Polymer80 P80-JIG-RL556v3 Jig Kit

The Polymer80 P80-JIG-RL556v3 Jig Kit is a precision-engineered tooling system designed for the assembly of AR-15 style lower receivers. This jig kit provides the structural alignment and drilling guidance necessary to complete a Polymer80 80% lower receiver. Manufactured by Polymer80, a recognized leader in the firearms components industry, this kit belongs to the Build Kits category and serves as a critical component for the firearm builder seeking a reliable, repeatable machining process. The P80-JIG-RL556v3 Jig Kit is the third iteration of this platform, incorporating refinements to improve alignment accuracy and ease of use during the pocketing and pin installation stages. This kit is not a firearm and does not contain any serialized components; it is a tool intended for use with a compatible 80% lower receiver.

Overview

The Polymer80 P80-JIG-RL556v3 Jig Kit provides the physical template required to complete the machining of an AR-15 80% lower receiver. This jig kit is the dedicated tooling for the Polymer80 PF940v3 and PF940C frames, ensuring correct alignment for the trigger pocket, fire control group pocket, and pin holes. The design of this jig kit prioritizes repeatability and dimensional accuracy, reducing the margin for error during the drilling and routing process. The P80-JIG-RL556v3 Jig Kit includes the main jig body, drill bushings, and alignment pins necessary to complete the build process. This kit is a mandatory tool for anyone assembling a Polymer80 PF940v3 or PF940C lower receiver; without it, the critical machining steps cannot be performed to the manufacturer’s specified tolerances.

Features & Specs

This jig kit is constructed from impact-resistant polymer and features hardened steel drill bushings at critical alignment points. The v3 iteration includes improved indexing features to secure the lower receiver firmly during machining. The kit is compatible with standard drill presses and hand drills, requiring no special tooling beyond common workshop equipment. The P80-JIG-RL556v3 Jig Kit is designed for use with Polymer80 PF940v3 and PF940C frames exclusively; it is not compatible with other 80% lower receiver brands or models. The kit dimensions are optimized for bench-top operation, with a compact footprint that allows for stable clamping in a vise.

• Hardened steel drill bushings at trigger pin, hammer pin, and safety selector locations
• Impact-resistant polymer jig body with reinforced pocketing channel
• Includes alignment pins, drill bit guide, and pocketing template insert
• Compatible with Polymer80 PF940v3 and PF940C 80% lower receivers

Who It Is For

The Polymer80 P80-JIG-RL556v3 Jig Kit is intended for the intermediate to advanced firearm builder who possesses a basic understanding of drilling and routing operations. This kit is suitable for individuals who are committed to completing a Polymer80 PF940v3 or PF940C lower receiver and require the specific tooling to do so. It is not a starter kit for those unfamiliar with power tools or firearm assembly procedures.
