This kit delivers two of the most sought-after platforms in the 80% market: the RL556V3 Rhino AR15 lower receiver and the PF940C compact pistol frame. Both components are manufactured by Polymer80 to strict material and dimensional standards. The black-only finish is uniform across both frames, ensuring a cohesive build. Whether you are starting a new AR15 project or completing a compact handgun, this pairing offers a reliable foundation without unnecessary complexity.

Overview

Polymer80 has established a reputation for producing frames that require final machining by the end user. The RL556V3 Rhino is the third-generation AR15 lower, designed with an integrated trigger guard and a reinforced rear takedown boss. The PF940C is a compact 80% pistol frame compatible with Gen3 internal parts. Both items in this bundle are sold as unfinished, meaning they require drilling and routing to become functional receivers. The polymer80 rl556v3 – rhino 80% ar15 lower receiver and pf940c 80% pistol frame (black only) is a straight-forward combination for builders who want two different platforms from one purchase.
