80% Lower Patriot Pack

If you are looking to start a build from the ground up and want full control over your project, the 80% Lower Patriot Pack is a solid foundation. This pack brings together the essential components you need to complete a receiver that is ready for finishing. Whether you are a first-time builder or a seasoned tinkerer, this kit simplifies the process without cutting corners on quality.

Overview

The 80% Lower Patriot Pack is designed for those who prefer to handle the final machining steps themselves. It includes a precision-machined 80% lower receiver that meets standard mil-spec dimensions, giving you a reliable starting point. This pack is built around the idea that you should have the freedom to customize your lower receiver without paying for extras you do not need. Each unit is made from 7075-T6 aluminum and is compatible with standard jigs and tooling, so you can finish it at home with the right equipment.

Features & Specs

When you open the 80% Lower Patriot Pack, you get a receiver that is already 80 percent complete, meaning the critical fire control group pocket and trigger pin holes are left for you to finish. This approach keeps you in compliance with federal regulations while giving you a hands-on building experience. Here are the key specifications and details:

• Manufacturer: 80% (reliable, USA-based production with consistent tolerances)
• Category: Parts (receiver is unfinished, included as a component for your build)
• Material: 7075-T6 aluminum with a hard coat anodized finish for durability
• Compatibility: Accepts standard lower parts kits, buffer tubes, and stocks designed for mil-spec receivers

• No serial number is present on the receiver, so you are responsible for marking it per local laws after completion
• Includes a detailed material spec sheet and basic build guide to get you started
• All critical dimensions are held to +/- 0.005 inch for reliable function after finishing

The 80% Lower Patriot Pack is a straightforward way to begin a custom lower receiver project. You get the raw receiver and the confidence that it will work with common jigs and fixtures.

Who It’s For

This pack is for anyone who enjoys the mechanical side of building and wants a hands-on role in completing their lower receiver. It is a good fit for hobbyists who have access to a drill press or router and are comfortable following step-by-step instructions. The 80% Lower Patriot Pack is also popular with builders who want to avoid unnecessary features or branding on their receiver and prefer a clean, unmarked starting point. If you are new to finishing 80% lowers, this pack provides a straightforward experience without complicated extras.

Shipping & FFL

Because the 80% Lower Patriot Pack contains an unfinished receiver that is not yet a firearm, it can be shipped directly to your home or business address. No FFL transfer is required for the purchase of this product. However, once you complete the receiver by machining the fire control pocket and installing parts, you must comply with all applicable federal, state, and local laws regarding firearm ownership and serialization. It is your responsibility to check local regulations before finishing the receiver. We recommend keeping a record of your build and following all legal requirements in your area.
