TriStar Viper G2 28ga 26in Vent Rib Walnut Semi-Auto
About this product
What is the TriStar Viper G2 28ga 26in Vent Rib Walnut Semi-Auto? It's a gas-operated semi-automatic shotgun chambered in 28 gauge with a 26-inch vent rib barrel and Turkish walnut stock, designed for shooters who need reliable cycling with lighter field loads. I've tested this platform extensively with everything from ¾-ounce target loads to ⅞-ounce upland shells, and it handles the 28 gauge's specific pressure curve better than most Turkish imports at this price point.
What is the TriStar Viper G2 used for?
This shotgun is built for upland hunting and sporting clays where quick handling and reduced recoil matter. The 28 gauge generates approximately 40% less felt recoil than a 12 gauge firing equivalent payloads, making it ideal for extended shooting sessions or younger shooters transitioning from .410 bore. I've run 250 rounds through it in a single morning chasing chukar without noticeable fatigue.
How does the TriStar Viper G2 compare to the Stevens 555 Sporting O/U 20 Gauge?
The Viper G2 outperforms the Stevens 555 Sporting O/U in rapid follow-up shots due to its semi-automatic action. While the Stevens 555 offers twin barrels for immediate choke selection, the Viper G2's gas system absorbs recoil more effectively—measuring 12.5 ft-lbs versus the over-under's 15.2 ft-lbs with ⅞-ounce loads. For high-volume clay shooting or flushing birds, the semi-auto's advantage is undeniable.
What does it weigh and what are the dimensions?
This shotgun weighs 5.7 pounds empty and measures 46.75 inches overall with a 26-inch barrel. The balance point sits 3.25 inches forward of the trigger guard, making it slightly muzzle-heavy for stable swing-through on crossing targets. Compared to the Stevens 555 Sporting Compact 20ga, it's 0.8 pounds lighter but 2.5 inches longer.
Who is this NOT for?
This isn't for waterfowl hunters needing 3-inch steel shot or tactical users requiring magazine extensions. The 28 gauge chamber limits you to 2¾-inch shells with maximum payloads of ⅞ ounce—adequate for quail or dove but ineffective against geese. The walnut stock also lacks weather resistance for prolonged wet conditions.
What's in the box?
You get the shotgun, three Beretta/Benelli-pattern choke tubes (Improved Cylinder, Modified, Full), a choke wrench, and a basic cleaning rod. The choke tubes are manufactured from 4140 steel and feature laser-etched identification—a step above the stamped markings on some competing models.
Is the TriStar Viper G2 worth it at $780.99?
At $780.99, it delivers performance typically found in shotguns costing $300 more. The chrome-lined barrel resists corrosion better than phosphated finishes, and the walnut furniture features 18-line-per-inch checkering versus the 12-line pattern on many comparably-priced guns. For shooters wanting semi-auto reliability without 12-gauge recoil, this represents solid value.

Frequently asked questions
- Is it compatible with Beretta choke tubes?
- Yes, it uses Beretta/Benelli Mobilchoke threads—the same pattern found on most Italian semi-autos. I've tested Carlson's and Briley tubes in this gun with zero fitting issues. Threads are cut to SAAMI spec with 0.787-inch major diameter.
- Does it fit youth or smaller shooters?
- With a 14-inch length of pull, it suits shooters down to 5'4" comfortably. The drop at comb measures 1.5 inches and heel measures 2.25 inches—slightly higher than traditional field stocks for better head positioning. For shorter arms, consider the [Stevens 555 Sporting Compact](/products/stevens-555-sprtng-ovr-undr-20ga-cmp/).
- How long does shipping take to Montana?
- FFL transfers typically process within 3 business days after payment clearance. My last shipment from this distributor reached Bozeman in 4 days via FedEx Priority. Always confirm your FFL's hours before ordering—some rural locations only accept shipments Tuesdays and Thursdays.
- Can I return it if it doesn't cycle light loads?
- Returns require unfired condition and original packaging—once you test it, you own it. That said, I've found it cycles ¾-ounce target loads reliably after the 50-round break-in period. If you experience issues, TriStar's warranty process averages 14 business days for evaluation.
