This bundle pairs Polymer80’s reinforced RL556V3 lower receiver with their dedicated RL556v3 jig kit, giving you the essential tooling and receiver needed to complete your build at home. Whether you are a seasoned builder or stepping into your first 80 percent lower project, this kit is designed to deliver consistent results without unnecessary complexity. Overview Polymer80 is a well-known name in the firearms community, and the RL556V3 – Rhino 80% AR15 Lower Receiver and RL556v3 Jig Kit Bundle continues that reputation. The RL556V3 lower receiver features a reinforced polymer construction with an integrated trigger guard and a flared magazine well for easier reloads. It is an 80 percent lower, meaning it requires final machining using the included jig kit to complete the fire control cavity and trigger pin holes. The jig itself is a multi-piece system that clamps securely to the receiver, guiding your drill and router for accurate cuts. This bundle simplifies the process, so you can focus on the build instead of sourcing separate tooling. Features & Specs Reinforced polymer construction with integrated trigger guard and flared magazine well for improved ergonomics and reliability. Compatible with mil-spec AR15 lower parts kits, buffer tubes, and stocks, allowing for a fully customizable build. Includes the RL556v3 jig kit with hardened steel drill bushings and alignment pins for precise machining of the fire control pocket and pin holes. The receiver itself is designed to accept standard AR15 upper receivers and magazine catch assemblies. The jig kit includes step-by-step instructions and all necessary drill bits for common home workshop tools, so you can complete the lower without a full gunsmithing setup. The bundle is a complete package: you get the receiver and the jig in one box, ready to work. Who It Is For This bundle is ideal for the builder who wants a durable, lightweight lower receiver without the cost or lead time of a billet aluminum option. It is suited for DIY enthusiasts who have access to a drill press or a hand drill and a router, and who are comfortable following detailed machining instructions. The polymer80 rl556v3 – rhino 80% ar15 lower receiver and rl556v3 jig kit bundle is also a practical choice for those who prefer to keep their build within a specific budget, as the polymer receiver offers excellent value. It is not for someone looking for a complete, ready-to-fire rifle out of the box; it is for the hands-on builder who wants to learn the mechanics of the AR15 platform while creating a functional firearm. Shipping & FFL Because the RL556V3 lower receiver is an 80 percent finished item, it is not classified as a firearm under federal law and does not require transfer through a Federal Firearms License (FFL) dealer for shipment.
