Polymer80 P80-JIG-RL556v3 Jig Kit

The Polymer80 P80-JIG-RL556v3 Jig Kit is a precision-engineered tooling solution for builders who demand accuracy and repeatability in their AR-15 lower receiver projects. This jig kit, produced by Polymer80, is the definitive guide for completing a serialized or non-serialized 80% lower with clean, aligned pockets and correctly drilled pin holes. Designed for use with the RL556v3 frame, this kit streamlines the milling and drilling process, reducing the margin for error and delivering professional-grade results. For any builder serious about assembling a reliable firearm from a raw lower, the polymer80 p80-jig-rl556v3 jig kit is the correct choice.

Overview

The Polymer80 P80-JIG-RL556v3 Jig Kit is a purpose-built fixture system that locks your 80% lower into a rigid, repeatable alignment. Unlike universal jigs, this kit is specifically designed to match the exact geometry of the RL556v3 frame, ensuring that every cut and drill point corresponds perfectly to the manufacturer’s specifications. The kit includes hardened steel drill bushings, a multi-position clamping system, and a clear acrylic guide plate that allows visual verification of your work. Whether you are completing a single lower or planning multiple builds, this jig kit provides the durability and precision needed for consistent results. The polymer80 p80-jig-rl556v3 jig kit is fully compatible with standard router bits and drill bits, making it a straightforward addition to any workshop.

Features & Specs

This jig kit delivers a complete solution for machining the fire control pocket, trigger pin holes, hammer pin holes, and safety selector hole. Every component is manufactured to tight tolerances to eliminate slop and ensure that your completed lower will accept mil-spec trigger groups without modification.

• Precision-machined aluminum and polymer construction for long-term durability and resistance to wear.
• Hardened steel drill bushings for pin holes, ensuring clean, round holes that prevent trigger pin walk.
• Clear acrylic top plate with marked cut lines for visual reference during the milling process.

Key specifications of the polymer80 p80-jig-rl556v3 jig kit include compatibility exclusively with the Polymer80 RL556v3 frame. The kit weighs approximately 2.5 pounds and includes all necessary hardware for assembly. No additional jig components are required to complete a standard build. The kit is designed for use with a standard hand router or drill press, though a router is recommended for optimal control of the fire control pocket depth.

• Designed specifically for the Polymer80 RL556v3 80% lower receiver.
• Includes drill bushings for trigger, hammer, and safety selector pin holes.
• Durable clamp system holds lower securely during all machining operations.

Who It’s For

The polymer80 p80-jig-rl556v3 jig kit is intended for experienced firearm builders and hobbyists who have a working knowledge of power tools and lower receiver assembly. This kit is not a beginner-level product; it requires the user to possess a router or drill press, appropriate safety equipment, and the ability to follow detailed instructions. It is best suited for individuals who have previously completed a polymer 80% lower or similar project and understand the importance of patience and precision during machining. If you are a competent DIY builder looking for a jig that matches the exact specifications of your RL556v3 frame, this kit will save you time and reduce material waste. This product is sold as a tooling kit and does not include a firearm frame or receiver.
