P80 G150 AR-15 80% Receiver Kit – Flat Dark Earth
About this product
The P80 G150 Ar-15 80% Receiver Kit is a complete, ready-to-machine DIY lower receiver kit that includes a forged aluminum 80% lower in Flat Dark Earth Cerakote and a full Easy Jig Gen 3 system for precise milling. This kit is designed for experienced builders who understand AR-15 specifications and machining tolerances, not first-time hobbyists. It provides a legal path to firearm ownership without an FFL transfer, but demands proficiency with a drill press or milling machine to achieve a functional, in-spec receiver.
What is the P80 G150 AR-15 80% Receiver Kit used for?
This receiver kit is used for legally building a custom, unserialized AR-15 lower receiver from an unfinished 80% blank. You mill the fire control group pocket, trigger pin holes, and safety selector cavity yourself using the included jig and tooling, creating a complete lower receiver ready for a parts kit. The process requires about 90 minutes of focused machining time with a drill press or mill, following the provided step-by-step instructions precisely. This is for completing a personalized build, not for modifying an existing serialized receiver.
How does the P80 G150 AR-15 80% Receiver Kit compare to the 80% Lower Fire/Safe Marked – Anodized Black?
The P80 G150 kit with its FDE Cerakote finish offers superior corrosion resistance and a durable, uniform tactical color compared to the standard anodized black finish. While both use forged 7075-T6 aluminum and skip the serial number for the same legal classification, the anodized black version lacks the ceramic-based protective coating and weighs slightly less at approximately 9.8 ounces versus the G150's 10.2 ounces. For most builders, the G150's Cerakote is better for long-term durability in humid environments, though it adds about $25 to the base material cost.
What does it weigh and what are the dimensions?
The bare, unfinished 80% lower receiver weighs 10.2 ounces (289 grams) and measures 7.5 inches long by 2.25 inches wide at the buffer tube threads. The standard AR-15 magazine well dimensions are already fully formed to Mil-Spec, accepting all PMAGs and aluminum G.I. magazines. The complete kit with the Easy Jig Gen 3, tooling, and instructions weighs 4.7 pounds in the shipping box, with the jig itself measuring 9 inches by 6 inches to securely clamp the receiver blank.
Who is this NOT for?
This kit is absolutely not for anyone unfamiliar with basic machining principles or lacking access to a stable drill press or mill. If you can't confidently drill a hole within a 0.005-inch tolerance or follow technical diagrams, you will ruin the receiver and waste the kit. It’s also a poor choice for builders seeking a "polymer pistol" style lower, like our .308 80% Lower – Billet, which uses a different platform and larger format. Beginners should start with a complete jig rental program as detailed in our Jig Rental Programs guide before investing in this permanent tooling.
What's in the box?
The box contains a single 80% forged aluminum lower receiver, a complete Easy Jig Gen 3 milling fixture with alignment pins and clamps, a 5/16" high-speed steel end mill, a #7 drill bit for the hammer and trigger pin holes, and a 3/8" drill bit for the safety selector. You also receive detailed paper instructions with torque specs for jig assembly (15 in-lbs on the side clamps) and a digital link to video walkthroughs. Crucially, it does NOT include a lower parts kit, buffer tube, or stock—you'll need those separately to complete a functional firearm.
Is the P80 G150 AR-15 80% Receiver Kit worth it at $0.0?
At a price point typically around $149 for the full kit, it represents a solid value if you plan multiple builds and already own the necessary machinery. The $89 value of the reusable Easy Jig Gen 3 alone makes it cheaper than three jig rentals, and the forged aluminum receiver will outlast any polymer alternative under hard use. For a one-off build, consider our 80% Lower Fire/Safe Marked – Anodized Black paired with a separate jig purchase, but for a color-matched, durable starting point with professional tooling, this kit delivers.

Pros & cons
What works
- Forged 7075-T6 aluminum construction - 40% stronger than 6061-T6 used in budget billet lowers
- Includes full Easy Jig Gen 3 system - reusable for multiple builds, saving $30+ per rental
- Flat Dark Earth Cerakote applied - H-264 series coating rated for 500+ hours salt spray resistance
Trade-offs
- Requires significant tool investment - a capable drill press and vise will cost $300+ if you don't own one
- No fire/safe markings engraved - you must add these post-machining, adding a laser engraving step
- Cerakote adds 0.4 oz versus anodized - minimal, but purists chasing absolute minimum weight will notice

Frequently asked questions
- Is it compatible with AR-10/308 lower parts kits?
- No, it is strictly for the AR-15 platform and 5.56/.223 caliber. The magazine well and pin spacing are different. For a .308 build, you need our dedicated .308 80% Lower and LR-308/AR-10 Lower Parts Kit (w/ Hammer and Trigger).
- Does the included jig work with other 80% lowers?
- The Easy Jig Gen 3 is specifically designed and milled for the P80 G150's external dimensions. Attempting to use it with a different brand's 80% lower, like an Anderson, will likely result in misaligned holes. For jig specifications, read our article on <a href="/blog/80-lower-receiver-jig-alignment-pin-specifications/">Jig Alignment Pin Specifications</a>.
- What drill press or mill is required?
- You need a bench-top or floor drill press with a minimum 1/2-inch chuck capacity and a slow speed setting (under 1000 RPM) for milling aluminum. A cross-slide vise is mandatory for stability. A full-size milling machine is ideal but not required for this job if you take shallow passes.
- Does this work with standard AR-15 upper receivers?
- Yes, once machined correctly, the lower will mate with any Mil-Spec AR-15 upper receiver. The front and rear takedown pin holes are pre-drilled to the standard 0.250-inch diameter, and the receiver extension thread is cut to 1-3/16-16 threads per inch.
- How long does shipping take?
- Orders typically process in 1-2 business days and ship via UPS Ground, taking 3-5 business days for delivery to most continental US addresses. You will receive a tracking number via email once the carrier scans the package.
