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

Built for builders who demand consistency across platforms, the Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) delivers two matched 80% platforms from a single trusted manufacturer. Each component is precision-molded in black polymer and requires standard finishing steps to become a functional firearm frame. This bundle eliminates the guesswork of sourcing separate kits and ensures material compatibility for both your AR15 rifle build and PF940C pistol frame project.

Overview

The Polymer80 RL556V3 – Rhino 80% AR15 Lower Receiver and PF940C 80% Pistol Frame (Black Only) is a factory-direct pair of unfinished frames. The RL556V3 Rhino lower receiver is compatible with standard mil-spec AR15 upper receivers and parts kits, while the PF940C frame accepts Glock 19 gen3-compatible slide and internal components. Both items are classified as 80% frames and require drilling, milling, and finishing before assembly. No serial number is present, and these frames are not considered firearms by the ATF at the time of purchase. This bundle is offered exclusively in black.
