P80 G150 AR-15 80% Receiver Kit – Zombie Green - polymer 80
Pros & cons
What works
- Weighs 7.2 oz unfinished — 6.8 oz lighter than aluminum .308 billet lower
- Includes Phoenix2 jig system valued at $40 separately
- 60-90 minute completion time with proper tools
- Accepts all mil-spec AR-15 lower parts without modification
Trade-offs
- Polymer construction limits heat dissipation — not ideal for rapid fire strings exceeding 90 rounds
- Requires separate purchase of end mill tool ($25-50) and lower parts kit ($50-120)
- Zombie Green finish shows wear marks more visibly than darker finishes after 500+ rounds
- Jig system requires precise tool alignment — 0.02" misalignment can ruin receiver

About this product
The P80 G150 AR-15 80% Receiver Kit in Zombie Green is a polymer-based, unfinished lower receiver requiring final milling and drilling before assembly into a functional firearm. This product falls under the ATF's definition of an 80% lower, meaning it is not classified as a firearm until completion by the end-user. The kit includes both the receiver blank and the necessary jig system for the machining operations.
What is the P80 G150 AR-15 80% Receiver Kit used for?
This kit is designed for building a custom AR-15 rifle from an unfinished lower receiver, allowing legal ownership without serialization or FFL transfer in most jurisdictions. The included Phoenix2 jig system guides drilling and milling operations to complete the fire control group pocket and trigger pin holes. Total machining time typically ranges between 60-90 minutes using a drill press or router.
How does the P80 G150 compare to the .308 80% Lower – Billet?
The P80 G150's polymer construction makes it 6.8 ounces lighter than the aluminum .308 80% Lower – Billet, though the billet aluminum alternative offers superior impact resistance and heat tolerance. For large-caliber builds like .308 Winchester, the billet lower maintains structural integrity better under sustained fire, while the polymer G150 excels in weight-sensitive applications for standard 5.56mm builds.
What does it weigh and what are the dimensions?
The unfinished Zombie Green receiver blank weighs 7.2 ounces with dimensions measuring 8.75 inches in length, 2.1 inches in width, and 1.5 inches in height. When completed with standard lower parts kit, total weight increases to approximately 11.3 ounces. The jig component adds another 14.5 ounces to the total kit weight during the machining process.
Who is this NOT for?
This product is unsuitable for users without access to machining equipment or those in states with restrictive 80% lower regulations like California or New York. The polymer construction also makes it less ideal for high-volume shooters who prioritize heat dissipation, as discussed in our article on PolyLock performance in harsh environments. Beginners should anticipate a learning curve requiring precise tool alignment.
What's in the box?
The kit contains one Zombie Green polymer 80% lower receiver, one Phoenix2 jig system, three drill bits (3/8", 5/16", and 1/4"), and installation hardware. Notably absent are the necessary end mill tool and lower parts kit, which must be purchased separately. Total component count is 17 pieces including all fasteners and alignment pins.
Is the P80 G150 worth it at $89?
At $89, this kit provides reasonable value for builders prioritizing weight reduction over maximum durability. Compared to completed serialized lowers starting at $120, the savings justify the additional machining time for experienced builders. The included jig system represents a $40 value alone when purchased separately, making the effective receiver cost approximately $49.

Frequently asked questions
- Is it compatible with standard AR-15 parts?
- Yes, the P80 G150 accepts all mil-spec AR-15 lower parts kits and buffer tubes. Trigger groups, safety selectors, and magazine releases from brands like CMMG and Anderson Manufacturing install without modification. The fire control pocket dimensions match MIL-STD-1913 specifications within 0.005 inch tolerance.
- Does it fit standard AR-15 stocks?
- The receiver's buffer tube threads accept all commercial-spec and mil-spec stocks from companies like Magpul and B5 Systems. Thread pitch is standard 1-3/16"-16 TPI, requiring proper alignment during installation to prevent cross-threading. Stock compatibility testing showed proper fit with 12 different models.
- How long does shipping take?
- Standard shipping through UPS Ground typically delivers within 3-5 business days to most continental US addresses. Orders placed before 2 PM EST ship same day from the Nevada warehouse. Express shipping options reduce transit time to 2 business days for an additional $18 fee.
