P80 G150 AR-15 80% Receiver Kit – Flat Dark Earth

If you are looking to build a custom AR-15 from the ground up, the p80 g150 ar-15 80% receiver kit – flat dark earth is a solid starting point. Polymer80 has been a go-to name for DIY builds for years, and this kit brings their usual straightforward engineering to the table. The flat dark earth finish gives it a clean, tactical look that pairs well with most FDE or black accessories. This is a true 80% receiver, meaning you will need to finish the lower yourself before it is ready to use. It is a rewarding project for anyone comfortable with basic tools and a little patience.

Overview

The p80 g150 ar-15 80% receiver kit – flat dark earth is designed for builders who want control over their firearm without starting from scratch. The kit includes the 80% lower receiver, a jig, drill bits, and end mills necessary to complete the pocket and trigger group channels. The lower is made from reinforced polymer, which keeps the weight down while still holding up under standard use. This is not a finished receiver, so you will be responsible for the final machining steps before assembly. The flat dark earth color is applied consistently across the polymer, so it looks uniform out of the box.

Features & Specs

Polymer80 built this kit with the home builder in mind. The included jig is reusable, which is a nice touch if you plan on doing multiple builds. Here is what you get in the kit and what to expect from the receiver itself.

• Reinforced polymer 80% lower receiver in flat dark earth with a textured grip area for better control
• Includes a complete jig with drill guides, two drill bits, and two end mills for the trigger and safety holes
• Compatible with standard AR-15 mil-spec upper receivers, lower parts kits, and buffer tubes

Beyond the basics, the receiver uses a standard trigger pocket profile, so you can drop in most aftermarket triggers without additional fitting. The rear takedown pin area is reinforced to reduce wear over time. The jig itself is made from a durable plastic that holds alignment well during drilling, which is critical for a clean build. The kit does not include a lower parts kit or stock, so you will need to source those separately.

• Overall length of the receiver is standard AR-15 spec, so it will fit any mil-spec buffer tube and stock
• Weight of the bare receiver is approximately 8 ounces, keeping your overall build light
• Manufacturer part number is G150 for the flat dark earth variant

One thing to note is that the polymer used here is not the same as a billet aluminum receiver. It is more forgiving if you make a minor mistake during drilling, but it also means you should not use aggressive torque when tightening screws into it. Stick to hand-tight on any grip screw or bolt catch pin to avoid stripping.

Who It’s For

This p80 g150 ar-15 80% receiver kit – flat dark earth is best suited for intermediate builders who have some experience with tools like a drill press or a hand drill with a steady hand. If you have already built a few lowers from 80% receivers, this kit will feel familiar. It is also a good option for someone who wants a specific color like flat dark earth without having to cerakote a bare aluminum receiver afterward. The polymer holds paint well if you ever want to change the color later, but the factory FDE is already a solid match for most Magpul or B5 Systems furniture. Beginners can use it too, but plan to take your time with the jig instructions and go slow on the drilling steps.
