Lancer’s Carbon Fiber Handguard for the Sig Sauer MCX is a lightweight M-LOK compatible upgrade over the standard OEM handguard. The LCH-MCX installs easily – utilizing the OEM mounting hardware – while being approximately 40% lighter than the original factory handguard. Lancer’s carbon fiber handguards are also engineered for use over top of most standard suppressors and have a much lower rate of thermal conductivity than aluminum handguards.
