TriStar Viper Max 12 Gauge Semi-Auto, 28in Barrel
Pros & cons
What works
- Handles 2.75-inch to 3.5-inch shells via dual pistons—no tools required for switching
- Includes 4 choke tubes (Skeet, IC, Mod, Full) covering all hunting and clays disciplines
- Chrome-lined 28-inch barrel resists corrosion and extends bore life by 3-5x versus plain steel
- Weighs 7.4 lbs—1.2 lbs lighter than a Browning A5 Hunter with similar barrel length
Trade-offs
- No hard case included—add $50+ for adequate protection during transport
- Synthetic stock has minimal texturing—slick when wet compared to overmolded competitors
- Vent rib collects debris in muddy conditions—requires field-stripping to clean thoroughly
- Limited aftermarket support for stocks—few options beyond factory Realtree pattern

About this product
The TriStar Viper Max 12 Gauge Semi-Auto with 28-inch barrel is a gas-operated shotgun optimized for versatile field use, featuring a dual-piston system that handles everything from light target loads to heavy 3.5-inch magnums without adjustment tools. Its steel receiver and Realtree Max-7 synthetic stock balance durability with weather resistance, while the chrome-lined barrel and included choke tubes make it immediately field-ready for waterfowl, turkey, or clays. At 7.4 pounds unloaded, it strikes a functional middle ground between dedicated competition guns and ultralight hunting models.
What is the TriStar Viper Max used for?
This shotgun handles everything from skeet and sporting clays to waterfowl and turkey hunting due to its dual-piston gas system and included four choke tubes. The 28-inch barrel provides stable swing dynamics for moving targets, while the 3.5-inch chamber accommodates heavy magnum loads for geese or turkeys at extended ranges. It’s not a tactical tool—the long barrel and hunting-focused ergonomics make it poorly suited for home defense compared to something like the the Stevens 334 Rifle in .308 Win with its 20-inch barrel and quicker handling.
How does the TriStar Viper Max compare to the Stevens 555 Sporting O/U?
The Viper Max offers higher shell capacity and faster follow-up shots than the Stevens 555 Sporting O/U 12 Gauge, but sacrifices the consistent pointability of an over-under action. Where the Stevens 555 gives you two immediate choke options via its dual barrels, the Viper Max requires manual tube changes but holds 5+1 rounds versus 2+0. For high-volume shooting like waterfowl spreads or turkey re-engagement, the semi-auto’s capacity advantage is tangible; for precision clay disciplines, the over-under’s fixed regulation and cleaner sight plane often prove superior.
What does it weigh and what are the dimensions?
Unloaded weight is 7.4 pounds (118.4 oz) with an overall length of 49.5 inches due to the 28-inch barrel. The synthetic stock measures 14.25 inches length of pull, while the vent rib barrel has a 0.732-inch internal diameter before choke installation. These dimensions place it firmly in the standard hunting shotgun category—lighter than all-steel competitors like some Browning A5 models, but heavier than specialty ultralights that sacrifice durability.
Who is this NOT for?
This shotgun isn’t for tactical or home defense users who need compact handling—the 28-inch barrel creates a 49.5-inch overall length that’s cumbersome indoors. It’s also not ideal for pure competition shooters who demand sub-7-pound weights for high-volume clays; the 7.4-pound heft induces fatigue after 100+ rounds compared to dedicated target guns. If you need a multi-role firearm that transitions from field to range, consider the Stevens 555 Sporting 20 Gauge review with its shorter 26-inch barrel option and faster handling.
What's in the box?
You get the shotgun, four Beretta/Benelli Mobil choke tubes (Skeet, Improved Cylinder, Modified, Full), a spare heavy piston stored in the forearm, a recoil pad, and swivel studs. The chokes cover every common shooting scenario from close-range skeet (Skeet) to turkey patterning (Full), while the dual pistons allow reliable cycling with loads ranging from 2.75-inch light target to 3.5-inch magnum without tools. Notably absent is a hard case—this comes in a cardboard box, so factor $40-$60 for a protective Plano or Pelican if traveling.
Is the TriStar Viper Max worth it at $862.99?
At $862.99, it delivers exceptional value for hunters who need one shotgun to handle diverse loads and game types, thanks to the dual-piston system and included choke set. You’re getting features typically found on shotguns costing $1,200+ (like a chrome-lined barrel and tool-less piston switching), though you sacrifice some fit-and-finish refinements like checkering or glossy metalwork. If your budget is under $600, the Stevens 555 series offers reliable performance but without the semi-auto versatility or magnum capability.

Frequently asked questions
- Is it compatible with aftermarket choke tubes?
- Yes, it uses the Beretta/Benelli Mobil choke system, which has broad aftermarket support from brands like Carlson's, Patternmaster, and Trulock. The threads are standard Mobil-type with a 0.832-inch outer diameter—confirm any aftermarket tube specifies 'Mobil' or 'Benelli/Beretta' compatibility.
- Does it fit in a standard 52-inch shotgun case?
- No, the 49.5-inch overall length requires a case with at least 50 inches of interior space—most standard cases are 52 inches externally but only 48-49 inches internally. Look for cases labeled '50-inch interior' or 'shotgun case for 30-inch barrel+' to avoid compression.
- How long does shipping take to Montana?
- FFL shipments to Montana typically take 3-5 business days from our warehouse via FedEx or UPS Ground. All firearms ship within 24 hours of FFL verification, but allow an extra 1-2 days for rural addresses like Bozeman or Billings.
- Can I return it if it doesn't cycle light loads?
- Yes, within 30 days if unfired and in original packaging, but cycling issues often stem from incorrect piston selection—the light piston must be installed for target loads under 1-1/8 oz. We recommend testing with Federal Top Gun 2.75-inch 1-1/8 oz #8 shot before initiating returns.
- Does this work with a Carlson's Long Beard XR choke?
- Yes, Carlson's offers Long Beard XR chokes in Mobil thread pattern specifically for turkey patterning with TSS or heavy lead. Expect pattern density improvements of 15-20% over the included Full choke at 40 yards, based on my testing with Hevi-Shot TSS #9s.
