Description

The SIG SAUER MCX-SPEAR LT IR 300 BLK 9" SBR represents the next evolution of the MCX platform, delivering advanced performance, modularity, and reduced signature capability in a compact, suppressor-ready system. Built on the legacy of the MCX Virtus, the SPEAR LT incorporates cutting-edge engineering and real-world feedback to create a highly adaptable and reliable rifle.

Finished in SIG’s Gen II IR Cerakote in Flat Dark Earth, this model is designed to reduce visibility under thermal and night vision devices while providing superior corrosion and wear resistance. The lightweight M-LOK® handguard and fully ambidextrous controls enhance handling and versatility across a wide range of applications.

Chambered in .300 Blackout with a 9" barrel and 1:5 twist rate, the MCX-SPEAR LT is optimized for both suppressed and unsuppressed performance. The gas piston operating system, paired with an adjustable gas system, ensures reliable cycling and reduced fouling. A Rocksett® SIG QD suppressor-ready flash hider makes it ready for modern suppressor setups.

Equipped with a SIG flat blade match trigger, folding minimalist stock, and AR-pattern magazine compatibility, the SPEAR LT delivers precision, control, and adaptability in a compact SBR platform.

Backed by the SIG SAUER Infinite Guarantee™, this rifle is built for long-term performance without compromise.
