The TriStar Viper Max 12 Gauge (TriStar part no. 24182) is a gas-operated semi-auto shotgun built to handle everything from light target loads to heavy 3.5-inch magnum waterfowl shells. Its two-piston system swaps between a light load piston for 2.75-inch shells and a heavy load piston for magnum loads, so one gun covers the dove field and the duck blind. The 28-inch barrel wears a chrome-lined bore and a vented rib for fast target acquisition, and the durable injection-molded synthetic stock shrugs off wet, muddy hunts. Backed by a five-year mechanical warranty, it is built for hunters who need one shotgun that adapts to the load in hand.

Key Specifications

• Chambered for 2.75-inch and 3.5-inch 12 gauge shells thanks to the swappable two-piston operating system.
• The 28-inch barrel is chrome-lined and vented-rib for durability and a clean, fast sighting plane.
• A fiber optic front sight sits atop the rib for quick target acquisition in low light.
• The 5-round tubular magazine loads from the bottom and includes a removable shot plug for capacity flexibility.
• A magazine cut-off button near the trigger guard lets the shooter unload the chamber without cycling a fresh shell from the magazine.
• Four Beretta/Benelli-pattern MobilChoke tubes (Skeet, Improved Cylinder, Modified, Full) ship with a choke box and wrench for quick pattern changes.
• The stock and forearm are injection-molded synthetic with a rubber recoil pad to tame heavy magnum loads.
