Sig Sauer MCX-SPEAR-LT .223/5.56 NATO 16" Barrel - Gen II NiR FDE Cerakote

The SIG Sauer MCX SPEAR‑LT represents the newest evolution of the legendary MCX platform—engineered through years of real‑world testing, user feedback, and continuous refinement. Chambered in 5.56 NATO with a 16" lightweight profile barrel, the SPEAR‑LT delivers exceptional accuracy, reduced recoil, and unmatched modularity in a battle‑proven design trusted by elite units worldwide.

Finished in Gen II NIR‑compliant Flat Dark Earth Cerakote, the SPEAR‑LT dramatically reduces IR signature while offering superior corrosion and wear resistance. The rifle features fully ambidextrous controls, a telescoping/folding stock with push‑button hinge, and a 13" free‑float M‑LOK handguard for maximum adaptability. The QD suppressor‑ready flash hider, flatblade match trigger, and compatibility with all MCX‑LT barrels and handguards make this rifle a true next‑generation modular weapon system.
