Featuring a 16-inch cold hammer forged steel barrel with an FNC finish, this platform is designed for long-term wear resistance and consistent precision. The mid-length gas system helps manage recoil for a smoother shooting experience, keeping the rifle stable and on target during rapid follow-up shots. A 15-inch M-LOK handguard with a full-length Picatinny rail provides a lightweight and modular interface for mounting optics and accessories.

Engineered for refined control, the rifle is equipped with a TriggerTech 3.5-pound two-stage flat blade duty trigger, offering a clean and predictable break. The 6-position Magpul SL-K stock allows for adjustable fit and improved ergonomics, while the ambidextrous charging handle supports versatile operation. Finished in Moss Green Cerakote, the M400 Forge combines rugged construction with a modern feature set, making it well-suited for range use, training, and field applications.
