Forged Fire/Safe Marked 80% Lower Assembly

If you are building a custom AR-15 from the ground up, the lower receiver is the foundation of your entire platform. The Forged Fire/Safe Marked 80% Lower Assembly gives you the core component you need to create a firearm that is truly yours. Machined from a solid billet of 7075-T6 aluminum, this raw lower is ready for you to finish at your own bench. It comes with the safety selector markings already engraved, so once you complete the pocket and trigger area, your lower will look and function like a factory-made receiver. This is the starting point for builders who want full control over their build without sacrificing quality or durability.

Overview

The Forged Fire/Safe Marked 80% Lower Assembly is exactly what it sounds like: an unfinished lower receiver that is 80 percent complete. You handle the final machining of the fire control pocket, trigger pin holes, and hammer pin holes. The receiver is forged from 7075-T6 aluminum, then hard-coat anodized in a classic black finish. The “Fire” and “Safe” markings are already laser-engraved on the side, so your finished lower will have clean, professional selector markings. This is a solid, no-nonsense starting point for anyone who wants to build a reliable AR-15 platform with their own hands.

Features & Specs

• Forged from mil-spec 7075-T6 aluminum for high strength and impact resistance; hard-coat anodized per MIL-A-8625F Type III Class 2.
• Pre-marked with “Fire” and “Safe” selector engravings; pre-tapped for grip screw and rear takedown pin detent.
• 80% completion state requires final machining of trigger pocket, hammer and trigger pin holes, and selector detent channel; compatible with standard AR-15 lower parts kits.

This forged fire/safe marked 80% lower assembly is designed for builders who want a mil-spec platform without the extra cost of a completed receiver. The forging process ensures the aluminum grain structure is aligned for maximum strength in critical areas. The hard-coat anodizing provides a durable, corrosion-resistant finish that holds up to heavy use. The pre-marked engravings mean you do not need to worry about adding your own selector indicators after you finish machining.

Who It’s For

This lower is built for the hands-on enthusiast who enjoys the process of finishing a receiver at home. If you have a drill press, a mill, or a jig setup, and you understand the dimensions of the AR-15 fire control pocket, this is an excellent project. It is also a solid choice for gunsmiths or small shop owners who want to offer custom builds to their clients. Whether you are building a lightweight field rifle or a precision setup, the forged fire/safe marked 80% lower assembly gives you a clean slate to work with. It is not for someone looking for a complete, drop-in lower; it is for the person who wants to say they machined their own receiver.

Shipping & FFL

Because this is an 80% lower receiver and not a completed firearm, it ships directly to your doorstep with no Federal Firearms License (FFL) transfer required. However, once you finish machining the receiver, it becomes a firearm under federal law. You must comply with all applicable local, state, and federal regulations regarding the manufacture and possession of a firearm. It is your responsibility to ensure you are legally allowed to complete and own this receiver in your jurisdiction. We recommend checking your state and local laws before purchasing. No FFL transfer is needed for this unframed receiver, but you must be 18 years or older to purchase.
