Introducing | The Sig Sauer – SIGM400 Elite TI Rifle. The First M4 to Earn the SIG Name.

The First M4 to Earn the SIG Name. We didn’t set out to make just any M4. Instead, we used the innovation, performance and attention to detail that defines other SIG rifles to evolve the platform. The result is the SIGM400, a superior system offering advanced features available right out of the box that were once only found on the after-market.

Accurate, lightweight and crafted from the finest components and a titanium finish and optional ROMEO5 red dot sight, the SIGM400 Elite sets the new standard for direct-impingement AR-15s.

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 features Titanium Cerakote and ships 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. Further sweetening this ready-to-shoot package is an optional ROMEO5 red dot sight that features MOTAC (Motion Activated Illumination) and an insane 40,000-hour battery life.
