This is an 80% lower receiver, the foundational component for building a custom AR-15. Machined from a 7075-T6 aluminum forging and finished with a Type III hardcoat anodize, it’s built for durability. It ships as an unfinished, unserialized component, requiring final machining by you to complete the firearm. It is designed for compatibility with standard AR-15/M16 parts kits and upper receivers.
Key Features
- 7075-T6 Aluminum Forging: Military-grade alloy for maximum strength and impact resistance.
- Type III Hardcoat Anodized: Superior surface hardness for wear and corrosion resistance.
- AR-15/M16 Compatibility: Works with standard mil-spec parts kits, triggers, and uppers.
- Unfinished Firearm Component: Requires final machining of the fire control cavity by the builder.
- Precision CNC Machining: Critical external dimensions and pin holes are pre-machined for accuracy.

As an unserialized 80% lower, this is a project for builders who value customization and understanding their firearm’s mechanics. The 7075-T6 forging is the same spec used by the military, ensuring your build’s core is robust. This is not a firearm until you complete the machining, a process that, under federal law, does not require an FFL transfer for personal use. Always verify your state and local laws before purchasing.
