P80 G150 AR-15 80% Receiver Kit – Black

The P80 G150 AR-15 80% Receiver Kit in Black is a foundational building block for those constructing a custom AR-15 platform rifle. Manufactured by Polymer80, this kit provides the primary components necessary to complete a lower receiver assembly, starting from an 80% finished state. It is designed for builders who prefer to machine and assemble their own firearm at home, following all applicable federal and state laws.

Overview

This 80% receiver kit includes the P80 G150 lower receiver, which is pre-machined to the 80% completion stage. The receiver requires final milling of the fire control pocket and trigger pin holes to be completed by the end user. The kit is built around Polymer80’s proprietary jig system, which simplifies the finishing process for those with basic tool access. The P80 G150 AR-15 80% Receiver Kit – Black is a direct replacement for standard mil-spec AR-15 lowers and accepts all standard AR-15 upper receivers, parts kits, and magazines. It is not a finished firearm and does not include a serial number until legally required by the builder’s state of residence.

Features & Specs

The P80 G150 AR-15 80% Receiver Kit – Black is constructed from reinforced polymer, offering a balance of weight reduction and structural integrity. The black finish is applied during the molding process and is consistent throughout the material. Key specifications and included items are as follows:

• Lower receiver is 80% finished: requires drilling of trigger pin holes and milling of the fire control pocket using the included jig system.
• Compatible with all standard AR-15 mil-spec upper receivers, lower parts kits, and buffer tube assemblies.
• Integrated trigger guard, flared magazine well for faster reloads, and a threaded bolt catch pin for easier installation.

The kit includes the P80 G150 lower receiver, the universal finishing jig, drill bits, end mill, and all necessary hardware for the jig setup. No firearm parts are included in the kit beyond the 80% receiver and its finishing tools. The receiver is made in the United States and meets Polymer80’s quality standards for material density and dimensional accuracy.

• Material: Reinforced polymer, black color molded in.
• Weight: Approximately 0.8 pounds for the receiver only.
• Compatibility: Accepts all standard AR-15 lower parts kits and buffer tube assemblies.

Who It’s For

This kit is intended for individuals who are legally permitted to manufacture a firearm for personal use under federal law and their state’s regulations. It is suitable for hobbyists, gunsmiths, and builders who want full control over the lower receiver’s fit and finish. The P80 G150 AR-15 80% Receiver Kit – Black is not for those seeking a complete, ready-to-fire rifle. It is designed for those with basic mechanical skills, access to a drill press or handheld drill, and the ability to follow detailed instructions. Builders must be at least 21 years of age and legally eligible to possess firearms under federal and state law.
