SIG Sauer M400 Rose 556 5.56 NATO 16" 30-Round Threaded Barrel Carbine

The SIG Sauer M400 Rose 556 5.56 NATO 16" carbine is a modern sporting rifle purpose-built for tactical operators, competitive shooters, and home defense. With its 16-inch threaded barrel and 30-round magazine capacity, this semi-automatic platform delivers the reliability demanded by law enforcement and military professionals in field-tested conditions. The M400 Rose platform has earned its reputation as a dependable, accurate alternative to legacy direct-impingement systems, offering superior ergonomics and modularity for users who require precision performance without compromise.

This carbine features a 1/2x28 threaded muzzle, allowing integration of suppressors, flash hiders, or muzzle brakes to manage recoil and signature control in tactical scenarios. The Romeo5 red dot sight co-witnessed configuration provides dual-plane aiming capability—enabling both reflex and iron sight operation simultaneously for mission flexibility. The 5.56 NATO chamber maintains NATO compliance while delivering proven ballistic performance across intermediate distances, and the 30-round detachable magazine ensures adequate ammunition on-hand for extended engagements or training cycles without frequent reloads.

Operators requiring a compact yet powerful defensive carbine will appreciate the M400 Rose's 16-inch profile, which balances maneuverability in confined spaces with ballistic efficiency. Law enforcement units, private security contractors, and serious sport shooters benefit from the threaded barrel for sound and recoil management without sacrificing velocity. The integrated rail platform supports optic mounting, flashlights, and tactical accessories, making this rifle adaptable to evolving threat environments. Installation of muzzle devices or optics requires no gunsmithing—simply ensure suppressors or flash hiders are properly timed and seated to achieve optimal performance.
