The M400 Sentry offers a ready-to-go solution, combining the M400-SDI X platform with the multi-purpose functionality of the ROMEO5 GENII red dot and the Foxtrot-MSR Full Size Light. The M400-Sentry is furnished with a vertical foregrip on the free-floating handguard, enabling greater control of the rifle regardless the shooting position. The ROMEO5 GENII red dot with its 1x aiming solution and crisp 2 MOA dot, provides over 40,000 hours of estimated runtime compliments of SIG SAUER's motion-activated MOTAC design. The ROMEO5 GENII is IPX7 waterproof rated, and its fully-multicoated lenses ensure visibility in all environments. Top mount illumination controls provide ease of use by both left and right-handed shooters. The Foxtrot-MSR full size light with its 1,250 Lumens and 33,000 Candela, clearly illuminates targets while maintaining ease of use and accessibility. Includes three M-LOK rail covers and a 30rd polymer magazine.
