Overview

This rl556v3 80% ar15 lower – gray is manufactured from 7075-T6 aluminum, the industry standard for strength and longevity. The 80% configuration means the critical fire control pocket and trigger pin holes are left partially unfinished, requiring the end user to complete the machining to ATF specifications. The gray anodized finish is consistent across the entire receiver, with crisp edges and clean threads at the buffer tube and grip areas. Each receiver is inspected to ensure dimensional accuracy before leaving the factory, providing a reliable platform for a functional rifle.

Who It’s For

This rl556v3 80% ar15 lower – gray is intended for individuals with access to a drill press or milling machine, along with the necessary jigs and tools to complete the fire control cavity. It suits experienced builders who want to start with a high-quality blank and finish it to their own specifications. Whether you are assembling a single custom rifle or stocking multiple receivers for future projects, this lower provides the same structural integrity as a finished receiver without the additional machining done at the factory. It is not for those seeking a plug-and-play solution, but rather for builders who understand the machining requirements and legal responsibilities associated with 80% receivers.

Shipping & FFL

This rl556v3 80% ar15 lower – gray is classified as a non-firearm receiver blank and does not require transfer through a Federal Firearms License (FFL) for shipment. It can be shipped directly to your residence or business within the United States. However, once the receiver is completed to ATF specifications, it becomes a firearm and must be serialized per federal and state regulations. It is your responsibility to verify local and state laws regarding the purchase, completion, and possession of 80% receivers. We do not provide legal advice; consult an attorney or your local ATF field office for compliance.
