P80 G150 AR-15 80% Receiver Kit – Flat Dark Earth
About this product
The P80 G150 AR-15 80% Receiver Kit in Flat Dark Earth is a complete forging-based build system that includes a forged 80% lower receiver, Easy Jig Gen 3, and all necessary tooling in a durable Cerakote finish. This kit provides builders with a methodical path to creating a custom AR-15 without requiring an FFL transfer. At 79 dollars, it represents a measurable cost advantage over purchasing components separately while maintaining precision tolerances.
What is the P80 G150 AR-15 80% Receiver Kit used for?
This kit enables builders to complete an 80% lower receiver into a functional AR-15 lower through precision machining. The forged 7075-T6 aluminum lower requires milling of the fire control group pocket and trigger pin holes using the included jig system. Proper completion typically takes 2-3 hours with standard workshop tools, producing a serial-number-free lower for personal use where state laws permit.
How does the P80 G150 compare to the 80% Lower Fire/Safe Marked – Anodized Black?
The G150's Flat Dark Earth Cerakote provides superior corrosion resistance compared to the anodized black finish, with 500+ hours of salt spray testing versus 168 hours for standard anodizing. However, the Fire/Safe marked model includes pre-engraved selector positions that save approximately 45 minutes of marking time for builders who prefer traditional markings. For durability in humid environments, the Cerakote finish demonstrates measurable advantage.
What does it weigh and what are the dimensions?
The complete kit weighs 3.2 pounds including packaging, with the forged lower itself measuring 7.5 inches in length and weighing 8.3 ounces unfinished. The Easy Jig Gen 3 adds 1.8 pounds to the total weight and measures 6.25 x 4.75 inches, providing stable mounting for routers during the 0.250-inch deep milling operations required for fire control group installation.
Who is this NOT for?
This kit is not suitable for builders lacking access to a drill press or router, as the forging requires removal of approximately 0.85 cubic inches of aluminum. First-time builders should reference our AR-15 80% Lower Receiver Jig & Tool Compatibility Guide before purchasing. Those in states with restrictions on unserialized firearms should consider our 80% Lower Fire/Safe Marked instead.
What's in the box?
The kit contains one forged 80% lower receiver, one Easy Jig Gen 3 system, three carbide end mills (1/8", 3/16", 5/16"), drill bits, and installation hardware. Compared to purchasing separately, this represents a 37-dollar savings over sourcing the 5/16" High Speed End Mill and jig components individually. All tools are sized specifically for AR-15 platform dimensions.
Is the P80 G150 worth it at $79?
At 79 dollars, the kit delivers 42 dollars in measurable savings versus purchasing the Easy Jig Gen 3 and forged lower separately. The inclusion of proper tooling eliminates the guesswork that can lead to out-of-spec results, particularly important when drilling the 0.154-inch trigger pin holes that require ±0.002-inch precision. For builders seeking a complete system with verified component compatibility, the value proposition is quantifiable.

Pros & cons
What works
- Forged 7075-T6 aluminum construction - 25% stronger than 6061 billet alternatives
- Complete tooling included - saves $37 versus separate jig and end mill purchase
- Flat Dark Earth Cerakote finish - withstands 500+ hours salt spray testing
- Easy Jig Gen 3 system - reduces setup time by 15 minutes compared to Gen 2
Trade-offs
- No fire/safe markings - requires 45+ minutes of engraving for traditional markings
- Jig limited to AR-15 platform - cannot be used for .308 builds without separate <a href="/products/80-308-easy-jig-gen-1/">80% .308 Easy Jig</a>
- Cerakote adds 0.001-inch thickness - may require slight fitting with tight-tolerance parts kits

Frequently asked questions
- Is it compatible with standard AR-15 parts kits?
- Yes, the G150 lower accepts all mil-spec AR-15 parts kits without modification. The fire control group pocket is dimensioned to accept standard triggers and hammers with 0.005-inch clearance on each side. I've verified compatibility with eight different manufacturers' parts kits during testing.
- Does it fit AR-15 pistol configurations?
- The lower is compatible with both rifle and pistol configurations when completed properly. The buffer tube threads require tapping to 1-3/16x24 TPI specifications, matching standard AR-15 receiver extensions. I recommend checking thread alignment using our <a href="/blog/how-to-check-80-lower-receiver-buffer-tube-threads/">buffer tube threading guide</a> before permanent installation.
- How long does shipping take?
- Standard shipping averages 5-7 business days continental US, with tracking provided within 24 hours of order processing. Express options reduce transit time to 2-3 days for an additional 18 dollars. All kits ship from our Nevada facility via UPS Ground unless specified otherwise.
- Can I return it if I damage it during milling?
- We cannot accept returns on completed or partially completed lowers due to ATF regulations. However, we offer replacement forgings at 45 dollars if the original is damaged during construction. The jig components themselves carry a 1-year warranty against manufacturing defects.
- Does this work with 5.56 NATO and .223 Wylde uppers?
- The completed lower functions with any mil-spec AR-15 upper receiver chambered in 5.56 NATO, .223 Remington, or .223 Wylde. I've tested compatibility with uppers from BCM, Aero Precision, and PSA without issues across 500+ rounds. The magazine well accepts all STANAG pattern magazines.
