If you are looking to build a custom firearm from the ground up, starting with the right foundation is everything. Our 80 percent lower offers the perfect balance of reliability, durability, and ease of machining. Whether you are a seasoned builder or stepping into your first project, this component gives you the control you want over your build. And because we know you do not want to wait, we back every order with very fast shipping straight from our US warehouse.

Overview

An 80 percent lower is a partially machined receiver that requires you to complete the final material removal yourself. This part is not considered a firearm by federal regulation because it is not yet functional. Our 80% lowers are precision-forged from 7075-T6 aluminum, the same material used by top-tier manufacturers. Every blank is designed to meet mil-spec dimensions, so your build will align perfectly with standard upper receivers and parts kits. When you order an 80 percent lower from us, you get a clean, consistent platform that machines smoothly with basic tools.

Features and Specs

We manufacture these 80% lowers to strict tolerances so your finishing work is straightforward. Here is what you can expect from each unit:

• Forged from 7075-T6 aluminum for high strength and corrosion resistance
• Hard-coat anodized black finish that resists wear and scratches
• Mil-spec trigger pocket and fire control group dimensions for drop-in compatibility

Every 80 percent lower we sell is inspected before shipment. The pocket is roughly 80% complete, leaving you the trigger area and fire control cavity to finish. We include clear reference markings to guide your drilling and milling. Because this is a raw lower, you have the freedom to customize the trigger, grip, and stock exactly to your preferences.

• Pre-drilled takedown pin holes and safety selector detent channel
• Compatible with all standard AR-15 upper receivers and buffer systems
• No serial number required until you complete the machining (check your local laws)

Who It Is For

This 80% lower is built for anyone who wants complete control over their firearm build. If you enjoy hands-on projects and want a reliable platform that you finished yourself, this is your starting point. It is ideal for hobbyists who prefer to machine at home with a drill press or router jig. It also works well for gunsmiths who want to stock raw lowers and finish them on demand. We do not recommend this product for first-time builders who have not yet practiced on aluminum, but if you have basic tool experience, you will find the process rewarding.

• Home builders who want a custom lower without the wait
• Enthusiasts who prefer mil-spec dimensions and proven materials
• Anyone who wants very fast shipping on their 80 percent lower order

Shipping and FFL

Because an 80 percent lower is not a firearm, it does not require transfer through a Federal Firearms License (FFL) dealer. We ship directly to your door with no background check needed. All orders leave our facility within one business day, and we use expedited carriers to ensure very fast shipping across the United States. Please verify your local and state laws before purchasing, as some jurisdictions regulate 80% lowers differently. It is your responsibility to comply with all applicable laws. We do not provide legal advice, so if you have questions about your state’s requirements, consult a qualified attorney.
