Polymer80 P80-JIG-RL556v3 Jig Kit

The polymer80 p80-jig-rl556v3 jig kit is the essential tooling component for completing your Polymer80 80% lower receiver build. Designed specifically for the RL556v3 platform, this jig kit provides the precise alignment and guide paths required to correctly mill and drill your lower receiver. As a standalone kit, it allows you to repurpose a jig from a previous build or complete a lower that did not ship with tooling. This is a direct OEM product from Polymer80, ensuring exact tolerances and fitment for the RL556v3 frame.

Overview

This polymer80 p80-jig-rl556v3 jig kit includes all the necessary components to fixture and guide your tooling through the critical machining steps. The kit functions as a rigid clamping system that holds your 80% lower in place while providing hardened steel drill bushings and routing templates. It is engineered for use with a standard drill press and hand router, eliminating the need for expensive CNC equipment. Whether you are completing a first build or need a replacement jig, this kit delivers repeatable, professional-grade results.

Features & Specs

• Precision-machined polymer jig body with hardened steel drill bushings for accurate pin and trigger pocket placement.
• Includes 4x alignment pins, 2x drill bits, 1x end mill, and a hex wrench set for complete tooling support.
• Compatible exclusively with the Polymer80 RL556v3 80% lower receiver; not interchangeable with other frame generations.

The polymer80 p80-jig-rl556v3 jig kit weighs approximately 1.2 pounds and measures 10 x 6 x 2 inches. The jig body is constructed from impact-resistant ABS polymer, while the drill bushings are hardened tool steel rated for repeated use. All components are manufactured in the United States to Polymer80’s specification standards.

Who It’s For

This jig kit is intended for DIY firearms builders who possess basic mechanical skills and access to a drill press and router. It is ideal for hobbyists constructing a single AR-15 style pistol or rifle from an 80% lower receiver. The polymer80 p80-jig-rl556v3 jig kit is also suitable for gunsmiths who require a dedicated jig for the RL556v3 platform without purchasing a complete build kit. This product is not for those seeking a completed firearm; it is a tooling component only and requires user fabrication to finish the lower receiver.

• Ideal for first-time builders using a drill press and hand router.
• Serves as a replacement or spare jig for existing RL556v3 builds.
• Designed for the specific geometry of the RL556v3 frame; verify your lower is this generation before purchase.
