Owners of the Viper G2 Pro in 28 gauge tend to pick it for upland bird hunting, and most find the 28-inch vent rib barrel well-balanced for that application. The light recoil of the 28 gauge in a semi-automatic platform is a frequent positive noted by newer or recoil-sensitive shooters.

The CT-4S choke inclusion is well-received; buyers appreciate having a useful spread of constrictions ready from the factory rather than paying extra. Fit and finish on the Select model is generally considered a step above the base Viper G2, though a portion of owners note the wood quality varies between individual units.

Value is a consistent theme in sentiment around the Viper G2 line. The Pro earns praise as an accessible entry into quality semi-automatic shotguns, but some owners who step up from it find the gas system less refined than European competitors at higher price points.
