Sig Sauer MCX 5.56 NATO 16" Bbl Semi Fold Stock AL MLOK HG Blk Rifle/(1) 30rd Mag RMCX-556N-16B-LT-B

The SIG Sauer MCX‑SPEAR LT is the latest evolution of the MCX family — a lightweight, highly modular 5.56 NATO carbine built for durability, accuracy, and user configurability. The 16″ lightened profile barrel (1:7 twist) rides under a long ergonomic M‑LOK handguard and terminates in a SIG Clutch‑Lok / QD suppressor‑ready flash hider with 1/2‑28 muzzle threads, while the short‑stroke piston system and two‑position gas regulator promote reliable function in adverse conditions. Fully ambidextrous controls, a flat‑blade match trigger, and a folding/telescoping stock make the MCX‑SPEAR LT comfortable and intuitive for a wide range of shooters, and it ships with a single 30‑round AR‑pattern magazine for 30+1 capacity. Available in black or coyote/FDE finishes, the MCX‑SPEAR LT blends premium fit‑and‑finish with military‑grade features for operators, competitors, and serious enthusiasts alike
