Overview

The 80 percent lower is a partially machined receiver that requires final milling or drilling to become a functional firearm frame. It is not a finished firearm and may be purchased without an FFL transfer. This specific unit is manufactured from 7075-T6 aluminum, offering strength and corrosion resistance for long-term service. Every unit is inspected for dimensional accuracy before shipment, ensuring you receive a clean, consistent platform for your build.

Features & Specs

• Manufacturer: 80. Material: 7075-T6 aluminum, hard coat anodized for durability and wear resistance.
• Compatible with standard AR-15 mil-spec upper and lower parts kits. Includes integral trigger guard and flared magazine well for easier reloads.
• Pre-drilled selector markings and safety detent holes. Requires only basic tooling to complete: drill press, router, or jig. No welding or specialized machinery needed.

All critical pin holes, pocket dimensions, and thread locations are pre-machined to tolerance. The remaining material is clearly marked for finishing. This 80 percent lower ships ready for your attention.

Who It’s For

This product is intended for individuals who are legally permitted to manufacture a firearm for personal use under federal law. It is not for commercial resale or for use by prohibited persons. The 80 percent lower is ideal for hobbyists, gunsmiths, and DIY builders who prefer to complete their own firearm frame rather than purchase a finished receiver. If you are comfortable using a jig and basic power tools, this component gives you full control over the final fit and finish of your build. Always verify your state and local laws before purchasing, as some jurisdictions regulate or prohibit the possession of unfinished receivers.
