This kit brings together the essential lower receiver components in one box, letting you start with an unfinished 80% lower and finish it at home. No serial number, no FFL transfer on the receiver itself—just a clean, black receiver block and the parts you need to complete the lower.

Overview

The p80 g150 ar-15 80% receiver kit – black is designed for those who prefer to build their AR-15 from the ground up. The kit includes the iconic 80% lower receiver, which requires finishing with basic tools like a drill press and router. Polymer80 is known for their jig system and clear instructions, and this kit is no exception. Once you complete the receiver, you can pair it with any standard AR-15 upper receiver group to create a fully functional firearm. The black finish is durable and matches most rifle builds, giving you a professional look right out of the box. This kit is a direct reflection of the build-your-own ethos, and it stays true to the hands-on approach that Polymer80 has championed for years.

Features & Specs

This kit is not just a bare receiver. It comes with everything you need to finish the lower receiver assembly, minus the tools. Here are the key features and specifications:

• Complete 80% lower receiver – Unfinished black polymer receiver that requires final machining. No serial number, no FFL transfer required for purchase.
• Lower parts kit included – All necessary small parts like trigger guard, bolt catch, magazine release, and safety selector are included in the box.
• Polymer80 jig compatibility – Designed to work with Polymer80’s proprietary jig system (sold separately) for accurate and repeatable finishing.

Additional specs you should know before starting your build:

• Caliber compatibility – Accepts standard AR-15 upper receivers for .223/5.56, .300 Blackout, and other compatible calibers.

Who It’s For

This p80 g150 ar-15 80% receiver kit – black is ideal for the DIY rifle builder who values privacy and a hands-on approach. If you have basic mechanical skills, patience, and a few common tools, you can finish this receiver in an afternoon. It is also a great choice for those who want to avoid the paperwork and waiting period associated with a complete, serialized lower receiver. Whether you are building a dedicated target rifle, a lightweight field gun, or a custom project from scratch, this kit gives you the flexibility to choose every other component without being locked into a pre-assembled platform. It is not for someone looking for a plug-and-play solution, but if you enjoy the process of building as much as shooting, this kit will satisfy that itch.
