The SIG Sauer MCX Spear LT (Lite) brings the revolutionary MCX platform to a wider audience in both 5.56 NATO and .300 Blackout. Featuring the MCX's signature gas-piston operating system, folding stock capability, and quick-change barrel system, the Spear LT delivers next-generation modularity.
The IR (Improved Rifle) variant features enhanced ergonomics and finishes. Available in pistol (11.5" barrel) and rifle (16" barrel) configurations with 30+1 capacity. The MCX platform eliminates the need for a buffer tube, enabling a true folding stock that reduces overall length dramatically for transport and storage.
