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

Overview

This bundle from Polymer80 combines two foundational 80% platforms into a single build package: the RL556V3 AR-15 lower receiver and the PF940Cv1 compact frame. Both components are manufactured from reinforced polymer and arrive as 80% blanks, meaning the critical fire-control cavities and trigger housings are uncompleted and require finishing with the included jigs. The RL556V3 is compatible with standard AR-15 mil-spec upper receivers and parts kits, while the PF940Cv1 accepts Glock 19 and 23 gen3-style slide assemblies and lower parts. Both units are offered exclusively in black, with no cerakote or color fills applied. This bundle is intended for personal fabrication by the end user and is not a finished firearm.

Features & Specs

The polymer80 rl556v3™ and pf940cv1™ bundle – 80% lower receiver with jig, ar15, and 80% compact frame with jig, g19/23 compatible (black only) delivers a unified machining experience for two distinct platforms. The RL556V3 lower receiver includes the proprietary Polymer80 universal jig system, which indexes off the rear takedown pin and trigger pin locations to guide drilling and routing of the trigger pocket and hammer pin holes. The PF940Cv1 frame ships with its own dedicated jig and drill bits, specifically contoured for the compact 9mm/.40 S&W frame geometry. Both jigs are reusable and constructed from hardened aluminum guide blocks.

• RL556V3: accepts all mil-spec AR-15 lower parts kits, buffer tubes, and pistol grips; compatible with .223/5.56, .300 Blackout, and 9mm AR platforms with appropriate upper conversions
• PF940Cv1: G19/23 gen3 pattern; uses standard Glock trigger housings, locking blocks, and slide release assemblies; compatible with aftermarket slides and barrels
• Both jigs include step-by-step instruction cards, required drill bits, and end mills; no additional tooling beyond a drill press or hand drill is required

Who It’s For

This bundle is designed for the hobbyist builder who wants to complete two separate 80% projects simultaneously, sharing tooling and setup time. The RL556V3 is suited for builders assembling a custom AR-15 rifle or pistol from a stripped lower, while the PF940Cv1 serves those constructing a compact polymer pistol frame for concealed carry or range use. Both receivers require the user to complete the fire-control cavities, so purchasers should have basic familiarity with drilling polymer, using a guide jig, and finishing 80% lowers. The polymer80 rl556v3™ and pf940cv1™ bundle – 80% lower receiver with jig, ar15, and 80% compact frame with jig, g19/23 compatible (black only) is appropriate for intermediate builders who want two completed platforms from one order, but it is not recommended for first-time 80% builders unfamiliar with jig alignment and cavity finishing.

• Builders assembling an AR-15 and a compact pistol frame in parallel
• Users who already possess lower parts kits, slides, and barrels for both platforms
• Individuals who prefer two separate jigs rather than a multi-platform adjustable jig

Shipping & FFL
