The MCX platform has been SIG's breeding ground for the best rifle system through extensive testing and customer feedback. The MCX SPEAR LT is the latest evolution of the MCX platform. Based off the MCX Virtus, the MCX SPEAR LT utilizes a lightened handguard with added rigidity, lightened barrel profile with improved accuracy, ambidextrous bolt catch/release, coyote anodized finish and AR15 trigger compatibility.

The MCX SPEAR lineup also includes new calibers such as 7.62x39 while maintaining reliability and smooth shooting. The MCX SPEAR LT sets a new bar on modular weapons systems.
