Sig Sauer MCX Spear LT IR 300 BLK SBR 9" FDE

The MCX Spear LT IR: Purpose-Built Performance

Sig Sauer's MCX platform represents decades of refinement through extensive testing, innovation, and real-world feedback from professional operators. The MCX Spear LT IR builds on this proven foundation with cutting-edge technology and precision engineering.

Thermal Signature Reduction

The Gen II IR Cerakote finish in Flat Dark Earth reduces your thermal signature under night vision and thermal imaging—a capability that has earned the MCX platform adoption by Special Forces Groups worldwide. This specialized coating also provides superior wear and corrosion resistance, protecting your investment through demanding conditions.

Ergonomic Design for Serious Use

• Lightweight M-Lok handguard for accessory mounting and reduced overall weight
• Fully ambidextrous controls for left and right-handed shooters
• Tele-fold stock design for compact storage and transport without sacrificing cheek weld
• SIG Flatblade Match Trigger for predictable, clean breaks
• Rocksett QD suppressor-ready flash hider for quick-attach sound suppression

Versatile Platform

The MCX Spear LT IR ships in 300 Blackout—an ideal subsonic cartridge for suppressed fire. Interchangeable barrels allow you to adapt this rifle to your mission requirements. The 9" barrel length optimizes velocity while maintaining the compact profile that makes the MCX Spear LT IR equally at home in vehicles, tight spaces, or as a dedicated short-range precision tool.

This is a rifle built for operators who demand reliability, precision, and adaptability.
