The SIG Sauer M400 SDI is a semi automatic rifle chambered in 5.56 NATO with a 16 inch barrel and a 30 round magazine, finished in black. Its Magpul SL stock and 33.25 to 36.50 inch overall length let shooters set the rifle to their preferred fit, while the included ROMEO5 Gen II optic and FOXTROT-MSR light put a sighting solution and a light on the gun from the start.

Built on the AR-15 platform with a 30+1 capacity, the M400 SDI suits target and practice shooting. The package arrives with one 30 round magazine, the ROMEO5 Gen II optic, and the FOXTROT-MSR light, so the rifle is ready to set up for the range.
