Sig MCX SPEAR LT 5.56 11.5" FDE Pistol

Product Description

The SIG MCX-SPEAR LT IR is a compact, piston-driven 5.56 NATO pistol engineered for professional end users operating in demanding environments. Built around SIG’s proven MCX architecture, this 11.5" platform integrates advanced materials, signature-reducing finishes, and fully ambidextrous controls to deliver reliability, adaptability, and refined handling in a lightweight package.

Finished in Gen II NiR Flat Dark Earth Cerakote, the SPEAR LT IR is designed to reduce infrared signature while maintaining durability in harsh conditions. The short-stroke gas piston system ensures consistent cycling with reduced fouling, supporting reliable performance across a wide range of operating conditions.

The platform features fully ambidextrous controls, including the safety selector, charging handle, and magazine release, allowing seamless operation from either side. A lightweight M-LOK handguard provides modularity for mission-specific accessories, while the SIG Flat-Blade Match trigger delivers a clean, consistent break for enhanced control and accuracy.

A SIG Tele-fold brace offers both compact storage and adjustable support, and the factory-installed Rocksett® SIG QD flash hider is suppressor-ready with standard 1/2×28 threads. The system also supports interchangeable barrels, increasing long-term versatility for end users.
