RL556V3 80% AR15 Lower – Black

Building your own AR-15 from the ground up is a rewarding project, and the foundation of any reliable build starts with a solid lower receiver. The RL556V3 80% AR15 Lower in black is a popular choice for DIY enthusiasts who want to take full control of their firearm’s fit, finish, and function. Whether you are assembling your first rifle or adding a new platform to your collection, this lower offers a clean canvas for your next build.

Overview

An 80% lower receiver is an unfinished component that requires you to complete the fire control pocket and trigger pin holes using a jig and basic tools. The RL556V3 is machined from a rugged 7075-T6 aluminum forging, giving it a strong, mil-spec feel without the premium price tag of a fully finished receiver. It is designed to accept standard AR-15 parts kits and buffer tube assemblies, making it a straightforward choice for anyone comfortable with a drill press or router. The black anodized finish provides a durable, corrosion-resistant surface that will hold up through years of range time and field use.

Shipping & FFL

Because the RL556V3 is an 80% lower receiver and not a finished firearm, it can be shipped directly to your home address without needing a transfer through a Federal Firearms License (FFL) dealer. However, once you complete the receiver by drilling the fire control pocket, it becomes a firearm in the eyes of the ATF and must be handled according to federal, state, and local laws. We recommend checking your local regulations before purchasing. We ship to all states where 80% lowers are legal, using discreet packaging with tracking provided. No FFL transfer is required for this item, but please verify your local laws regarding possession and completion of unfinished receivers.
