SIG Sauer M400 - Guns For Sale

The SIG Sauer M400 is an AR-15-style rifle chambered in 5.56 NATO (.223 Remington compatible). Its 16-inch stainless steel barrel has a 1:7 twist rate, and the free-floating M-LOK handguard supports optics, lights, and grips without affecting barrel harmonics. The lightweight aluminum receiver balances durability and weight. Ambidextrous controls — safety selector and magazine release — accommodate left- and right-handed shooters. The polished trigger provides a consistent pull, and the 6-position collapsible stock adjusts for fit. A top Picatinny rail runs the length of the upper for optics mounting.
