Tennessee Arms - Polymer 80% Lower "Liberator" with Jig (AR-15, Black)



With things growing more and more uncertain in the world today, there's still one thing that remains certain: if you want something done right, do it yourself. This is exactly the kind of thinking that'll take you far in this industry over the long-term. Why? Because you'll be self-sufficient. Now it's time to take that self-sufficiency to the next level. You want an AR-15? Build it yourself. Bring the desire and either the minimum necessary knowledge or the ability to learn, and we'll get you there. You'll start with a solid lower receiver, one that you finished yourself.

This is the Liberator polymer 80% lower receiver by Tennessee Arms Company. Unlike typical aluminum lowers with which you could start your build, polymer lowers are lighter in weight while still very durable. And TAC takes it a step further and integrates a tough brass insert into the buffer tube attachment point for even more strength. Plus, you take either the knowledge or the ability to gain the knowledge mentioned before and put it with the jig that comes with it, and you've got yourself a hell of a lower receiver ready to be built out into your next AR. Yep, it comes with the damned jig too, and even tooling if you want it. So get on it. Be the certainty in these uncertain times. You want it done right, so do it yourself with the Liberator by Tennessee Arms Company.

Liberator 80% Lower Features:

  • Made from easy-to-finish lightweight nylon
  • Buffer tube area reinforced with tough brass insert
  • Jig needed to finish it are included (tooling optional add-on)

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
