Our Absolute Hit – Learn MoreThe M400-TREAD V2 extends the legacy of one of SIG SAUER’s most popular modern sporting rifles, bringing upgraded features directly inspired by user feedback. Built to raise the bar on performance and value, the V2 models feature an enhanced free-floating handguard for improved control and accessory mounting, along with the crisp SIG Matchlite 2-stage trigger for cleaner breaks and better accuracy.
Each of the M400-TREAD V2 models retains original design features, including a 16” stainless steel barrel along with a reliable mid-length gas system for smooth operation and reduced recoil. Additional standard features include an ambidextrous safety and magazine release, plus integrated QD mounts on the lower receiver.
The stainless-steel barrel on the M400-TREAD V2 is fitted with a 3-prong flash hider and has a versatile 1:8 twist rate. For personal adjustments and a comfortable fit, the TREAD V2 comes equipped with a MAGPUL SL-K telescoping stock.
