Split Rail Upgrade Kit for Polymer80™ PF940v2 Full-Size Frame

Experience a new level of ease and precision when building your Polymer80™ with the Split Rail Upgrade Kit. This patent-protected system revolutionizes the P80 build process by allowing each rail to independently align with the frame and trigger components. We’ve eliminated the hardest part of the build — simply drop in your lower parts kit and hammer in your pins for a smooth, successful installation every time.

As industry leaders in the 80% market, we’ve engineered our rails with a connector clearance cutout to eliminate the “mush” that often plagues other rear rail systems. This ensures your trigger maintains a crisp, consistent feel without the need for filing, grinding, or additional tuning.

Machined from premium stainless steel billet, these rails are a significant upgrade from traditional MIM or stamped components. Tightened dimensional tolerances provide an exceptionally precise slide-to-rail fit, improving function, reliability, and overall performance. When it comes to enhancing the fitment and function of your PF940v2 frame, there’s no better value.

Key Features

• Easy Drop-In Installation: Split rail design simplifies alignment and ensures a successful build the first time.
• Optimized Trigger Performance: Connector clearance cutout prevents interference for a smooth, consistent trigger pull.
• Precision Machined: CNC tolerances exceed the tightest MIM or stamping processes for perfect fit and function.
• Premium Stainless Steel: Billet construction provides exceptional durability and strength you can rely on.
• Improved Fitment: Tightened tolerances ensure superior slide-to-rail engagement for enhanced reliability.

Compatibility

Compatible with Polymer80™ PF940v2 (Full-Size) frames.

Details

These rails are precision-engineered for builders who want the best possible fit, finish, and performance from their Polymer80™ frame. The innovative split rail design improves ease of installation while ensuring a rock-solid connection between the slide and frame. With US Patent No. 12,031,791, this system represents the most advanced rail upgrade available for the PF940v2 platform.

Note: This product is designed specifically for the Polymer80™ PF940v2 full-size frame. Rails for the PF940C compact frame are available separately.
