The TriStar Viper Max is a 12 gauge, gas-operated semi-automatic field shotgun built for hunting and sporting use, especially waterfowl and field work where varying load power is common. Its dual-piston system supports both light target loads and heavy waterfowl loads, and the package includes multiple MobilChoke tubes for patterning versatility. The overall specification and factory features make it a practical choice for shooters who need a ready-to-use, purpose-built field shotgun.
