Precision Upgrade for Polymer80 Double Stack Builds: NQI PFDS Rear Rail System
The NQI PFDS Rear Rail System (RRS) is designed for builders who demand superior strength, precision engineering, and long-term reliability in their double stack Polymer80 pistol frames, including all sub-compact, compact, and full-size platforms. This professional-grade upgrade transforms your build with military-spec performance characteristics.
Manufactured from premium American-sourced 17-4 stainless steel and precision CNC milled to exacting specifications, this rear rail system dramatically outperforms standard MIM or stamped components. The enhanced engineering and improved tolerances deliver measurable gains in accuracy, consistency, and overall fitment, making it an essential upgrade for competitive shooters and professionals who require absolute reliability from their firearms.
Unlike conventional heat-treated rails that accelerate wear on your slide components, this innovative RRS features a purposefully non-heat-treated design that allows the rail itself to wear instead of your more expensive slide. This intelligent engineering approach significantly extends the service life of your entire firearm while maintaining smoother long-term operation and more consistent performance shot after shot.
For builders seeking ultimate precision, some final honing can be performed to achieve a perfectly flat rail surface from front to rear, though this advanced fitting is optional for most applications. Those pursuing competition-level refinement can consult our comprehensive manuals section for detailed technical guidance, professional installation tips, and step-by-step video walkthroughs to optimize their build.

🛠 Fitment & Installation Notes
- Some precise final fitment or light gunsmithing may be required depending on your specific drilled holes and lower parts kit (LPK) components to achieve optimal performance.
- Always verify complete 100% engagement between your striker lug and trigger bar during installation and testing to ensure safe, reliable operation.
- For professional-grade results, an armorer’s back plate is strongly recommended to properly assist with critical inspection and precision fitting procedures.
- We highly recommend watching our detailed support videos for best practices, professional techniques, and important safety considerations before beginning your installation.
