About this product

80% Lower Patriot Pack

The 80% Lower Patriot Pack delivers the foundational component for building a custom AR-platform firearm without serialization requirements under federal law. This pack provides the essential raw lower receiver, machined to 80% completion, requiring final milling to function. For builders seeking maximum control over their firearm build from the ground up, this pack represents the starting point for a project defined by your specifications.

Overview

The 80% Lower Patriot Pack is manufactured to exacting tolerances using 7075-T6 aluminum, the same material used by major military and law enforcement manufacturers. Each receiver begins as a solid billet and is precision CNC machined to the 80% stage, leaving the fire control group pocket, trigger pin holes, and hammer pin holes undrilled. This unfinished state allows the builder to complete the lower receiver at home using standard jigs and tooling. The pack includes the bare lower receiver and all necessary hardware for final assembly once machining is complete. Whether you are a first-time builder or a seasoned gunsmith, the 80% Lower Patriot Pack offers a clean, compliant, and cost-effective entry point into firearm customization.

Who It’s For

The 80% Lower Patriot Pack is ideal for the serious firearms enthusiast who values self-reliance and hands-on craftsmanship. This product is intended for individuals who have the necessary tools, workspace, and technical knowledge to complete the final machining operations. It is not a drop-in component; it requires deliberate effort and precision to finish. If you are a hobbyist looking to expand your skills, a prepper building a redundant platform, or a competitor who wants a fully custom lower built to your exact trigger and grip preferences, this pack provides the clean slate you need. It is also well suited for small custom shops or gunsmiths who prefer to source raw receivers in bulk for client builds. Because this pack does not require an FFL transfer at the point of purchase, it offers logistical simplicity for buyers in most states, though you must verify your local laws before ordering.

Shipping & FFL

This 80% Lower Patriot Pack ships directly to your residential or business address anywhere that private ownership of unfinished receivers is legal. No Federal Firearms License (FFL) transfer is required for the purchase or shipment of this product as defined under current federal regulations. However, it is your sole responsibility to confirm that your state, county, and municipal laws permit the possession and completion of unfinished lower receivers. Some states and localities impose restrictions, registration requirements, or bans on the possession of 80% receivers. By purchasing this product, you certify that you are legally eligible to own and complete this component under all applicable laws. We recommend consulting with a local attorney or your state attorney general’s office if you have any questions regarding compliance. Once you complete the machining and assemble a functional firearm, federal law requires that you do not transfer that firearm to another person without complying with applicable background check and serialization requirements. Always prioritize legal compliance and safe handling practices when building and using any firearm component.
