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

This bundle combines two of the most popular platforms for completing your own build at home. The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) provides a solid foundation for both a precision rifle and a reliable compact pistol. Both components are manufactured by Polymer80 to exacting tolerances, requiring only basic shop tools and a few hours of work to finish. The black finish is consistent across both frames, making for a clean, professional look without the need for additional coating.

Overview

The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) is a matched set designed for builders who want to produce two fully functional firearms from one purchase. The AR15 lower is compatible with standard mil-spec upper receivers and parts kits, while the PF940C frame accepts Glock 19 gen3 components. Both are machined from reinforced polymer with stainless steel trigger guard inserts and locking block rails pre-installed. The RL556V3 Rhino features an integrated trigger guard and a flared magwell for faster reloads. The PF940C includes a textured grip frame and a rail system for lights or lasers. This bundle eliminates the need to source separate frames for your rifle and pistol projects.

Who It’s For

This bundle is intended for experienced hobbyists and first-time builders alike who want to complete two firearms from one order. It is ideal for anyone who values hands-on assembly and wants to avoid the markup of fully assembled receivers. The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) is suited for shooters who prefer to customize their grip, trigger, and magazine release selections without being locked into a factory configuration. It is not for those seeking a drop-in, ready-to-fire product. You should have basic mechanical ability and access to a drill press or hand drill, a vise, and a set of precision pin punches. This kit is also appropriate for gunsmiths looking to add custom builds to their portfolio.

Shipping & FFL

Because both items are 80% receivers, they are not considered firearms by the ATF and can be shipped directly to your doorstep without an FFL transfer. No background check is required at the time of purchase. However, once you complete the frames, you are responsible for complying with all federal, state, and local laws regarding serialization, registration, and transfer. Check your local jurisdiction before ordering, as some states and municipalities restrict or prohibit the possession of 80% frames. By purchasing this product, you acknowledge that you are not prohibited from owning firearms and that you will complete the frames in compliance with applicable law. We do not provide legal advice. Shipping is via UPS Ground or FedEx Ground to all US states where these items are legal.
