Sig M400 VTAC 5.56 Rifle With 16" Barrel, 13" Free Float Aluminum MLOK Handgun & Sig ROMEO 5 Optic . Ships With 1-30 Round Magazine. RM400-16B-VTAC-SI. Factory equipped with a ROMEO 5 red dot optic with 2 MOA reticle.

The 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 VTAC rifle. 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 VTAC free-floating 13" M-LOK aluminum handguard, which promotes accuracy and handling. Or a top quality grip and premium, Magpul SL-K multi position buttstock. The Sig trigger on the M400 enables the shooter to extract excellent accuracy from its 16” nitride barrel that is equipped with a SIG Gas Block.
