Aero Precision RL556v3 80% AR15 Lower – OD Green

Description

Product Overview

The Aero Precision RL556v3 80% AR15 Lower Receiver in OD Green represents a significant evolution in polymer lower design, engineered for the dedicated firearms enthusiast who values the personalization and fulfillment of a build project. This is not a finished firearm; it is an 80% lower receiver, meaning it requires machining and assembly to completion, intended for individuals who enjoy the hands-on process of creating their own precision rifle or pistol platform. Crafted from Polymer80’s proprietary reinforced polymer composite and finished in a durable OD Green, the RL556v3 is designed for builders seeking a lightweight, robust foundation for a custom AR-15. Its primary use is as the core structural component for a personalized build, suitable for applications ranging from recreational shooting and training to specialized competition setups, where a tailored fit and feel are paramount.

Key Features

• Solid Core Polymer Composite: Unlike hollow designs, this lower features a solid core construction with Polymer80’s proprietary formula, significantly increasing strength and durability at critical stress points while maintaining a lightweight profile.
• Flared Magwell & Enhanced Ergonomics: The integrated flared magwell facilitates faster, smoother magazine changes. The pistol grip area utilizes a unique threadless design specific to Polymer80 rifle lowers, ensuring a clean, secure fit with compatible grips.
• Reinforced Buffer Tube Housing: The lower includes a beefier, mil-spec buffer tube housing area engineered to withstand the repeated impact and torque from the recoil system, enhancing long-term reliability.
• Complete Machining Kit Included: Each unit 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 to 100%.
• Durable OD Green Finish: The finish is not merely cosmetic; it is a integral, hard-wearing OD Green coating applied to the polymer frame, offering both aesthetic appeal and added resistance to the elements.
• Mil-Spec Compatibility: Designed to accept standard mil-spec AR-15 upper receivers, parts kits, and accessories, ensuring broad compatibility and simplifying the sourcing of components for your build.

Performance & Applications

The RL556v3’s design directly informs its performance in specific scenarios. Its polymer construction and solid core engineering make it an ideal candidate for a dedicated training rifle. The reduced weight compared to aluminum lowers decreases fatigue during extended practice sessions, while the reinforced buffer tube ensures it can handle high round counts reliably. For builders focused on a specialized hunting or outdoor rifle, the OD Green finish provides practical camouflage, and the lightweight nature is a benefit when covering long distances on foot.

Furthermore, this lower excels as the foundation for a precision-oriented build where balance is key. The polymer frame can help shift the firearm’s weight distribution towards a heavier barrel and optic setup in the upper receiver, potentially improving stability. The flared magwell and ergonomic grip area contribute to efficient handling, which is valuable in dynamic shooting sports or tactical training courses where manipulation speed and shooter comfort are directly linked to performance.
