80% Lower Fire/Safe Marked – Raw

If you’re building a custom AR-15 from the ground up, the 80% lower fire/safe marked – raw is one of the most straightforward starting points you can choose. This un-machined lower receiver comes with the selector markings already engraved, so you don’t have to worry about adding your own stencil or laser work later. The raw aluminum finish means you can anodize, cerakote, or polish it however you like—or just leave it as-is for a bare-metal build. This is a solid, no-frills component for anyone who wants to complete their own lower without paying for branding or pre-applied finishes.

Overview

This 80% lower fire/safe marked – raw is a partially machined AR-15 lower receiver that requires finishing before it can function as a firearm. The “80%” designation means the critical fire control pocket and trigger pin holes are not fully cut—you’ll need to complete those steps using a jig and basic tools. The “fire/safe” markings are already engraved on the side in clear, legible lettering, so your final build will have professional-looking selector labels without extra effort. The raw 7075-T6 aluminum billet gives you maximum flexibility for finishing, and the receiver is compatible with standard AR-15 upper parts kits and buffer systems.

Features & Specs

This raw 80% lower is built to tight tolerances, but still leaves you room to customize the finish. Here’s what you’re working with:

• Manufacturer: 80% – Category: Parts – Raw 7075-T6 aluminum billet with a clean, uncoated surface
• Pre-engraved “Fire” and “Safe” selector markings on both sides in standard depth and font
• Compatible with mil-spec AR-15 LPKs, buffer tubes, and aftermarket triggers (minor fitting may be required)

The 80% lower fire/safe marked – raw also includes a fully machined magazine well and takedown pin holes, so the only work you need to do is the trigger pocket and selector detent channel. It’s a great middle ground between a bare forging and a completed receiver.

• Includes front and rear pivot pin detent holes (pre-drilled) – no drilling required there
• Marked with a standard “Safe” (semi-auto) position – not a full-auto cut
• No serial number, no background check required to purchase (see FFL disclaimer below)

Who It’s For

This 80% lower fire/safe marked – raw is ideal for the DIY builder who wants to learn the machining side of AR assembly without buying a separate engraving service. If you already have a jig and a router or drill press, you can finish this lower in an afternoon. It’s also a good choice for someone who wants to test a custom cerakote or anodizing job without ruining a completed receiver. If you’re a first-time builder, the pre-marked selector positions take one variable off your plate—you won’t have to guess where to drill the detent hole or align the markings later.

This raw lower is not for someone who wants a drop-in, ready-to-shoot receiver. You will need to complete the fire control pocket, drill the trigger and hammer pin holes, and finish the selector detent channel. But if you’re comfortable with basic tool work and want a clean, unbranded start, this is a great pick.

Shipping & FFL

Because the 80% lower fire/safe marked – raw is not a finished firearm, it does not require transfer through a Federal Firearms License (FFL) holder. It can be shipped directly to your home or business address with no background check. However, once you complete the machining and make it functional, it becomes a firearm under federal law. You are responsible for understanding and following all local, state, and federal laws regarding the manufacture and possession of homemade firearms. Some states and municipalities restrict or prohibit the possession of unfinished receivers—check your local regulations before ordering. We do not provide legal advice, and you assume all liability for compliance.
