Sig Sauer, M400 Tread V2 Ca, 223 Rem 5.56 NATO, 16 inch, 10+1, Magpul Moe

The SIG RM40016BTRDV2CA M400-TREAD-V2 CA from SIG Sauer is a California-compliant iteration of the M400 series that gives shooters a full-featured, semi-auto 5.56 NATO rifle engineered for hunting, range work, and duty use while meeting state regulations; chambered in .223 Rem/5.56 NATO with a 16" stainless steel barrel and 1:8" twist, the rifle delivers reliable accuracy and stabilization for common range loads and varmint or small-game hunting, and the threaded barrel with a 3-port muzzle brake helps control recoil and muzzle rise for faster follow-up shots. The mid-length direct impingement gas system smooths cycling and softens felt recoil compared to carbine-length systems, and the free-floating Tread enhanced M-LOK handguard offers a stable platform for optics and accessories without affecting barrel harmonics. The SIG 2-stage Matchlite DUO trigger improves shot control for precision strings, while the Magpul MOE fixed carbine stock, CA-compliant grip, ambidextrous safety and magazine release, integrated QD sling mount, and 10+1 capacity create a user-friendly package for right- or left-handed shooters. As a rifle that requires FFL transfer, this M400-TREAD-V2 CA blends the M400 series� proven reliability with California-legal features for responsible owners seeking a compliant semi-auto rifle.
