Polymer80 G150 AR-15 80% Receiver Kit – Gray

If you are looking to build a custom AR-15 from the ground up with a clean, unfinished platform, the p80 g150 ar-15 80% receiver kit – gray is a solid starting point. Polymer80 has built a reputation for offering reliable, easy-to-finish lower receivers, and this G150 kit carries that tradition forward. Whether you are a first-time builder or a seasoned hobbyist, this kit gives you the core components you need to complete your lower without the hassle of a serialized receiver. We have seen these kits sell out fast, so when they are back in stock, it pays to grab one early.

Overview

The p80 g150 ar-15 80% receiver kit – gray is designed for the builder who wants a durable, lightweight lower receiver that is ready to be finished at home. This kit includes the 80% lower receiver, jig, and necessary hardware to get you started. The gray finish is consistent across the polymer frame, giving your build a clean, professional look without the need for additional coating. Polymer80 uses high-impact polymer that holds up well under standard use and keeps the overall weight of your rifle down. This is a build kit, not a complete lower, so you will need to finish the receiver pocket and install your preferred trigger and grip before assembly.

Features & Specs

This kit is built around the Polymer80 G150 platform, which is compatible with standard AR-15 parts and mil-spec triggers. The 80% receiver means you are getting an unfinished lower that requires final machining before it can accept fire control components. Here is what you can expect from the kit:

• 80% Lower Receiver: Unfinished polymer frame in gray, compatible with standard AR-15 upper receivers, buffer tubes, and stocks. The receiver requires drilling of the trigger and hammer pin holes as well as removal of the fire control pocket material.
• Complete Jig System: Includes a reusable jig with drill guides and instructions to help you finish the receiver accurately. The jig is designed for use with a standard drill press or hand drill, making it accessible for home builders.
• Hardware Kit: Comes with the necessary pins, springs, and detents to complete the lower once the receiver is finished. You will still need a lower parts kit and buffer tube assembly to finish the build.

This p80 g150 ar-15 80% receiver kit – gray is a straightforward build for anyone comfortable with basic tools. The polymer construction is lightweight and resists corrosion, and the gray color is consistent across the frame. Note that this kit does not include a trigger, grip, or stock, so plan accordingly.

Who It’s For

This kit is ideal for the home builder who wants to learn the ins and outs of AR-15 assembly without the paperwork of a serialized lower. It works well for those who want to customize their rifle from the ground up and prefer a polymer frame for weight savings. If you have a basic understanding of how an AR-15 functions and are comfortable using a drill press or hand drill, the p80 g150 ar-15 80% receiver kit – gray is a great choice. Keep in mind that finishing an 80% receiver requires patience and attention to detail, so it is not recommended for complete beginners who have never handled an AR-15 lower before. Experienced builders will appreciate the quality of the Polymer80 jig and the consistency of the gray finish.

Shipping & FFL

Because the p80 g150 ar-15 80% receiver kit – gray is an unfinished 80% receiver, it is not classified as a firearm under federal law. This means it can be shipped directly to your home without going through a Federal Firearms License (FFL) dealer. However, we strongly recommend checking your local and state laws before ordering, as some states and municipalities have specific restrictions on 80% receivers. Once you finish the receiver and assemble the firearm, it is your responsibility to ensure compliance with all applicable laws. No FFL transfer is required for this kit, but we do not ship to states where 80% receivers are prohibited. Please verify your local regulations prior to purchase.
