Aero Precision RL556v3 80% AR15 Lower – White

Description

Product Overview

For the dedicated firearms enthusiast who values the process of creation as much as the final result, the Aero Precision RL556v3 80% AR15 Lower in White represents a foundational component for a custom build. This is an 80% lower receiver, meaning it is not a firearm and requires machining and assembly to complete. It is designed for individuals who are legally permitted to manufacture a firearm for personal use and who seek the satisfaction and customization of a true DIY project. The RL556v3 is engineered to serve as the core of a versatile AR-15 platform rifle, suitable for applications ranging from recreational shooting and training to hunting and home defense, once completed and in compliance with all federal, state, and local laws.

Key Features

• Proprietary Polymer Composite: Constructed from Polymer80’s reinforced polymer composite, this lower offers a significant weight reduction compared to aluminum while maintaining durability and structural integrity through a solid core design.
• Enhanced Ergonomic Design: Features a flared magwell for faster, more intuitive magazine changes and a uniquely designed pistol grip area with a threadless system specific to Polymer80 rifle lowers, ensuring a solid and seamless interface with compatible grips.
• Reinforced Critical Areas: The buffer tube housing is engineered to be beefier than standard designs, providing increased strength and stability where the receiver interfaces with the stock or pistol brace assembly.
• Complete Machining Kit Included: Each RL556v3 comes with a dedicated polymer jig, trigger hole drill guide, and the necessary drill bits and end mill, providing all the specialized tools required to properly complete the receiver.
• Mil-Spec Compatibility: Designed to accept standard mil-spec AR-15 parts kits, upper receivers, magazines, and accessories, guaranteeing broad compatibility and simplifying your build process.
• Multiple Finish Options: Available in a clean White finish, as well as Black, Flat Dark Earth (FDE), OD Green, and Gray, allowing for personalized aesthetic choices for your project.

Performance & Applications

The primary application of the Aero Precision RL556v3 is as the starting point for a personalized AR-15. Its performance is directly tied to the quality of components used to complete it and the skill of the builder. Once properly machined and assembled with quality parts, the completed lower forms the foundation for a highly adaptable firearm.

For the recreational shooter and hobbyist, this lower is ideal for building a dedicated .22 LR training rifle. The polymer construction keeps weight minimal, and the project itself provides deep understanding of the platform’s mechanics. For the hunter seeking a lightweight, maneuverable tool, a completed build using this lower in a caliber like .300 Blackout or 6.5 Grendel can be an excellent choice, with the white finish offering a unique base for camouflage. As a platform for training and skill development, the process of completing the 80% lower builds hands-on knowledge that translates to better maintenance, troubleshooting, and customization skills for the end user.
