80% Lower Patriot Pack

For builders seeking a reliable foundation for their next rifle platform, the 80% Lower Patriot Pack delivers a precision-machined, un-serialized lower receiver ready for completion. This pack is designed for the individual who values hands-on craftsmanship and wants full control over their firearm’s build process. As a raw 80% forging, this component requires final machining to become a functional lower receiver, adhering to all applicable federal regulations regarding unfinished firearm parts.

Overview

The 80% Lower Patriot Pack is a purpose-built component for firearm enthusiasts who prefer to construct their own platforms from the ground up. Manufactured by 80% Arms, this part falls under the Parts category and is machined from high-grade aluminum billet. The pack includes all necessary jigs and tooling to assist in the final milling process, ensuring accurate pocket depths and trigger group pin hole alignment. This product is intended for builders who understand the mechanical and legal responsibilities of completing an 80% lower receiver.

Features & Specs

Every 80% Lower Patriot Pack is built to strict tolerances, ensuring compatibility with standard mil-spec upper receivers, lower parts kits, and buffer tube assemblies. The pre-machined fire control pocket is 80% complete, requiring only final routing of the trigger and hammer pin holes, as well as the safety selector pocket. The following specifications define this pack:

• Material: 7075-T6 aluminum billet, hard coat anodized in black for corrosion resistance and durability.
• Compatibility: Accepts all mil-spec AR-15 upper receivers, lower parts kits, and collapsible stocks.
• Included tooling: Integrated drill guide jig, end mill bits, and step-by-step instruction booklet with dimensional callouts.

The 80% Lower Patriot Pack is designed for use with standard drill presses or hand drills, though a router or milling machine is recommended for precise pocket finishing. The pack does not include any serialized components, requiring the builder to complete the lower and optionally mark it per local regulations.

Who It’s For

This pack is intended for experienced firearm builders, hobbyists, and DIY enthusiasts who have the tools and knowledge to complete a lower receiver. It is not suitable for first-time builders without prior machining experience, as the final drilling and milling steps require careful attention to depth and alignment. The 80% Lower Patriot Pack is ideal for those who want to customize their trigger group, safety selector, and grip without purchasing a complete, serialized lower. It is also a practical option for individuals who prefer to build multiple platforms with identical lower receiver geometry.

Shipping & FFL

Because the 80% Lower Patriot Pack is classified as an unfinished, non-serialized receiver, it does not require transfer through a Federal Firearms License (FFL) dealer when shipped within the United States. However, customers must verify that their state and local laws permit the ownership and completion of 80% lowers. Some states, including but not limited to California, New York, and New Jersey, impose restrictions or outright bans on unfinished receivers. By purchasing this product, you acknowledge that you are solely responsible for compliance with all applicable federal, state, and local laws. The 80% Lower Patriot Pack ships directly to your door via common carrier, with adult signature required upon delivery. No FFL transfer is necessary for this product, but we recommend consulting legal counsel if you have any questions regarding your jurisdiction’s requirements.
