Key Features
- Gas-operated action – WHY IT MATTERS: It tames recoil and cycles light target loads reliably, so you stay on target for the second shot on a double.
- 30-inch vent-rib barrel with matted sight plane – WHY IT MATTERS: The matted plane cuts glare and the fiber-optic front bead gives you a fast, clear point of aim on crossing clays.
- Removable choke system (Beretta/Benelli Mobil-style threads) – WHY IT MATTERS: You get a wide selection of aftermarket tubes and the included extended chokes let you change patterns quickly without a tool.
- Includes shot plug, choke wrench, and multiple extended choke tubes – WHY IT MATTERS: Everything you need for regulated shooting and easy choke changes comes right in the box, saving you a trip to the store.
- Full-size sporting stock with a shim-adjustable comb – WHY IT MATTERS: You can dial in the fit for your face and shooting style, which means better pointability and more hits on the range or in the field.
Who It’s For
This shotgun is for the Southern shooter who splits his weekends between the sporting clays course and the dove field. It’s a natural fit for the man who wants a reliable gas gun that won’t beat him up over a long day of shooting, but still swings fast enough for a flushing quail or a crossing mallard. If you’re a hunter who also shoots registered skeet or trap, the Viper G2 Pro Sport pulls double duty without breaking the bank.
Pros & Cons
- Pro: Cycles 1-ounce target loads reliably after a quick break-in.
- Pro: Extended choke tubes make pattern changes fast and easy.
- Pro: Gas system cuts felt recoil noticeably compared to inertia guns.
- Con: The factory trigger has a bit of creep before the break; a trigger job or aftermarket spring can clean it up if you’re a stickler.

FAQ
What loads does the TriStar Viper G2 Pro Sport cycle reliably?
After a short break-in (about 50 rounds of 1-1/8 oz target loads), it cycles 1-oz and 7/8-oz target loads, as well as field loads up to 3-inch magnums. Per TriStar specs, it handles 2-3/4 and 3-inch shells without issue.
Can I use aftermarket choke tubes with this shotgun?
Yes. The Viper G2 Pro Sport uses Beretta/Benelli Mobil-style threads, so any standard Mobil-choke tube from brands like Carlson’s or Briley will fit. The included extended tubes are also Mobil-pattern.
Does the shotgun come with a shim kit for adjusting drop and cast?
Yes, the stock includes a shim-adjustable comb. You can adjust the comb height to fine-tune your fit, and the buttstock can be shimmed for drop and cast using the included spacers.
Is this shotgun suitable for left-handed shooters?
The Viper G2 Pro Sport is a right-handed model with a right-side ejection port and crossbolt safety. Left-handed shooters can use it, but the shell ejects away from the face. TriStar also offers a left-handed version if you prefer.
