SIG SAUER MCX-LTAW SBR 300 BLACKOUT

The SIG SAUER MCX-LTAW SBR is an ultra-compact .300 Blackout platform designed for maneuverability, compact storage, and proven MCX reliability. Featuring a 6.75-inch cold hammer-forged carbon steel barrel with a factory-installed training tube, this short-barreled rifle combines a compact footprint with the performance-focused design of the SIG SAUER MCX platform.

Inspired by the LVAW platform, the suppressor-compliant handguard features an integrated full-length heat shield to help manage heat while maintaining a streamlined profile. Fully ambidextrous MCX LT controls provide convenient operation for right- and left-handed shooters, while the two-stage Match Duo trigger delivers a crisp, predictable break.

The MCX-LTAW SBR features a folding skeletonized KM stock with push-button unlock for compact storage and a stable shooting platform. Additional features include a gas-piston operating system, MCX Legacy angled polymer pistol grip, M-LOK forend, and a black anodized finish. The package includes one 30-round Gen3 Magpul .300 BLK magazine.
