Polymer80 P80-JIG-RL556v3 Jig Kit

If you are building your own AR-15 lower receiver from a Polymer80 frame, the polymer80 p80-jig-rl556v3 jig kit is the specific tooling you need to get the job done right. This isn’t a generic drill template—it is the exact jig designed by Polymer80 to match their RL556v3 receiver geometry. Whether you are a first-time builder or a seasoned tinkerer, having the correct jig kit makes the difference between a clean build and a frustrating afternoon. We stock this kit because it works, and it works consistently.

Overview

The polymer80 p80-jig-rl556v3 jig kit is the official drilling and milling guide for Polymer80’s RL556v3 lower receiver. It comes as a complete kit with all the alignment blocks, drill bits, and pins you need to finish the receiver at home. No second-guessing the fit, no clamping improvisations—just drop the receiver into the jig and follow the process. This kit is the same one Polymer80 ships with their complete build sets, and we sell it separately for builders who bought a bare receiver or need a replacement jig.

Features & Specs

The jig kit is built from high-impact polymer and machined steel components. It holds the RL556v3 receiver rigidly in place while you drill the trigger pin holes, safety selector hole, and hammer pin hole. It also guides the router or drill for the fire control pocket. Every alignment block is color-coded to match the included instruction sheet.

• Precision-machined alignment blocks for trigger, hammer, and safety selector pin holes
• Includes hardened steel drill bits sized specifically for the RL556v3 receiver
• Reusable for multiple builds—clean it up and use it again on your next lower

This polymer80 p80-jig-rl556v3 jig kit also includes a rear pocket drilling template and a front takedown pin alignment tool. The jig body itself is reinforced at all stress points so it holds up to repeated use. If you already own a drill press or a hand drill, this kit gives you everything else you need to complete the machining process.

Who It’s For

This jig kit is for anyone who owns or plans to buy a Polymer80 RL556v3 lower receiver. It is especially useful if you are building your first AR-15 from a 80% lower and want a tool that removes the guesswork. The jig works with standard hand tools, so you do not need a CNC machine or a bridgeport to finish the job. It is also a practical choice for experienced builders who want a dedicated jig for the RL556v3 platform rather than using a universal template that might shift during drilling.

• First-time AR-15 builders who want a guided, repeatable process
• Experienced hobbyists adding the RL556v3 to their build rotation
• Anyone replacing a lost or worn jig from a previous kit

The polymer80 p80-jig-rl556v3 jig kit is also a solid option if you plan to build multiple RL556v3 receivers over time. The jig holds up to repeated clamping and drilling without losing alignment. Just keep the drill bits sharp and wipe down the jig after each use.
