SIG MCX Upper Receiver

Receivers · SIG Sauer

The SIG MCX upper receiver is a monolithic aluminum design that serves as the firearm's primary structural component. Unlike conventional AR-15 uppers, the MCX upper integrates the top rail, barrel mounting system, and recoil mechanism into a single, rigid assembly, enhancing durability and performance.
