Polymer80 P80-JIG-RL556v3 Jig Kit

If you are building an AR-15 from an 80% lower, the Polymer80 P80-JIG-RL556v3 Jig Kit is the tool you need to finish the job right. This jig is designed to work with the Polymer80 80% lower receiver, guiding your drill and router so you can complete the fire control group pocket and trigger pin holes with confidence. It is a straightforward, no-nonsense kit for anyone who wants to assemble their own rifle at home.

Overview

The Polymer80 P80-JIG-RL556v3 Jig Kit is the third-generation jig from Polymer80, specifically built for their RL556v3 80% lower. It replaces older jig designs with a more rigid aluminum frame and improved alignment pins, which means less slop and cleaner cuts. This kit includes the jig body, drill bushings, end mill bushing, and all necessary hardware to complete your lower receiver. Whether you are a first-time builder or a seasoned hobbyist, this jig provides a reliable, repeatable setup for finishing your lower.

Features and Specs

• Durable aluminum jig body with hardened steel drill bushings for precise hole placement
• Compatible exclusively with the Polymer80 RL556v3 80% lower receiver
• Includes an end mill bushing for use with a router or drill press to cut the trigger pocket
• Pre-drilled alignment holes and locating pins to keep your lower locked in place during machining
• Compact design that fits in a standard vise or clamp setup

This kit is built to handle multiple builds. The bushings are replaceable, and the aluminum frame resists warping or flexing, so you get the same results every time. There is no guesswork involved: clamp the jig to your lower, follow the included instructions, and you will have a functional fire control group cavity ready for assembly.

Who It Is For

The Polymer80 P80-JIG-RL556v3 Jig Kit is for anyone who wants to complete an 80% lower without sending it off to a gunsmith. It is especially useful for home builders who prefer a dedicated jig over a universal setup. If you already own a drill and a router or a drill press, this jig will work with standard tools you likely have in your shop. It is also a good choice for those who want a repeatable process for building multiple lowers, since the jig holds the same position each time you use it. This kit is not for someone using a different brand of lower; it is designed exclusively for the Polymer80 RL556v3, so make sure your lower matches before purchasing.
