Polymer 80 - AR-15 80% Lower Receiver and Jig Kit



Ready to build an ultra-light AR-15? Looking for the most affordable 80 lower receiver-and-jig combo you can find? You've found both! We've partnered with the engineers over at Polymer 80 to bring you a new, innovative Polymer 80 lower receiver for the AR-15. Alongside our other polymer kits, we're excited to introduce the G150 Phoenix!

This ultra-light polymer lower weighs just 0.3 pounds. That's a 50% weight reduction (with a Lower Parts Kit installed) compared to a forged or billet 80 lower! Even though this lower's incredibly light, it's by no means weak: Engineers tested and proved the design, then reinforced the entire thing by 15%. The G150 Phoenix has already proven it's worth, handling thousands of 5.56 rounds without failure.

G150 Phoenix Polymer 80% Lower Features:

  • Weighs just 0.3 pounds
  • Composite solid core design
  • Stiffened magazine well
  • Reinforced buffer tube housing
  • Integrated trigger guard
  • Metal inserts for pistol grip, bolt catch pin
  • Includes proprietary jig
  • Works with any other 80 Lower Jig!

Why a Polymer AR-15 80% Lower?

Besides the obvious weight reduction, you get peace of mind knowing these units are just as strong as their aluminum counterparts. Also, polymer is easier to work with than aluminum. If you're not confident that you can build an AR-15 at home, this is the kit to buy. Even first-time builders can complete this lower with hand tools in less than 2 hours!

Plus, you won't have to worry about it getting dinged up while you run and gun.  Grab one now and see for yourself!
