Purpose-Built Performance

Chambered in 5.56 NATO, the M400 Tread V2 features a 16-inch stainless steel barrel with a free-floating M-LOK handguard, enhancing both accuracy and modularity.

Ambidextrous controls make operation intuitive for both right- and left-handed shooters, while the upgraded flat-blade trigger offers a crisp, clean break to improve shot consistency.

Modular by Design

Outfitted with a full-length Picatinny top rail and M-LOK handguard, the Tread V2 is ready for mission-specific attachments—optics, lights, lasers, and more. It’s compatible with the full line of Tread-branded accessories, allowing you to build out your rifle exactly how you want it—no compromises.
