The RI 9MP Modular Pistol Build Kit gives you full control over your serialized firearm assembly—without compromise. This is a complete, precision-engineered kit manufactured entirely in-house by Redacted Industries, featuring everything you need to build a fully functional RI 9MP pistol platform.

From the custom upper and RI 9MP bolt to the serialized lower, grip module, rear configuration, hardware, and internals—every component is included and built to our standards of durability, modularity, and real-world performance.
