Key Features
- Free-Floating M-LOK Handguard — Keeps barrel harmonics clean for consistent shot placement. Mount lights, bipods, or slings without messing with zero.
- Stainless Steel Barrel — Resists rust and holds up to heavy strings of fire at the range or on the ranch. Expect sub-MOA accuracy with quality ammo.
- Ambidextrous Controls — Safety selector and magazine release are mirrored for lefties or off-hand drills. No fumbling when speed counts.
- Optics-Ready Receiver — Flat-top upper with Picatinny rail, no iron sights included. Mount your preferred red dot, LPVO, or prism scope instantly.

Who It’s For
Ranchers, rural workers, and utility shooters who need a rifle that works in the truck, on the fence line, or at the steel range. If you’re tired of finicky guns that need constant tuning, this TREAD V2 is built to run dry, run dirty, and run long. The Moss Green finish blends into brush and pasture without screaming “tactical.”
Pros & Cons
- Pro: Accuracy out of the box — tested with 77-grain OTM, shot consistent 0.9 MOA groups at 100 yards.
- Pro: Light enough for all-day carry, heavy enough to soak up recoil.
- Con: Factory trigger feels gritty — many shooters swap it for a Geissele or Timney drop-in. Plan on a trigger upgrade if you want a crisp break.

FAQ
Does the SIG SAUER M400 TREAD V2 come with iron sights?
No. The upper receiver is optics-ready with a Picatinny rail. You’ll need to add your own red dot, scope, or backup irons.
Is this rifle legal to own in all 50 states?
It ships with a 30-round magazine. Some states restrict magazine capacity — check your local laws. The rifle itself is compliant in most states, but California, New York, and a few others have specific feature restrictions.
Can I swap the handguard for a different one?
Yes. The barrel nut is standard AR-15 pattern, so any M-LOK or KeyMod handguard designed for a standard nut will fit. The factory handguard is easy to remove with a standard armorer’s wrench.
What kind of accuracy should I expect?
With match-grade ammunition (like 77-grain SMK), expect 0.8–1.0 MOA. With bulk 55-grain FMJ, expect 1.5–2.0 MOA. The stainless barrel is capable, but the mil-spec trigger limits precision.
