P80 G150 AR-15 80% Receiver Kit – Flat Dark Earth - polymer 80
About this product
What is the P80 G150 AR-15 80% Receiver Kit? It is a polymer lower receiver kit in Flat Dark Earth designed for AR‑15 builds, providing a CNC‑machined 80% lower with the Phoenix2 jig system. The kit includes all necessary components to finish a functional lower without a dedicated machine shop, and it ships ready for the final drill‑and‑pin steps.
What is the P80 G150 AR-15 80% Receiver Kit used for?
It is used to build a custom AR‑15 lower by completing the final 20% of material removal and assembly. The polymer construction reduces weight to 14.2 oz (403 g) while maintaining structural integrity, and the flat dark earth finish matches standard GA‑19 handguards.
How does the P80 G150 AR-15 80% Receiver Kit compare to the Polymer80 PF940V2?
The G150 is 0.3 in shorter in overall length (7.2 in vs 7.5 in) and 4 oz lighter, making it marginally more ergonomic for compact builds. Unlike the PF940V2’s glossy black, the G150’s Flat Dark Earth coating resists UV fading better than the PF940V2’s finish.
What does it weigh and what are the dimensions?
The lower weighs 14.2 oz (403 g) and measures 7.2 in long, 1.8 in wide, and 0.8 in thick, fitting standard AR‑15 buffer tubes without modification.
Who is this NOT for?
It is not for shooters who need a fully finished lower out of the box; the kit requires the user to complete the final 20% machining, install the trigger group, and perform a function test.
What's in the box?
The box contains the polymer lower receiver, Phoenix2 jig, 2 mm drill bit set (10 pieces), pins, two takedown pins, and a printed assembly guide. All components total 1.2 lb of material, fitting in a standard 12 × 9 × 2 in shipping box.
Is the P80 G150 AR-15 80% Receiver Kit worth it at $79?
Yes, at $79 it delivers a ready‑to‑assemble lower that saves roughly $120‑$150 compared to a fully finished aluminum lower. The cost-effective polymer saves weight and time, making it a solid value for DIY builders.
