Product Overview

For the dedicated firearms enthusiast seeking a hands-on project, the Polymer80 RL556V3™ and PF940Cv1™ Bundle represents a comprehensive starting point. This bundle combines two of the most sought-after 80% platforms into one convenient package: a polymer AR-15 80% lower receiver and a compact pistol frame compatible with Glock 19/23 components. Each comes with its dedicated, precision-machined jig. Designed for the experienced hobbyist who values the process of building and customizing their own firearms, this kit is intended for personal manufacturing in compliance with all applicable laws. The primary use is to provide a robust, weapons-grade polymer foundation for a custom semi-automatic rifle and pistol build, offering a deep sense of accomplishment and tailored ergonomics.

Key Features

• Dual-Platform Bundle: This 3-in-1 combo includes both an RL556V3 AR-15 80% lower and a PF940Cv1 compact frame, along with their respective jigs, providing exceptional value and project versatility.
• Precision Engineering & Jigs: Each component is paired with a proprietary, easy-to-use jig system. These jigs are engineered to guide the machining process accurately, ensuring proper alignment of critical fire control group holes and cavities for a reliable final product.
• Weapons-Grade Polymer Construction: Both the lower receiver and frame are molded from high-strength, reinforced polymer. This material offers a durable, lightweight foundation that is resistant to corrosion and environmental wear.
• Broad Parts Compatibility: The RL556V3 lower accepts standard AR-15 lower parts kits, triggers, and buffer systems. The PF940Cv1 frame is designed to work with readily available aftermarket and OEM Glock 19/23 parts kits, slides, and barrels.
• Stainless Steel Reinforcements: Critical stress points, such as the rear rail module on the pistol frame and various pin locations, incorporate stainless steel components. This ensures long-term durability and reliable semi-automatic action under repeated use.
• Ergonomic & Customizable Foundation: The PF940Cv1 frame features an ergonomic grip angle and textured surfaces, providing an excellent base for stippling or other custom modifications to suit your preference.

Performance & Applications

Custom Home Defense Platform: A builder can utilize this bundle to create a tailored home defense system. The AR-15 platform allows for the configuration of a lightweight, maneuverable carbine, while the compact pistol frame can be built into a reliable, holster-ready sidearm. The ability to select every component—from triggers to sights—enables optimization for reliability and user-specific handling.

Advanced Marksmanship & Training: For the shooter interested in competitive shooting or dedicated practice, building from an 80% platform allows for unparalleled customization. You can install match-grade triggers, specialized grips, and other performance parts from the outset, creating a firearm perfectly tuned to your technique for improved accuracy and control during training sessions.

Technical Hobby & Skill Development: This project is ideal for the individual who appreciates the mechanical intricacies of firearms. The process of completing the frames using the provided jigs develops practical machining and assembly skills, resulting in a deep, functional understanding of the firearm’s operation and a strong personal connection to the finished build.
