Lancer SIG MCX Carbon Fiber Handguard 10.5" M-LOK

The Lancer SIG MCX Carbon Fiber Handguard is a lightweight replacement forend engineered for the SIG MCX (Legacy Series) rifle platform. Built from carbon fiber composite, this handguard delivers approximately 40% weight savings compared to traditional aluminum forends while retaining excellent rigidity and a suppressor-rated thermal profile for use with muzzle devices that vent forward of the handguard.

The 10.5" handguard features M-LOK slots on the sides and top for mounting lights, lasers, vertical grips, and other accessories, and ships with an integrated 1.5" Picatinny rail extension across the top to preserve optics and back-up iron sight mounting options. At just 6 oz, the Lancer carbon fiber handguard trims front-end weight for faster handling and reduced shooter fatigue over long sessions.

Finished in black carbon fiber, the handguard installs using the factory mounting interface on the SIG MCX. This listing is for the 10.5" configuration only; 12" and 18" versions are also available for owners who want a longer forend with the same carbon fiber weight savings.
