Design highlights and core features

The SIG SAUER M400-TREAD V2 extends the M400 lineage with an engraved, enhanced free-floating M-LOK handguard for improved accessory mounting and better barrel harmonics. It keeps a 16″ stainless steel barrel with a 1:8 twist rate and a 3-prong flash hider for consistent muzzle control. The mid-length gas system smooths recoil impulse compared to carbine-length setups, and the six-position MAGPUL SL-K telescoping stock provides a familiar, lightweight interface for pointability.

Trigger, controls, and receiver upgrades

This V2 ships with the SIG 2-Stage Matchlite Duo trigger, a crisp Matchlite feel that helps shooters break shots cleaner and tighten groups. Ambidextrous safety and magazine release controls make the platform accessible for both hands, while integrated QD mounts on the lower receiver expand sling options for duty or range carry.

Performance and practical applications

The 1:8 twist rate accommodates a broad range of projectile weights, including heavier match bullets commonly used in 5.56/.223-style platforms, improving stability for precision work. The mid-length gas system reduces felt recoil and cyclic harshness, which helps follow-up shots and sustained strings during training. Color options—Black Anodized, Moss Green Cerakote, and Concrete Cerakote—let owners match mission or range preferences while maintaining the same baseline performance.

Accessories and customization potential

The free-floating M-LOK handguard and QD mounts make it easy to add optics, back-up sights, lights, and slings without modifying the rifle’s balance. The Matchlite trigger and stainless barrel are solid foundations for shooters who plan to upgrade optics or mounts for specific roles, whether competitive precision, home defense, or a dedicated range rifle.

Buying considerations

At a retail price of $1001.99, the SIG SAUER M400-TREAD V2 positions itself as a value-focused rifle that carries meaningful factory upgrades. The Sig Sauer name signals a legacy of quality and aftermarket support, and the V2’s feature set—match trigger, free-floating handguard, mid-length gas system, ambidextrous controls, and QD-ready lower—makes it a strong choice for shooters who want an out-of-the-box performer.
