Description

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 combines two of Polymer80’s most practical 80% platforms into a single purchase: the RL556V3 AR-15 lower receiver and the PF940Cv1 compact frame, both in black. Each component ships with its corresponding jig, allowing you to complete the machining process for a functional firearm at your own pace. The RL556V3 accepts standard AR-15 parts kits and buffer tubes, while the PF940Cv1 is compatible with Glock 19 and 23 generation 3 slide assemblies and internals. Whether you are building a full-size rifle or a compact pistol platform, this kit covers both ends of the spectrum without requiring separate jig purchases.

Features & Specs

Both frames are manufactured by Polymer80 from proprietary reinforced polymer. The RL556V3 lower receiver is designed for mil-spec AR-15 components and uses a standard buffer tube system. The PF940Cv1 frame matches Gen 3 Glock 19/23 specifications and includes an integrated trigger guard and dust cover for the locking block. Each jig is pre-drilled with alignment guides to simplify the milling process.

• RL556V3 lower receiver: compatible with all mil-spec AR-15 upper receivers, LPKs, and buffer tubes. Includes rear takedown pin detent hole and threaded bolt catch pin.
• PF940Cv1 compact frame: accepts Glock 19/23 Gen 3 slides, barrels, and lower parts kits. Features a 1913 picatinny accessory rail and textured grip panels.
• Both kits include a dedicated jig with drill bushings, end mills, and alignment pins. No additional tooling required beyond basic hand tools and a drill press or router.

Who It’s For

This bundle is intended for individuals who want to build both a full-size rifle and a compact pistol platform from 80% receivers without sourcing two separate jigs. It suits experienced builders who already have a parts kit for each platform, as well as those starting from scratch who want a matched set of frames. The RL556V3 is ideal for a standard AR-15 carbine or mid-length build, while the PF940Cv1 works for concealed carry or range use. Both frames require final machining, assembly, and serialization per applicable laws.

• Builders assembling an AR-15 rifle and a Glock 19/23 compact pistol simultaneously.
• Users who prefer black frames for a uniform appearance across both platforms.
• Individuals who want the convenience of a bundled jig set for two different 80% receivers.
