The SIGM400 series rifle is designed for use in law enforcement, military operations, the sporting field, and competitive shooting, a true AR platform tactical rifle with unparalleled accuracy. A 16" Nitride-treated barrel provides superior corrosion resistance and a 7075-T6 aircraft grade aluminum forged lower receiver adds to the durability and reliability that users come to expect from Sig Sauer. The reliable direct impingement gas operating system uses a rotating locking bolt. The SWAT model has a two-piece aluminum quad rail. This semi-automatic rifle features adjustable back-up sights, a collapsible stock, and a 30-round magazine. Its stock, metal, and bore are all in very good condition.
