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

This bundle delivers two foundational platforms for the builder seeking a matched set of 80% components. The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) provides the core material for completing both a precision AR-15 build and a compact pistol frame, all from a single trusted manufacturer. Both components are constructed from high-impact, glass-reinforced polymer, designed to withstand rigorous use while maintaining dimensional accuracy. This is a complete starting point for two independent firearm projects, offered exclusively in black.

Overview

The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) combines two of the most popular 80% platforms on the market. The RL556V3 Rhino lower receiver is engineered for compatibility with standard AR-15 mil-spec upper receivers and parts kits, offering a reinforced front takedown pin boss and an integrated trigger guard. The PF940C pistol frame is designed for compact 9mm Glock-compatible slides and magazines, featuring a reduced grip angle and an aggressive texture pattern. Both components require standard finishing work, including drilling and milling, to become functional receivers.

Features & Specs

This bundle is built around proven Polymer80 engineering, focusing on structural integrity and ease of completion. The RL556V3 Rhino lower receiver includes a patented front pin system that eliminates the need for roll pin installation, while the PF940C frame incorporates a universal rail system for holster compatibility. Both components are made from the same durable Nylon 6/6 composite used throughout the Polymer80 product line.

• RL556V3 Rhino 80% AR15 lower receiver: reinforced front takedown pin boss, integrated trigger guard, Mil-spec buffer tube compatibility, and a textured grip surface.
• PF940C 80% pistol frame: compact frame size for 9mm builds, accepts Glock 19/23/32 gen 3 slide and barrel, standard Glock magazine compatibility, and an aggressive stippled grip texture.
• Both units: 100% American-sourced materials, black color finish, and require standard machining tools for completion.

Who It’s For
