SIG SAUER M400 TREAD V2 (SAVIOR MSR II TACPAC)

The SIG Sauer M400 TREAD V2 (UPC 798681704606) is the definitive evolution of the modern sporting rifle, offering premium features without the premium price tag. While the original Tread set the standard for entry-level excellence, the V2 takes performance further with a significant upgrade: a newly designed free-float M-LOK handguard that is significantly lighter and more ergonomic. This AR-15 is chambered in 5.56 NATO and is built for shooters who want a high-performance rifle that is ready for customization right out of the box.

One of the most frequent questions from buyers is about the trigger; the M400 TREAD V2 comes standard with a single-stage polished hard-coat trigger, providing a much cleaner break than standard "mil-spec" options. The 16-inch stainless steel barrel offers superior corrosion resistance and accuracy, while the mid-length gas system ensures a smoother recoil impulse and reduced wear on internal parts. Additionally, the rifle features fully ambidextrous controls, including the safety selector and magazine release, making it an ideal choice for both left- and right-handed shooters.
