Engineered to fit the Sig Sauer MPX, Lancer’s 8″ Carbon Fiber Lightweight M-LOK Handguard is a drop-in replacement that offers a 50% weight reduction over the original factory unit. The carbon fiber tube is quickly installed or removed for cleaning using the OEM takedown pin. It features Magpul M-LOK attachment slots along its length for compatibility with tactical aftermarket accessories, and with an inside diameter of 1.6″ it is compatible with most sound suppressors.
