80% Lower Fire/Safe Marked – Raw

Build your next AR-15 platform with precision and control. The 80% Lower Fire/Safe Marked – Raw is a non-serialized receiver blank, machined to 80% completion, requiring final milling to accept a standard lower parts kit. This raw aluminum forging offers the cleanest starting point for custom builds, with clearly engraved fire and safe selector markings for a professional finish. No serial number, no FFL transfer required for purchase.

Overview

The 80% Lower Fire/Safe Marked – Raw is a direct-from-manufacturer component designed for personal use builds. Manufactured by 80%, this lower receiver blank is made from 7075-T6 aluminum, the industry standard for mil-spec durability. The raw finish means no anodizing or coating, allowing you to apply your own surface treatment or leave it as-is for a lightweight build. The fire/safe markings are laser-engraved into the side of the magazine well, providing clear indexing for your selector switch after completion. This part is classified as a firearm component, not a complete firearm, and can be shipped directly to your home in most states.

Features & Specs

This 80% Lower Fire/Safe Marked – Raw delivers consistent geometry and clean machining from the first cut. The 80% jig compatibility is standard, accepting all major drilling and milling templates.

• Material: 7075-T6 aluminum forging, raw (unfinished) surface
• Markings: Laser-engraved FIRE and SAFE selector positions on both sides
• Compatibility: Accepts all mil-spec AR-15 lower parts kits and buffer tube assemblies

The blank comes pre-drilled for the trigger pin, hammer pin, and bolt catch, though final pocket milling is required for the fire control group pocket and trigger slot. All critical dimensions match mil-spec drawings, ensuring proper fit with upper receivers and stocks.

Who It’s For

The 80% Lower Fire/Safe Marked – Raw is built for the home gunsmith, hobbyist, and builder who wants to complete a lower receiver from scratch. It is intended for individuals who have access to a drill press, router, or CNC setup and understand the legal requirements for manufacturing a firearm for personal use. This is not a drop-in part; it requires finishing work before it can accept a lower parts kit. If you are assembling your first 80% build, this raw marked lower provides clear guide reference points during the milling process. Experienced builders will appreciate the consistent forging quality and the option to customize the final finish. This product is not designed for commercial manufacture or resale as a completed receiver without proper licensing.

Shipping & FFL

You are responsible for verifying all local, state, and federal laws before placing an order. No FFL signature is required upon delivery. Shipping is via USPS Priority Mail or UPS Ground, with signature confirmation optional. The 80% Lower Fire/Safe Marked – Raw is sold as a raw forging; no warranty is expressed or implied regarding the ease of completing the receiver. By purchasing, you confirm you are legally eligible to own firearm components and that you intend to complete this blank into a firearm for personal use only.
