The Polymer80 RL556V3 – RHINO 80% AR15 Lower Receiver and PF940C 80% Pistol Frame bundle provides two essential 80% platforms in one purchase. This combination is for builders seeking a versatile project base for both a rifle and a compact pistol. The value is clear, and it’s become a consistent seller in our shop since we began stocking it in summer 2025, with repeat customers frequently returning for this specific kit.
Key Features
- Dual-Platform Bundle: Includes one RL556V3 (RHINO) 80% AR-15 lower receiver and one PF940C 80% compact pistol frame.
- Enhanced Polymer Construction: Both receivers utilize Polymer80’s reinforced polymer formula for durability and reduced weight.
- Jig-Compatible Design: Both are designed for use with Polymer80’s proprietary jig systems for precise completion.
- Stripped & Unfinished: Requires machining to 100% completion and finishing per ATF guidelines.
- Universal Compatibility: The PF940C frame is engineered for Gen 3 Glock 19/23 parts. Our staff notes a slightly tighter fit with Gen4 components compared to Gen5, which is not a functional issue but is noticeable during assembly.

Frequently Asked Questions
What tools are required to complete these 80% receivers?
You will need a drill press or router, a Polymer80-specific jig for each model, drill bits, and end mills. The process requires basic machining skills. Jigs are sold separately.
Are parts kits included with this bundle?
No. This is for the 80% receivers only. You will need to source a Lower Parts Kit (LPK) for the AR-15 and a parts kit/slide for the PF940C pistol frame separately to build a functional firearm.
What is the legal status of 80% receivers?
As unfinished receivers, these items are not classified as firearms by the ATF and can be shipped directly to most customers. However, it is the builder’s responsibility to understand and comply with all federal, state, and local laws regarding the manufacture and possession of firearms.
