The M400 is SIG SAUER's AR-15, and the Forge is the model that makes the line accessible without cutting the parts that matter. It uses a forged aluminum upper and lower, a 16-inch barrel with a mid-length gas system for a smoother impulse and longer part life, and a free-floating M-LOK handguard.

Chambered for 5.56 NATO and .223 Remington with a black finish, it is a straightforward, dependable duty and defense carbine from a manufacturer with a serious military and law enforcement track record.
