80% Lower Fire/Safe Marked – Raw

When building a custom AR-15 platform, the lower receiver is the foundation of your build. The 80% lower fire/safe marked – raw offers a blank canvas for the serious builder who demands precision and clarity in their markings. This component is a key step in creating a firearm that meets your exact specifications, with the safety selector engravings already in place to guide your final assembly.

Overview

The 80% lower fire/safe marked – raw is an unfinished, un-serialized receiver that requires final machining to become a functional firearm component. Pre-marked with clear, legible fire and safe engravings, this blank eliminates the guesswork for your selector positions. Manufactured by 80% in the Parts category, it is designed to meet mil-spec dimensions for compatibility with standard AR-15 upper receivers, trigger groups, and buffer systems. The raw finish allows you to apply your preferred coating or anodizing after completion.

Who It Is For

The 80% lower fire/safe marked – raw is intended for the experienced home builder who understands the legal and technical requirements of completing a firearm. It suits hobbyists who prefer to machine their own receivers, custom gun builders who want a clean start without pre-applied branding, and shooters who value the ability to serialize and finish their firearm as they see fit. This is not a drop-in component; it requires proper tools, knowledge, and compliance with all applicable federal, state, and local laws regarding firearm manufacture and ownership.

Shipping & FFL

This 80% lower fire/safe marked – raw is not a firearm under federal law and does not require transfer through a Federal Firearms License (FFL) dealer. It can be shipped directly to your doorstep. However, once you complete the machining process, you are legally manufacturing a firearm. You must comply with all regulations regarding serialization, background checks, and possession in your jurisdiction. We recommend consulting a firearms attorney or your local ATF field office before beginning work. No FFL transfer is required for this item, but you are responsible for understanding and following all laws that apply to you.
