The SIG Sauer MCX Spear-LT IR 5.56 NATO Pistol brings premium, combat-tested short-stroke gas piston technology into a highly adaptable 11.5-inch large-format pistol layout. Built upon the battle-proven architecture of the MCX series, this premium platform utilizes a specialized Gen II NIR Flat Dark Earth Cerakote finish that drastically reduces your signature profile under night vision or thermal observation systems. The highly rigid, lightweight aluminum M-LOK handguard is integrated into the receiver using advanced screw anchoring to safeguard your top-rail alignment across heavy operational use. Handling is seamless under intense pressure thanks to fully ambidextrous operations—including the magazine release, slide catch, charging handle, and safety levers—paired with a crisp SIG Flatblade Match two-stage trigger. Equipped with an 11.5-inch cold hammer-forged barrel, a bufferless push-button folding pistol brace, and a factory-mounted Rocksett SIG QD suppressor-ready flash hider, this low-profile 30-round package delivers supreme flexibility and tight tracking for close-quarters maneuvers and tactical deployment.
