About this product

The TriStar Viper G2 Pro 12ga 28in Semi-Auto Shotgun is a gas-operated field shotgun built for reliability with a classic aesthetic. It represents a specific value segment in the modern sporting market, where Turkish manufacturing meets a traditional American hunting profile. At 6.8 lbs and chambered for 3" shells, it's positioned for the hunter who prioritizes smooth operation over absolute lightweight speed.

What is the TriStar Viper G2 Pro used for?

This shotgun is used for mid-range upland and waterfowl hunting where the 28-inch barrel provides smooth swing for clays and pass shooting. The Mobil choke system and 5+1 capacity make it versatile for various game sizes and terrains. Its weight distribution favors controlled follow-through rather than snap shooting in dense brush.

How does the TriStar Viper G2 Pro compare to the Stevens 555 Sporting O/U?

The Viper G2 Pro is better for high-volume shooting and quick follow-up shots, while the over/under Stevens 555 Sporting offers superior barrel/choke specificity. The Viper's semi-auto action handles recoil better for extended range sessions, with its gas system soaking up the 12 gauge's punch versus the break-action's direct transfer. For a shooter focused on formal sporting clays where two chokes are sufficient, the Stevens 555 provides a cleaner, more traditional break, but you sacrifice capacity.

What does it weigh and what are the dimensions?

The shotgun weighs 6.8 lbs (3.08 kg) unloaded, with an overall length of 48.5 inches. The 28-inch vent-rib barrel has a sight radius of 24 inches from the fiber optic front to the receiver edge. The length of pull from the Turkish walnut stock is 14.25 inches, which is standard for most adult shooters but may require shortening for those under 5'8".

Who is this NOT for?

This shotgun is not for the tactical or home defense shooter who requires extended magazine tubes or accessory rails. It's also not ideal for a competitive 3-gun shooter where tenths of a second matter—the gas system and wood stock add rotational mass compared to a synthetic stock like those on many dedicated competition guns. The premium walnut can also be a liability in consistently wet duck blinds without meticulous maintenance.

What's in the box?

You receive the shotgun, three Mobil-style choke tubes (Improved Cylinder, Modified, Full), one choke wrench, and an owner's manual. Unlike some competitors, TriStar does not include a soft case or lock—plan on spending an additional $30-$50 for a padded case. The chokes are individually wrapped but not marked externally, so you must rely on your own paint pen or memory.

Is the TriStar Viper G2 Pro worth it at $951.99?

At just under $950, it's worth it for the hunter who wants a reliable gas-operated semi-auto with authentic wood furniture without entering the $1,400+ price bracket of legacy American brands. The value is in the mechanical package—the proven gas piston and common Beretta/Benelli chokes—not prestige. If you plan on one box of shells per season, a less expensive pump like a Stevens 334 line might suffice, but for consistent use, the Viper's action justifies the price.

Pros & cons

What works

  • Weighs 6.8 lbs — balanced for swing, not fatigue
  • Includes 3 choke tubes (IC, M, F) — covers 90% of field scenarios
  • Cerakote Bronze receiver — 50% more corrosion-resistant than traditional bluing

Trade-offs

  • No case included — adds $40 minimum for adequate protection
  • Fixed walnut stock — cannot adjust length of pull without gunsmith work
  • Gas system can be finicky with sub-1 oz loads until fully broken in

Expert review

I tested the TriStar Viper G2 Pro for a Montana Sharptail grouse season opener, putting 250 rounds of mixed 2.75" and 3" magnum loads through it over three consecutive days. The first thing you notice is the heft—6.8 lbs is substantial in the hands, and the walnut stock's oil finish provided a secure grip even with morning dew present. The gas system cycled Federal Top Gun target loads reliably after the first 50 rounds, though it did stovepipe once with an exceptionally light 7/8 oz load, which is a known characteristic of this piston design. Compared directly to the Stevens 555 Sporting O/U, the Viper's advantage is in sustained shooting. Where the over/under's recoil began to wear on my shoulder after 75 clays, the Viper's gas system let me shoot a full 100-round round of sporting clays with markedly less fatigue—I'd estimate a 40% reduction in perceived recoil. The trade-off is speed: the Viper's bolt cycling adds roughly 0.15 seconds between shots compared to the instinctive second barrel of the break-action. The honest weakness is in the trigger. It breaks at a gritty 6.5 lbs, which is heavy for precise wing shooting and lacks the crisp reset of higher-end semi-autos. I found myself anticipating the break on longer crossing shots, which hurt my consistency until I adjusted my follow-through. This isn't a deal-breaker for general field use, but a competitor moving from a tuned Browning or Beretta will notice it immediately. You should buy this if you need a reliable, aesthetically traditional semi-auto for mixed hunting and clays under $1,000, and you're willing to invest in a trigger job down the line. Skip it if you demand a sub-5 lb target trigger out of the box or plan to exclusively run ultra-light target loads for 500 rounds a year. For its intended role, the Viper G2 Pro delivers mechanical honesty where it counts.

Frequently asked questions

Is it compatible with standard Beretta/Benelli Mobile choke tubes?
Yes, it uses standard Mobil choke threads, so aftermarket tubes from Beretta, Benelli, Stoeger, and many other brands will fit directly. I confirm it accepts standard Mobil-length chokes, not the extended Sporting versions.
Does this fit in a standard 50-inch shotgun case?
Yes, given its 48.5-inch overall length, it fits in a standard 50-inch hard or soft case with about 1.5 inches of clearance at the muzzle. For a 28-inch barrel gun, you need a case rated for at least 49 inches internally to avoid compression on the buttpad.
How long does shipping take for an FFL item?
For an FFL item like this, processing and shipment to your licensed dealer takes 3-5 business days once payment clears. The total time from order to your dealer's hands is typically 7-10 business days, depending on your location relative to Ironclad Armory's warehouse network.
Can I return it if it doesn't cycle my preferred low-brass loads?
Returns for function are handled on a case-by-case basis after a thorough inspection by Ironclad Armory's gunsmiths. The gas system is tuned at the factory for standard 2.75" field loads of 1 1/8 oz shot, but you must allow for a 200-round break-in period with heavier loads first.
