The SIG SAUER M400-FORGE is a modern 5.56 NATO rifle engineered for shooters who demand reliability, precision, and performance. Built around a 16" cold hammer forged barrel and mid-length gas system, the M400-FORGE delivers exceptional durability and smooth, consistent operation in any environment.
Upgraded where it matters. Ready from day one.
At the heart of the rifle is a TriggerTech 3.5 lb two-stage flat blade duty trigger, delivering the kind of crisp, predictable break shooters typically upgrade to. Paired with the included ROMEO-MSR Gen II red dot optic, the M400-FORGE provides fast target acquisition and confident shooting right out of the box.
A full-length free-floating M-LOK handguard, ambidextrous charging handle, and MAGPUL SL-K adjustable stock deliver modern ergonomics and adaptability for a wide range of applications.
Built by SIG SAUER, a brand trusted worldwide for performance and durability, the M400-FORGE is backed by the SIG Infinite Guarantee—our lifetime, fully transferable promise that stands behind every firearm we build.
The result is a rifle ready for the range, defense, and the mission ahead.
