Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only)

Overview

The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) represents a comprehensive build platform for the discerning hobbyist and professional gunsmith. This kit delivers two distinct unfinished receivers: the RL556V3 Rhino for AR15 pattern rifles and the PF940C for compact 9mm pistols. Both components are precision-molded from high-impact polymer and require final machining to complete. As an 80% product, neither receiver is classified as a firearm under federal law, allowing for direct shipment to your door without an FFL transfer. The black finish is uniform across both frames, providing a cohesive aesthetic for matched builds.

Features & Specs

The polymer80 rl556v3 – rhino 80% ar15 lower receiver and pf940c 80% pistol frame (black only) incorporates specific engineering choices to streamline the finishing process. The RL556V3 Rhino lower features a reinforced buffer tower, integrated trigger guard, and a flared magazine well for rapid reloads. The PF940C frame utilizes a full-length steel rail system embedded in the polymer, ensuring dimensional stability during the milling process. Both components are manufactured from proprietary Polymer80 Nylon 6/6 blend, offering high impact resistance and UV stability.

• RL556V3 Rhino Lower: Accepts standard AR15 upper receivers, LPK, and buffer tubes. Pre-indexed jig pin locations for precise drilling. Compatible with mil-spec trigger groups and pistol grips.
• PF940C Frame: Designed for Glock 19 Gen3 slide and barrel assemblies. Includes a locking block rail system pre-installed. Features an extended beavertail and textured grip panels.
• Kit Contents: One RL556V3 80% lower receiver, one PF940C 80% pistol frame, both in black. All necessary polymer material for finishing is intact. No jigs, bits, or tooling included.

Who It’s For

This dual-frame kit is intended for individuals with access to a drill press, router, or milling machine who possess the technical skill to complete the final machining operations. The polymer80 rl556v3 – rhino 80% ar15 lower receiver and pf940c 80% pistol frame (black only) suits builders who want a matched set of 80% frames for simultaneous projects. It is ideal for those familiar with AR15 and Glock platform tolerances, as both receivers require precise pocketing for fire control groups and trigger housings. Not recommended for first-time 80% builders due to the complexity of the PF940C rail system installation.

• Experienced hobbyists building a custom AR15 and a compact pistol simultaneously.
• Gunsmiths seeking a consistent polymer platform for test builds or customer projects.
• Individuals who prefer to complete their own receivers to avoid FFL transfer fees and paperwork.
