SIG SAUER MCX Spear Features
Designed with versatility and operator control in mind, the MCX Spear features a Coyote anodized receiver and Magpul SL-M stock that folds and collapses for both portability and ergonomic customization. Its 16-inch barrel is threaded with a 5/8×24 pitch, compatible with suppressors and a variety of muzzle devices, and comes equipped with a SIG SLX/SLH QD flash hider to reduce signature and improve control.
The optic-ready upper receiver allows seamless integration of your preferred scope or red dot system, while the M-LOK handguard offers ample space for lights, grips, or lasers. The ambidextrous bolt and catch release enhance handling for left- or right-handed shooters, and the 1:7 twist rate is optimized for stabilizing heavier projectiles from the 6.8x51mm cartridge. Whether you’re in the field, on the range, or deploying in a defensive role, the MCX Spear delivers unmatched versatility and performance in a modern battle rifle package.
