Description

You’re looking at the most straightforward path to a custom AR-15 build. The Polymer80 G150 80% Receiver Kit eliminates the guesswork and extra parts hunting. This isn’t just a blank; it’s a complete system engineered for a clean, professional finish. We’re talking about Polymer80’s latest Gen2 polymer composite technology, packaged with every tool required. If you want a durable, functional lower without the paperwork, this OD Green kit is your starting point.

Product Overview

The P80 G150 Kit is a turnkey solution for finishing an AR-15 lower receiver. At its core is the G150 Gen2 lower, crafted from Polymer80’s advanced Phoenix2 polymer composite. This material uses a solid core design and reinforced areas at the buffer tube housing and magwell to handle the stresses of a rifle platform. The kit is distinguished by its inclusive nature: the precision-machined aluminum jig, a 7/16″ end mill with laser-etched depth mark, a 5/16″ trigger pin hole drill bit, and a 3/8″ safety selector drill bit are all in the box. The innovative no-thread pistol grip boss means you simply torque down the grip screw to secure the grip—no threading the receiver itself. This is a complete, intelligently designed package for a one-stop build.

Key Features

• Phoenix2 Polymer Composite: Proprietary formula with a solid core for increased strength and reduced flex compared to traditional polymers.
• Stiffened Magwell & MILSPEC Buffer Tube Housing: Critical reinforcement points ensure reliable magazine insertion/ ejection and secure stock attachment.
• Complete Jig System: Precision aluminum jig guarantees correct hole placement and milling depth for a perfect finish.
• All Tools Included: Comes with the specific 7/16″ end mill, 5/16″ trigger pin drill, and 3/8″ safety selector drill—no need to source separate tools.
• No-Thread Pistol Grip Design: Simplifies assembly; the grip screw creates its own threads as you tighten, eliminating a complex machining step.
• OD Green Finish: Durable, non-reflective finish straight from the mold, ready for your custom build.

It is designed for use with standard AR-15 lower parts kits (LPKs), fire control groups, buffer tubes, stocks, and pistol grips. The buffer retainer and rear takedown pin detent channels are pre-molded, so installation of those small parts is straightforward. This is a versatile foundation for building a rifle in any configuration you choose.

Real-World Use Cases

This kit is for the builder who values a streamlined process. It’s ideal for creating a lightweight hunting or ranch rifle, where the polymer lower shaves ounces without sacrificing strength.

Frequently Asked Questions

What tools do I need besides what’s in the kit?

You will need a drill press or a sturdy handheld drill, a vise to secure the jig, and basic safety equipment (eye protection). The kit provides the specific drill bits and end mill for the machining operations.

Is the finished lower as durable as aluminum?

The Phoenix2 composite is engineered for the AR-15 platform. The solid core and reinforced critical areas provide significant strength and rigidity. For the vast majority of uses, including standard rifle calibers, it offers excellent durability and a notable weight savings.

Does the no-thread grip design work with any AR grip?

Yes, it works with any standard AR-15 pistol grip that uses a screw. As you tighten the grip screw, it forms threads directly into the polymer boss, creating a very secure connection without the need for pre-tapping.
