Technical Specifications
Why Choose the Sig M400 Tread V2 Pistol
The Sig M400 Tread V2 Pistol offers the perfect balance between power and portability. The 11.5-inch barrel retains excellent velocity for 5.56 ammunition while keeping the overall length short enough for tight spaces. This makes it ideal for home defense and vehicle carry.
Unlike many AR pistols on the market, the Tread V2 comes with genuine Sig Sauer quality. Every component is engineered to exacting standards. The mid-length gas system provides a smoother recoil impulse than carbine-length systems. The magnetic bolt catch prevents the bolt from closing on an empty magazine, a thoughtful touch for reload drills.
The SB Tactical stabilizing brace is included, not an afterthought. It is adjustable and provides a stable platform for accurate shooting. The M-LOK handguard is free-floating, which improves accuracy by eliminating pressure on the barrel. For the price, you get features usually found on much more expensive firearms.
Performance and Design
The Tread V2 uses a direct impingement gas system with a mid-length gas tube. This setup reduces felt recoil and carrier bounce compared to carbine-length systems. The 11.5-inch chrome-lined barrel is durable and accurate. The 1:7 twist rate stabilizes both light and heavy 5.56 bullets effectively.
The flat-faced trigger provides a consistent, predictable pull at 6-7 pounds. The break is clean, and reset is short and tactile. The ambidextrous safety selector works for both left and right-handed shooters. The SB Tactical brace is adjustable for length of pull and can be folded for storage.
The M-LOK handguard is free-floating and features multiple attachment points for lights, lasers, and grips. The magnetic bolt catch is a Sig exclusive feature that holds the bolt open when the magazine is empty. The pistol also includes a Picatinny rail on the receiver for optics. The overall design is clean, functional, and battle-ready.
