TNArms AR-15 Liberator Polymer 80% Lower with Jig (OD Green)



As our industry continues to evolve, more and more of us have stopped buying ARs and started building them ourselves. You're becoming part of that cross section of us, or you wouldn't be here. Every great AR build starts with a great lower receiver. And what makes it great? Well, it should have certain characteristics. Among those are being lightweight while still being strong and durable. Polymer lowers fulfill this role in an awesome way, especially the Liberator 80% lower by Tennessee Arms Company. This one comes to you in OD green, so you can go for that outdoorsy or military look.

The Liberator 80% lower by Tennessee Arms Company isn't like your usual polymer 80% lower. It's made of lightweight nylon. Plus, the buffer tube area comes reinforced with a tough brass insert to maintain its strength. The OD green color will give off that old-school military vibe too. Oh, and to finish machining your Liberator 80% lower, the jig is included along with the option for the correct tooling. So what are you waiting for? You're here, because you realize that the advantages of building your own AR far outweigh the disadvantages. So grab a Liberator 80% lower by Tennessee Arms Company, and let us help you capitalize on your ingenuity.

Liberator 80% Lower Features:

  • Made from easy-to-finish lightweight nylon
  • Buffer tube area reinforced with tough brass insert

Why a Polymer AR-15 80% Lower?

Polymer 80% lowers have been well-tested and proven among the AR-15 and 80% lower community. They're ultralight and afford the same ruggedness as an aluminum lower, yet their construction also affords many unique benefits.

If you’ve never machined an 80% lower, this polymer lower will be the perfect way to ease into the practice. Polymer is incredibly simple to drill and mill, and the material is forgiving.

Tennessee Arms recommends that uppers from the following brands work best with their lowers:

  • Aero Precision
  • Head Down
  • SSA
  • DPMS
  • JSE Surplus
  • Delta Team Tactical
