MCX LT Spear (FDE)

The Sig Sauer MCX SPEAR-LT represents the latest evolution of the MCX platform, combining the battle-proven short-stroke gas piston operating system with a lighter handguard, refined barrel profile, and fully ambidextrous controls in a single package. Available in FDE (Coyote Tan) finish, this configuration is built around a 5.56x45mm NATO chamber with a cold hammer-forged, nitrided barrel and the SIG Flat-Blade Match trigger as a factory-standard component rather than an upgrade. The folding telescoping stock and short overall length make the MCX SPEAR-LT one of the most versatile and capable modern sporting rifles in its class.

The third-generation MCX SPEAR-LT introduced in 2022 brought a redesigned handguard with additional attachment screws for improved rigidity, a new barrel profile for enhanced accuracy, and an updated QD suppressor-ready muzzle device. The platform is designed from the ground up for suppressor use, with the piston system eliminating the backpressure issues that plague direct-impingement designs when cans are added. For shooters who want a premium, piston-driven modern sporting rifle in a compact, adaptable package with the backing of Sig Sauer's military development program, the MCX SPEAR-LT delivers.
