Forged Fire/Safe Marked 80% Lower Assembly

If you are building from the ground up, you understand the value of starting with the right foundation. This Forged Fire/Safe Marked 80% Lower Assembly is exactly that: a solid, unfinished receiver that puts the control in your hands. It is machined from a standard 7075-T6 aluminum forging, which means you are working with the same material used in mil-spec duty rifles. The fire/safe markings are already engraved, so once you finish the pocket and trigger area, you have a clean, professional-looking lower ready for assembly. This is not a pre-built unit; it is a blank canvas for the builder who wants to complete their own firearm without the full serialization process.

Overview

This is a raw, unpainted 80% lower receiver that requires machining to be functional. It is designed for the home builder who has the tools and patience to finish the fire control cavity and trigger pin holes. The forging is clean, with crisp fire/safe markings on the selector side. Because it is at 80% completion, it does not meet the legal definition of a firearm, meaning it can be shipped directly to your door without an FFL transfer on the front end. It is a straightforward path to a custom build, provided you understand the legal responsibilities that come with completing it for personal use.

Features & Specs

The construction here is straightforward and proven. This forged fire/safe marked 80% lower assembly uses a mil-spec 7075-T6 aluminum forging, which is the industry standard for durability and corrosion resistance. The fire/safe markings are deeply engraved, not painted on, so they will not wear off with handling or cleaning. Here are the key details you need to know:

• Material: 7075-T6 aluminum forging, hard coat anodized in a raw finish (ready for your preferred coating or cerakote).
• Markings: Engraved “FIRE” and “SAFE” markings on both sides, with a standard selector detent hole pre-drilled for drop-in safety selectors.
• Compatibility: Accepts all standard AR-15 lower parts kits, buffer tubes, and pistol grips. No proprietary parts required.

This assembly is a true 80% lower. You will need to finish the trigger pocket, drill the hammer and trigger pin holes, and complete the selector detent channel. For the experienced builder, this is a straightforward afternoon project with a router and drill press.

Who It’s For

This lower is built for the hands-on enthusiast who values the process as much as the final product. If you are someone who prefers to mill your own fire control cavity and understand every part that goes into your rifle, this is the right starting point. It is also a solid choice for those looking to build a firearm without the paper trail of a serialized receiver, as long as you comply with all federal, state, and local laws regarding self-manufactured firearms. It is not for the casual first-time builder who lacks the tools or willingness to learn machining safety. If you are comfortable with a router and have a solid jig, this forged fire/safe marked 80% lower assembly will reward your effort with a reliable, custom build.

Shipping & FFL

Because this item is classified as an 80% lower receiver and not a finished firearm, it does not require a Federal Firearms License (FFL) for shipment. We can ship this directly to your residential address via UPS or FedEx. However, once you complete the machining, you are legally responsible for ensuring the finished firearm complies with all applicable laws in your jurisdiction. We recommend checking your state and local statutes regarding the manufacturing of firearms for personal use. Note: Some states and localities have specific restrictions on 80% lowers. By purchasing this item, you confirm that you are legally allowed to possess and complete this component. No FFL transfer is required at the time of purchase, but you must be 18 years of age or older to order.
