Sig Sauer MCX Virtus 300 Blackout Pistol w/ PCB Brace - 9" CHF Barrel - Concrete Gray

Built for mission-critical performance and engineered with second-generation durability, the Sig Sauer MCX Virtus Pistol in .300 Blackout is a powerhouse in a compact, concealable package. Conceived for the demands of the Special Operations community, the Virtus platform delivers unmatched modularity, rugged construction, and precision accuracy. Its 9" cold hammer-forged barrel, Matchlite Duo trigger, and internal recoil system work together to reduce recoil and enhance control—making it ideal for suppressed or unsuppressed operation.

Compared to the newer Spear LT, the MCX Virtus maintains a heavier, more rigid profile for enhanced stability and long-term durability. With a free-floating M-LOK handguard, ambidextrous AR-style controls, and a foldable Pivoting Contour Brace (PCB), this pistol is ready to adapt to any environment. Finished in Concrete Gray and built with premium materials, the MCX Virtus sets the standard for tactical versatility.
