Polymer80 RL556V3 and PF940Cv1 Bundle – 80% Lower Receiver with Jig, AR15, and 80% Compact Frame with Jig, G19/23 Compatible (Black Only)

Overview

If you are ready to take on a pair of build projects that give you real control over your firearm’s ergonomics and finish, this bundle is your starting point. The Polymer80 RL556V3 and PF940Cv1 Bundle – 80% Lower Receiver with Jig, AR15, and 80% Compact Frame with Jig, G19/23 Compatible (Black Only) combines two of the most respected 80% platforms on the market. You get the RL556V3 AR-15 lower and the PF940Cv1 compact frame, both in durable black polymer, and each one ships with its own complete jig kit. No need to hunt down separate tooling or measure out drill depths by eye – the jigs are pre-engineered to guide your bits exactly where they need to go. Whether you are building a full-size rifle or a concealed-carry pistol frame, this Polymer80 RL556V3 and PF940Cv1 bundle covers both ends of the spectrum in one clean package.

Features & Specs

The RL556V3 lower receiver is machined from a tough, glass-reinforced nylon polymer and accepts standard AR-15 parts kits and buffer tubes. The PF940Cv1 compact frame is built for Glock 19 and 23 gen 3-compatible internals, giving you a full grip length with a compact slide profile. Both lowers come as 80% blanks, meaning the critical fire-control cavities are unfinished and require you to complete them using the included jigs.

• RL556V3 lower: accepts mil-spec AR-15 upper receivers, trigger groups, and buffer systems; integrated trigger guard; reinforced front takedown pin boss.
• PF940Cv1 frame: compatible with G19 and G23 gen 3 slides, barrels, and lower parts; features an accessory rail and textured front/rear grip serrations.
• Each jig kit includes drill bits, end mills, alignment pins, and step-by-step instructions specific to that model – no guesswork between the two builds.

Because this is the Polymer80 RL556V3 and PF940Cv1 Bundle – 80% Lower Receiver with Jig, AR15, and 80% Compact Frame with Jig, G19/23 Compatible (Black Only), you can work on both projects simultaneously or tackle one at a time. The jigs are reusable, so if you decide to build additional lowers later, you already have the tooling on hand.

Who It’s For

This bundle is aimed at the home builder who wants to expand from one platform into two without doubling their tool investment. If you already own a basic drill press or a handheld drill and a vise, you have everything else you need to finish these receivers. It is also a solid choice for someone who wants to compare the feel of a full-size AR grip angle against a compact pistol frame before committing to a particular style. The Polymer80 RL556V3 and PF940Cv1 Bundle – 80% Lower Receiver with Jig, AR15, and 80% Compact Frame with Jig, G19/23 Compatible (Black Only) gives you two distinct projects that teach different milling techniques – one for a straight-walled receiver pocket, and one for a curved frame rail system. If you are comfortable with basic shop safety and following a drill guide, you can complete both lowers in a weekend.

• Perfect for the builder who wants to finish an AR-15 rifle lower and a compact pistol frame in one order.
• Great for shooters who prefer a modular platform and want to customize grip texture, trigger feel, and overall fit without paying a gunsmith.
• Ideal for anyone who appreciates the self-sufficiency of completing their own firearm components at home.

Shipping & FFL

Because these are 80% receivers, they are not classified as firearms by the ATF and do not require transfer through a Federal Firearms License holder. The Polymer80 RL556V3 and PF940Cv1 Bundle – 80% Lower Receiver with Jig, AR15, and 80% Compact Frame with Jig, G19/23 Compatible (Black Only) ships directly to your door. No FFL is needed for purchase or delivery. However, once you complete the receivers by milling out the fire-control pockets, you are responsible for complying with all local, state, and federal laws regarding the serialization and transfer of homemade firearms. Check your state and local regulations before beginning your build. We recommend keeping a build log and marking the completed frames with a unique identifier as a best practice.

• No FFL required for this 80% bundle – ships to any residential or business address in eligible states.
• You are solely responsible for ensuring your completed build is legal in your jurisdiction.
• All jig components are included; no additional tooling necessary beyond basic shop equipment.
