Billet-Machined Carbon Fiber M-LOK Components
Moruzzi’s billet-machined carbon fiber M-LOK rail covers and handstops are engineered for lightweight performance builds. Designed for AR-15 and AR-10 platforms using standard M-LOK slot spacing, our components deliver precision fit, structural rigidity, and a clean low-profile aesthetic.
Unlike injection-molded polymer alternatives, Moruzzi’s components are machined from monolithic carbon fiber plate. This construction method ensures consistent lug geometry, minimal flex under recoil, and secure engagement on standard M-LOK handguards.
Available in multiple slot configurations, our rail covers and handstops are built for serious builders who prioritize strength-to-weight performance and material integrity.
For detailed compatibility information, see our M-LOK Fitment Guide.
Why Carbon Fiber?
Carbon fiber delivers exceptional strength-to-weight performance compared to injection-molded polymer alternatives. Moruzzi components are machined from monolithic carbon fiber plate for structural rigidity, consistent lug geometry, and lightweight durability under recoil.
