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 delivers two complete 80% builds in a single package: the RL556V3 AR-15 lower receiver with its dedicated jig, and the PF940Cv1 compact frame with its jig, compatible with Glock 19 and 23 Gen 3 parts. Both components are finished in black and require final machining by the end user. Each 80% lower receiver is a precisely molded polymer blank that allows you to complete the fire control cavity and related features using the included jigs. This bundle is designed for builders who want to start two projects simultaneously without sourcing jigs separately. The RL556V3 and PF940Cv1 are among the most popular platforms in the 80% market, and this combination offers a streamlined path to a finished AR-15 rifle and a compact pistol frame.

Features & Specs

Each component in this bundle is manufactured to Polymer80’s specifications, using reinforced polymer for the frames and precision-machined jigs for accurate drilling and milling. The RL556V3 AR-15 lower receiver accepts standard mil-spec AR-15 lower parts kits and buffer tubes, while the PF940Cv1 compact frame is designed for Glock 19/23 Gen 3 slide and barrel assemblies. Both jigs are reusable and include drill bits and end mills where applicable.

• RL556V3 AR-15 80% Lower Receiver: Compatible with all mil-spec AR-15 upper receivers, LPKs, and buffer tubes. The included jig features hardened steel drill guides and a removable fixture block for precise trigger pocket and safety selector machining.
• PF940Cv1 Compact 80% Frame: Direct fit for Glock 19/23 Gen 3 slides, barrels, and lower parts kits. The jig includes front and rear rail alignment tools and a drilling template for the trigger housing pin holes.
• Both units: Black textured polymer finish with integral grip texture and trigger guard. Jigs are constructed from aircraft-grade aluminum and polymer composites for repeated use. Each 80% lower is serial-number-free until completed by the builder.

Who It’s For

This bundle is intended for experienced firearm builders who have the tools, workspace, and knowledge to complete 80% lower receivers. The RL556V3 and PF940Cv1 platforms require access to a drill press, router or Dremel-type tool, and basic gunsmithing skills. This is not a beginner kit: you should be familiar with AR-15 and Glock 19/23 assembly procedures before attempting to machine either 80% lower. The bundle is ideal for builders who want to create a custom AR-15 rifle and a compact pistol frame from the same manufacturer, using jigs designed specifically for these receivers. If you already own Polymer80 jigs for either platform, this bundle still provides a cost-effective way to add a second build without buying duplicate jigs.
