P80 Jig and Tool Kit: Precision Tools for Polymer80 Builds
This complete jig and tool kit streamlines the process of milling Polymer80 frames with professional results. Designed for builders who prioritize clean cuts and proper alignment, it includes all essentials to complete an 80% lower without guesswork. The hardened steel jig withstands repeated use, while the included drill bits and end mill are sized specifically for Polymer80’s tolerances. Over 745 units sold to date.

- Compatibility: Polymer80 PF940v2, PF940C, PF940SC frames
- Weight: 2.8 lbs (complete kit with packaging)
- Packaging: Reusable plastic case with foam insert
Feature Breakdown
The jig’s CNC-machined steel construction ensures consistent rail and pin hole alignment across multiple builds. Unlike aluminum jigs that wear over time, this unit maintains tight tolerances even after repeated use. The included end mill features a 1/4″ shank compatible with most routers and drill presses, while the cobalt drill bits resist heat buildup during prolonged use.
Pre-drilled starter holes eliminate the need for center punching, reducing setup time and potential errors. The jig’s modular design allows for sequential milling steps without repositioning the frame unnecessarily. All critical contact surfaces are ground flat to within 0.002″ for uniform pressure distribution during machining.
Tool selection focuses on practicality: the 3mm bit handles trigger and pin holes, while the 4mm bit prepares the rear rail cavity. Hex wrenches included match common frame screws to prevent stripping. The end mill’s flute geometry clears polymer chips efficiently, reducing heat that could warp the frame during cutting.
The reusable case organizes tools between builds and protects the jig’s alignment surfaces from damage. Foam inserts prevent shifting during transport, and the compact footprint fits in most range bags or workshop drawers. Total kit weight balances portability with the heft needed for stable milling operations.
Compatibility Notes
This kit is optimized for Polymer80’s PF940 series frames (full-size, compact, and subcompact). It will not function with aftermarket frames using proprietary rail systems or non-standard hole patterns. The jig accommodates both Gen3 and Gen4 slide configurations when used with Polymer80’s recommended parts kits.
Installation Overview
Secure the jig to a stable work surface using clamps before inserting the frame. Follow the numbered drill guide markings for sequential hole drilling, applying steady pressure without forcing the bits. Use the end mill for rail channel work in three passes: initial clearance, secondary depth, and final smoothing. Always wear eye protection and work in a well-ventilated area when machining polymer materials.
Frequently Asked Questions
Q: Does this work with drill presses?
A: Yes, the tools are compatible with standard benchtop drill presses. Use a medium speed setting (1,200-1,500 RPM) and secure the jig firmly.
Q: How many frames can one jig complete?
A: The steel construction typically lasts for 15-20 builds before alignment surfaces show measurable wear.
Q: Are replacement bits available?
A: Individual components can be sourced separately; refer to product documentation for specifications.
Q: Will this work on colored Polymer80 frames?
A: Yes, the jig functions identically regardless of frame color or finish.
Q: What’s the return policy?
A: Unused kits in original packaging may be returned within 30 days. See warranty terms for tool wear exceptions.
Warranty and Shipping
The jig carries a 1-year warranty against manufacturing defects. Tools are consumable items not covered by warranty. Ships via USPS Priority or UPS Ground from Manhattan, KS (allow 2-3 business days processing). Signature required for delivery.
