Sig Sauer MCX SPEAR LT 5.56 NATO Pistol 11.5" Barrel - IR Cerakote

The SIG SAUER MCX‑SPEAR LT IR takes the proven SPEAR LT platform and enhances it with a Gen II NiR (Near‑Infrared) FDE Cerakote finish, engineered to reduce IR signature under night vision and thermal imaging. This specialized coating also provides superior wear and corrosion resistance, ensuring long‑term durability in harsh environments.

Featuring SIG’s Tele‑Fold design, a lightweight ergonomic handguard, fully ambidextrous controls, and a match‑grade flat‑blade trigger, the MCX‑SPEAR LT IR is built for professional‑grade reliability. Its gas‑piston operating system, cold hammer‑forged barrel, and suppressor‑ready QD flash hider make it a versatile, mission‑ready platform trusted by elite units worldwide.
