For builders who demand precision without the premium price tag, the Polymer80 G150 AR15 80% Lower Receiver Only delivers a robust foundation for your custom AR-15 platform. This unfinished lower receiver is manufactured to exacting tolerances, providing the essential starting point for a legally compliant, do-it-yourself firearm build. As a non-serialized component, it allows you to complete your project with the tools and skill you bring to the bench, all while maintaining the structural integrity required for reliable performance.

Overview

The Polymer80 G150 AR15 80% Lower Receiver Only is a high-strength polymer receiver designed for the home builder. It is compatible with standard AR-15 upper receivers, parts kits, and magazines. The 80% state means the receiver is not yet a firearm under federal regulation, requiring you to complete the final machining steps yourself. This specific model from Polymer80 is known for its lightweight construction and reinforced stress points, making it a popular choice for both first-time and experienced builders seeking a cost-effective path to a fully functional rifle.

Features & Specs

• Material: Impact-resistant, reinforced polymer for reduced weight and increased durability. The G150 design incorporates a reinforced buffer tube tower and trigger pocket to withstand repeated use.
• Compatibility: Accepts all standard mil-spec AR-15 lower parts kits, buffer tubes, and pistol grips. Compatible with any mil-spec AR-15 upper receiver.
• 80% Completion: Requires final machining of the trigger pocket, safety selector holes, and fire control group pocket. No serial number is present, allowing for personal completion in accordance with federal law.
• Weight: Approximately 8 ounces, significantly lighter than comparable aluminum receivers without sacrificing structural integrity.
• Finish: Textured grip surface for enhanced control, with a matte black finish that resists wear and solvents.

Who It’s For

This product is intended for the skilled DIY builder who understands the machining requirements of an 80% lower. It is ideal for hobbyists, gunsmiths, and enthusiasts who want to build a custom AR-15 from the ground up, without the cost or wait associated with serialized receivers. You will need access to a drill press, router, or jig system to complete the fire control pocket. This is not a drop-in component; it is a project for those who value the process of building as much as the final product. The polymer80 g150 ar15 80% lower receiver only is also a practical choice for those in states where 80% receivers remain unrestricted, offering a legal avenue for personal firearm fabrication.
