Sig Sauer MCX SPEAR .277 Fury (6.8X51mm) SBR 13" Barrel - 20 Rd

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 6.8x51 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 6.8x51, 7.62x51, 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.
