A groundbreaking platform born from the U.S. Army’s Next Generation Squad Weapon (NGSW) program. Built to exceed modern battlefield demands, the MCX-SPEAR delivers next-level power, durability, and modularity—now available to civilian shooters.

Chambered in the advanced 6.8×51 hybrid cartridge, this rifle platform is capable of achieving velocities exceeding 3000 FPS (with a 16” configuration), offering exceptional ballistic performance and extended effective range. The MCX-SPEAR isn’t just powerful—it’s adaptable. With multi-caliber capability and interchangeable barrel lengths, you can configure your rifle for 6.8×51, 7.62×51, or 6.5 Creedmoor depending on your mission.

Designed for total control, the rifle features fully ambidextrous controls, a non-reciprocating side charging handle, and a rear charging handle for maximum operational flexibility. The 2-stage Matchlite Duo trigger delivers precision and consistency, while the free-floating M-LOK handguard and adjustable gas system ensure optimal performance across suppressed and unsuppressed setups.

Finished with a folding Magpul SL-M stock and a QD flash hider, the MCX-SPEAR blends cutting-edge military innovation with civilian-ready versatility—making it one of the most advanced rifle platforms available today.
