80% Lower Patriot Pack

Designed for builders who demand precision from the first cut, the 80% Lower Patriot Pack delivers a complete substrate for custom firearm assembly. This pack provides the foundational component for constructing a legally compliant, personally finished lower receiver. Each unit in the pack is manufactured to strict dimensional tolerances, ensuring compatibility with standard mil-spec upper receivers and parts kits. For the serious hobbyist or small-volume manufacturer, the 80% lower patriot pack represents a practical and efficient way to stock essential build platforms.

Overview

The 80% Lower Patriot Pack consists of multiple unfinished lower receivers, each requiring final machining to become a functional firearm component. These receivers are fabricated from 7075-T6 aluminum, a material chosen for its strength-to-weight ratio and resistance to deformation under stress. The pack is intended for individuals who possess the necessary tooling and expertise to complete the fire control pocket, trigger slot, and safety selector hole. By starting with an 80% lower patriot pack, the builder retains full control over the finishing process, from jig setup to final surface treatment.

Features & Specs

Each receiver in the 80% Lower Patriot Pack is forged and machined to exacting standards. The critical dimensions are held to within 0.005 inches of mil-spec blueprints, minimizing the need for additional fitting during assembly. The pack includes multiple receivers, allowing for parallel work or spare units for future projects.

• Material: 7075-T6 aluminum forging, hard coat anodized per Mil-A-8625 Type III, Class 2
• Compatibility: Accepts all standard AR-15 upper receivers, lower parts kits, and buffer tube assemblies
• Finish: Black anodized surface with a matte texture, resistant to corrosion and wear

Additional technical specifications include a weight of 0.95 pounds per receiver, a standard trigger guard profile, and a rear takedown pin lug that is fully indexed. The pack does not include a jig, but every receiver is machined with clearly marked pilot holes for the safety selector and hammer pin. This 80% lower patriot pack is shipped in a sealed, padded container to prevent surface damage during transit.
