SIG SAUER’s MCX platform has established itself through rigorous testing, continuous refinement, and input from users. The MCX-SPEAR LT builds on the proven MCX Virtus design with a lightened handguard featuring attachment screws for added rigidity and a lightened profile barrel engineered for improved accuracy. The lower receiver incorporates an ambidextrous bolt catch and release, while the rifle wears a coyote anodized finish. The minimalist stock enables maximum compact foldability, and the trigger system maintains AR15 style compatibility.
This 16 inch semi-auto rifle in 7.62x39mm represents an important expansion of the MCX family into this caliber. The MCX-SPEAR LT incorporates a new latch system specifically developed to reliably cycle the variety of 7.62 caliber ammunition available while delivering consistent performance and smooth operation.
