Polymer 80 Gen II Phoenix 80% Lower Kit

Feel the difference the second you pick it up! The Polymer80 Lower Receiver features rock solid frame, injection molded from a fully automated system that was two years in the making.

This system is designed as a complete kit. There are NO expensive jig kits and parts to purchase - Polymer80's system is a COMPLETE, all-inclusive package in one price!

The Phoenix Gen2 version features Polymer 80's proprietary polymer composite, a solid core design, stiffened Magwell and beefier Mil-Spec buffer tube housing. The pistol grip area features a unique no-thread design specific to Polymer80 lowers.

The jig is included in the price of this system. The kit comes with drill bits and the end mill bit that's required to finish your AR project the right way.


  • Unique reinforced polymer design with solid core design
  • ATF compliant design
  • Beefed up buffer tube ring and ribbing across the entire upper surface area
  • No-thread design on pistol grip area
  • Stiffened Magwell, ultra-light design
  • Build this kit using only a drill press or end mill
  • Build only takes up to one hour


Older versions used some screws to hold the jig in place. That was changed in 2015 and this newest version does not come with or require screws to hold the jig together.
