Description
This 80% lower is for builders who want a clean, unfinished foundation for their custom firearm project. It arrives ready for your jig and tools, giving you full control over the final machining and finishing. Since adding it to our catalog in late 2024, it has become one of our most-reordered items, with customers frequently coming back for a second build.
What Makes It Stand Out
- Consistent Quality: Sourced from a reliable manufacturer with consistently positive feedback for dimensional accuracy and material integrity.
- Builder-Ready Design: Features clean, well-defined fire control group pockets and pin holes that serve as precise guides for your jig.
- Lightweight Foundation: The raw forging is designed to minimize excess material, resulting in a lower final weight for your completed build.
- High Compatibility: Engineered to work with a wide range of aftermarket jigs, parts kits, and upper receivers for maximum build flexibility.
- Streamlined Profile: The exterior has a smooth, classic profile that’s ideal for custom engraving or a clean, professional finish.

No. This is an unfinished 80% lower receiver. It is not classified as a firearm and does not require an FFL transfer for purchase. It becomes a firearm only after you complete the final machining.
What tools do I need to complete it?
You will need a compatible jig, a drill press or router, appropriate drill bits and end mills, and basic workshop safety equipment. The process requires precision and patience.
Does it include a jig or parts?
This listing is for the 80% lower receiver only. Jigs, tooling, and firearm parts kits are sold separately. Ensure you have the correct jig for this model before starting your project.
