Sig Sauer M400 Tread V2 5.56 NATO 16" Rifle

Sig Sauer M400 Tread V2: Modern Rifle Design Done Right

The M400 Tread V2 represents Sig Sauer's commitment to delivering a modern sporting rifle that balances performance, reliability, and user-friendly features. This is a rifle built for shooters who demand accuracy and control without unnecessary complexity.

Barrel and Accuracy

The 16-inch stainless steel barrel offers genuine durability and corrosion resistance—practical advantages for shooters in varied environments. The 1:8 twist rate provides versatility across a wide range of 5.56 NATO ammunition weights. A 3-prong flash hider manages muzzle signature while keeping the rifle compact for practical use.

Ergonomics and Control

Ambidextrous safety ensures both right and left-handed shooters operate the rifle intuitively. The lower receiver features integrated QD mounts for quick sling attachment, a feature that matters when you're actually using the rifle in the field.

Trigger and Handling

The SIG Matchlite 2-stage trigger delivers the kind of predictable break that improves accuracy and control. This is a trigger designed for shooters who care about precision.

Handguard and Accessories

The free-floating M-LOK enhanced handguard is lightweight yet rigid—a combination that matters when mounting lights, lasers, or other accessories. M-LOK slots provide secure, repeatable mounting without the bulk of older systems.

Stock and Gas System

The Magpul SL-K telescoping stock allows quick adjustment for different shooting positions and gear configurations. The mid-length gas system delivers smoother operation and reduced recoil compared to carbine-length systems.

The Bottom Line

The M400 Tread V2 is a no-compromise rifle for shooters who understand that quality matters. It delivers the features serious shooters need without the marketing hype.
