Lancer SIG MCX 12" M-LOK Carbon Fiber Handguard

The Lancer SIG MCX 12" M-LOK Carbon Fiber Handguard is a lightweight upgrade for the SIG Sauer MCX platform, crafted from carbon fiber to significantly reduce weight over the factory handguard while adding modern accessory compatibility. The matte black finish matches factory SIG MCX furniture for a clean, integrated look.

Measuring 12 inches in length with a 1.8" internal diameter that allows for over-suppressor use, this handguard weighs just 0.75 lbs, making it roughly 40% lighter than the OEM handguard it replaces. It is designed as a direct replacement for the factory MCX handguard on the Legacy Series MCX.

M-LOK compatible accessory slots span the top, sides, and bottom of the handguard for clamping on lights, lasers, foregrips, and other accessories. A continuous 1.5" top Picatinny rail section allows direct mounting of red dots, magnified optics, and backup iron sights.

Lancer's MCX carbon fiber handguard is available in 10.5", 12", and 18" lengths, making it easy to match the handguard to your specific MCX barrel configuration. This 12" model is the ideal balance of weight savings, accessory real estate, and suppressor clearance for a Legacy Series MCX build.
