Sig Sauer M400 Tread V2 | 5.56 NATO | 16″ | RM400-16B-TRD-V2G

The SIG SAUER M400 TREAD V2 is a modern sporting rifle built around a 16″ stainless steel barrel and an aluminum receiver with a Moss Green Cerakote finish. It ships optics-ready and pairs well with compact low-power variable optics; the Vortex Strike Eagle 1-6×24 is a practical choice under $1000 that complements this platform for close-to-medium range work. Typical uses include precision-oriented range training and varmint or small-game field work where a light, accurate 5.56 platform is preferred.

If you need a single, versatile AR-pattern rifle for training and field use that accepts common aftermarket optics and accessories, this configuration provides a solid starting point.
