Sig Sauer 2401191R MCX Picatinny Stock Adapter Kit - Aluminum

The Sig Sauer 2401191R Picatinny Stock Adapter Kit is a factory accessory built specifically for the Sig MCX rifle platform. This adapter gives MCX owners the ability to install Sig MCX folding stock assemblies, including collapsible stocks and pistol stabilizing braces designed for the platform.

Machined from lightweight aluminum and finished in black, the unit serves as the factory hinge assembly that mates a folding or collapsible stock to the MCX receiver's Picatinny interface. Its low-profile geometry keeps the rifle compact and balanced while providing a secure, factory-spec mounting point for stabilizing accessories.

Whether you are configuring a new MCX build or replacing a worn factory hinge, this Sig Sauer stock adapter delivers the precise fit and function expected from factory original components.
