TriStar Viper Series G2 Silver semi-automatic shotguns are reliable, functional and hard-working. These gas-operated, wooden models feature polished a forend and pistol-grip stock with cut checkering and beautiful silver-finish receivers. This lightweight sub-gauge is built on a true frame and all the parts have been built to scale - including the stock, forearm, and receiver with a chrome-lined, 2.75" chamber. The vent-rib barrels are also chrome-lined and threaded for the 4 included Beretta-style choke tubes (IC, M, F, ExSk). A manual, five-round E-Z Load magazine cut-off allows for quick unloading and safety, and includes a shot plug. Shim kits are standard on all TriStar semi-auto models.
