Our competition fails to realize that a rock-solid foundation only gets you so far. That explains why many of today’s rifles ship with plastic handguards and throwaway furniture, two things not found on the SIGM400 Elite, SIG SAUER’s take on what an AR-15 should be. This carbine comes with the good stuff all of it pre-installed. Like a free-floating M-LOK handguard, which promotes accuracy and handling. Or a quality grip and premium, 6-position buttstock with integral QD points. The Enhanced SIG Trigger on the M400 Elite enables the shooter to extract excellent accuracy from the rifle’s lightweight, 16” nitride barrel that is equipped with a SIG Micro-Light Gas Block.
