The STG-556 is a state-of-the-art, battle-proven bull pup rifle that brings you absolute function and reliability. Like all bull pup rifles, the STG uses the normally wasted space in the stock to store its action and magazine, creating a smaller rifle with a full-sized barrel. Each part of the STG is carefully manufactured, with close attention paid to fit and finish. The STG's gas operated rotating bolt and short piston drive won't jam up with repeated use. Its high-strength alloy receiver, chrome-lined barrel, and ergonomically designed polymer stock and fore-arm are all lightweight and incredibly durable. This semi-automatic rifle features a factory scope and includes a 30-round magazine and a 10-round magazine. Its synthetic stock, metal, and bore are all in very good condition.
