The Viper Max is a gas-operated, semi-automatic shotgun engineered for versatility, handling everything from light target loads to heavy waterfowl loads with ease, thanks to its innovative two-piston system. The secondary piston is conveniently stored in the forearm for quick access. This model includes four BerettaA(R)/BenelliA(R) Mobil chokes (SK, IC, M, F) and features over-molded rubber grips on the stock and forearm, providing enhanced comfort and control.
