Let’s Talk About SIG SAUER Mcx/mpx Stock Hinge Assembly – 1913
The SIG SAUER Mcx/mpx Stock Hinge Assembly – 1913 is a seemingly simple component, but it’s the key to unlocking greater versatility in two of SIG SAUER’s most popular platforms. This factory replacement part allows you to attach any 1913-compatible stock or brace to your MCX or MPX, transforming a fixed platform into a compact, folding package. Its purpose is clear: enhance portability and adaptability without sacrificing the core performance of your firearm.
I had always been frustrated by the lack of compactness of my MCX when stored or transported in confined spaces. The standard stock protruded, limiting my options for discreet carry and adding bulk to my tactical gear.

Compared to aftermarket hinges I’ve seen, this SIG SAUER part felt much more durable and precisely manufactured. I chose this over cheaper, universal adapters due to my faith in SIG SAUER’s engineering and a desire for guaranteed compatibility.
My first impression was one of cautious optimism. The assembly appeared robust and well-made, but the true test would be in the installation and actual field use. I was excited about the potential for enhanced portability, but also concerned about potential wobble or compromise in the platform’s stability.
