P80 G150 AR-15 80% Receiver Kit – Gray

If you are looking to build a custom AR-15 from the ground up, the p80 g150 ar-15 80% receiver kit – gray delivers exactly what you need: a clean, unfinished lower receiver that puts the build process in your hands. Polymer80 is known for practical, durable designs, and this gray kit is no exception. It gives you the foundation to create a rifle that fits your preferences, without the paperwork of a serialized receiver. Whether you are a first-time builder or a seasoned hobbyist, this kit offers a straightforward path to a functional lower.

Overview

The Polymer80 G150 is an 80% AR-15 lower receiver kit that arrives as an unfinished block. It requires you to complete the remaining machining steps—drilling pin holes, milling the trigger pocket, and removing the fire control group shelf—before it becomes a functional lower. The gray finish is consistent and low-profile, and the kit includes all the jigs, drill bits, and end mill you need to finish the job. Because it is not a serialized firearm, it can be shipped directly to your door without going through an FFL transfer. This is a hands-on project for anyone who wants to understand the mechanical side of their rifle.

Features & Specs

The p80 g150 ar-15 80% receiver kit – gray is built around a tough polymer lower that mates with standard AR-15 upper receivers, parts kits, and buffer tubes. Here are the core specs and what you get in the box:

• Manufacturer: Polymer80 – a trusted name in the 80% receiver space, known for reliable jigs and consistent polymer molding.
• Category: Build Kits – includes the lower receiver, jig, drill bits, end mill, and instructions. No upper or parts kit included.
• Material: Reinforced polymer in a subdued gray finish. Compatible with mil-spec AR-15 components.
• Compatibility: Works with standard AR-15 LPKs, buffer tubes, and upper assemblies. No special modifications required.

This kit is designed to be finished with basic tools like a drill press or hand drill. The jig guides each cut precisely, so you can achieve a clean result even if you are new to machining.

• Requires drilling of trigger pin and hammer pin holes, plus milling of the trigger pocket and safety selector detent channel.
• No serial number, no FFL transfer needed for the unfinished receiver. You are building a firearm for personal use.
• All necessary jig components and cutting tools are included. You just supply the drill press or hand drill.

Who It’s For

This kit is for anyone who wants to build their own AR-15 from a p80 g150 ar-15 80% receiver kit – gray without the hassle of waiting on a background check at a gun store. It is ideal for DIY enthusiasts who enjoy the process of assembling a rifle from parts, whether you are building your first AR or adding another to your collection. If you have a standard LPK and an upper ready to go, this receiver kit is the missing piece. It is also a good choice for those who want to avoid serialized registration in states where that matters, but always check your local laws before ordering.

Shipping & FFL

Because the p80 g150 ar-15 80% receiver kit – gray is sold as an unfinished 80% lower, it is not classified as a firearm under federal law. That means it can be shipped directly to your home or business without needing an FFL transfer. No background check is required for the purchase of the receiver itself. However, once you complete the machining and assemble the receiver into a functional firearm, you are responsible for complying with all applicable federal, state, and local laws. Some states and localities restrict or prohibit the possession or manufacture of unserialized firearms or 80% receivers. It is your responsibility to verify that owning and finishing this product is legal in your jurisdiction. We do not ship to locations where such products are restricted.
