SIG SAUER MCX-LTAW PISTOL 300 BLACKOUT

The SIG SAUER MCX-LTAW Pistol is an ultra-compact .300 Blackout platform designed for maneuverability, suppressor-focused performance, and reliability. Built around SIG SAUER’s proven MCX operating system, the MCX-LTAW combines a 6.75-inch cold hammer-forged barrel, a suppressor-compliant handguard, and fully ambidextrous controls in a compact, performance-driven package.

Inspired by the LVAW platform, the suppressor-compliant handguard features an integrated full-length heat shield for improved heat management and a streamlined profile. The gas-piston operating system and 1:5 twist rate complement the pistol’s .300 BLK configuration, while the two-stage Match Duo trigger provides a consistent trigger pull.

The MCX-LTAW includes a folding pistol brace with push-button unlock, an MCX Legacy angled polymer pistol grip, and a 30-round Gen3 Magpul magazine. Finished in black anodizing, this compact SIG SAUER pistol brings modern MCX design and premium construction together.
