P80 G150 AR-15 80% Receiver Kit – Gray

If you are looking to take full control of your next build, the p80 g150 ar-15 80% receiver kit – gray is a solid starting point. Polymer80 has been a go-to name in the DIY firearms community for years, and this kit delivers exactly what you need to create a custom AR-15 lower without the hassle of serialized paperwork. We have handled a lot of these kits, and the gray finish is a clean, understated choice that pairs well with nearly any upper receiver.

Overview

The p80 g150 ar-15 80% receiver kit – gray is designed for builders who want a reliable, unfinished lower that they can complete at home. This kit includes the 80% receiver, a universal jig, and all the necessary bits to finish the machining process. Because it is an 80% receiver, it is not considered a firearm under federal law until you complete the fire control pocket. That means no background check at purchase and no FFL transfer required for the receiver itself. The gray color is molded through, so it resists scratching better than painted surfaces.

• Includes the 80% lower receiver, jig, drill bits, end mill, and instruction manual
• Gray polymer construction with a textured grip area for enhanced control
• Compatible with standard AR-15 lower parts kits and mil-spec buffer tubes

Features & Specs

Polymer80 built this kit with the home builder in mind. The p80 g150 ar-15 80% receiver kit – gray uses a reinforced polymer that holds up well under normal use, and the integrated trigger guard saves you time during assembly. The jig system is straightforward to use with a standard drill press or hand drill, and the guide holes are pre-marked for the fire control pocket and safety selector. We recommend taking your time with the machining steps to ensure a clean fit for your trigger group.

Who It’s For

This kit is ideal for experienced builders who want to avoid the paperwork and wait times associated with a serialized lower. It is also a great choice for anyone looking to learn the machining process on a budget-friendly platform. If you already have a parts kit and a stock sitting around, the p80 g150 ar-15 80% receiver kit – gray is a practical way to turn those components into a working rifle. Just keep in mind that you will need basic tools like a vise, drill, and a steady hand.

• Best for intermediate to advanced DIY builders comfortable with hand tools
• Perfect for customizing your AR-15 without a serialized lower
• Not recommended for first-time builders without prior machining experience

Shipping & FFL

Because this is an 80% receiver and not a completed firearm, it ships directly to your doorstep with no FFL transfer required. We do ask that you confirm your local and state laws before ordering, as some jurisdictions have restrictions on unfinished receivers. Federal law does not require a background check for this item, but you must be at least 18 years old to purchase. Our shipping team processes these kits within one business day, and we use discreet packaging. Be aware that once you complete the receiver, it becomes a firearm under federal law and must be serialized if you plan to transfer it later. For any questions about your specific state regulations, please contact us before placing your order.
