 20 gauge around a gas-operated action that soaks up recoil and cycles everything from light target loads up to heavy 3 inch waterfowl loads without needing adjustment. At around 5.8 pounds, it's the kind of gun you can carry all day on an upland hunt and still swing quick when a bird flushes at your feet.
Walnut Looks, Workhorse Guts
The stock and forearm are cut from Turkish walnut with clean cut checkering and a semi-gloss finish, so it has the warm, classic look of a field gun that costs quite a bit more. Underneath the wood, the details are all business: a chrome-lined chamber and barrel for easy cleanup and corrosion resistance, a vent rib with a matted sight plane topped by a fiber optic front sight, and a rubber recoil pad to take the edge off heavier loads. A shim kit comes standard, so you can tweak drop and cast to fit your build and get your eye lined up right down the rib.
Choke Tubes and Smart Touches on the Viper G2
TriStar includes three choke tubes, Improved Cylinder, Modified, and Full, threaded for the widely used Beretta/Benelli Mobil pattern. That means aftermarket options are everywhere if you ever want an extended turkey or sporting choke. The manual E-Z Load magazine cut-off is a handy feature too, letting you swap the shell in the chamber without emptying the magazine, which is great when a goose slips in while you're loaded for ducks.
Why the Viper G2 20 Gauge Earns Its Keep
TriStar backs the Viper G2 with a five-year warranty, and the design gets endurance tested to 5,000 rounds before it ever hits the shelf. For a soft-shooting 20 gauge autoloader that handles clays, doves, quail, and waterfowl with equal manners, this one is tough to beat. It's a lot of shotgun in a trim, good-looking package.

Frequently Asked Questions
Will the TriStar Viper G2 cycle light target loads reliably?
Yes, that's one of the strong points of this gas system. It's designed to run everything from light 20 gauge target loads up to heavy 3 inch hunting loads without any adjustment. Like most gas autoloaders, give it a proper cleaning and light lube after break-in and it will keep cycling the cheap stuff just fine.
What choke tubes fit the Viper G2 20 gauge?
The barrel is threaded for the Beretta/Benelli Mobil choke pattern, one of the most common thread patterns out there. It ships with Improved Cylinder, Modified, and Full tubes plus a wrench and storage box. If you want an extended turkey or sporting choke later, aftermarket options from Carlson's, Briley, and others are easy to find.
Can I adjust the stock fit on this shotgun?
You can. TriStar includes a shim kit standard with the Viper G2, which lets you adjust the drop and cast of the walnut stock to match your build. That's a feature usually reserved for pricier autoloaders, and it makes a real difference in how naturally the gun points for you.
What is the E-Z Load magazine cut-off for?
The manual magazine cut-off lets you open the action and swap the shell in the chamber without feeding a new round from the magazine. It's handy in the field when you want to change loads quickly, like switching to a heavier shell when bigger birds show up. It also makes unloading the chamber alone quick and simple.
