The Truth About the SIG MCX From a Guy Who Built It
This video details the development of the SIG MCX, featuring insights from Adam Agri, who was instrumental in its creation. It covers the evolution from early concepts like the Curge and LVAW programs, the challenges faced with the AR-15 platform (like cam path wear and charging handle issues), and the design decisions that led to the MCX's unique short-stroke piston system and dual buffer design to mitigate bolt bounce. The discussion highlights the extensive testing and iterative improvements made over four years, culminating in the production MCX.
