One of the coolest things about the industry's evolution is that now you're no longer restricted to simply purchasing an AR at your local gun shop. Plus, if you get any sort of mind to upgrade, mod, or swap out parts after you buy it, well, you're stuck with parts you don't need. Now more and more, the inconvenience of an AR-15 not coming stock with everything you want on it and nothing you don't is a thing of the past. Why go buy one, when you can just build your own after having chosen every individual part yourself?

Every AR build starts with a lower receiver, and you can start with yours. Yep, I said "yours." When you machine and finish an 80% lower yourself, you legally become the "manufacturer." This means you can skip the paperwork, skip the FFL, and skip the trip to your LGS. So how do you do this? You do it with the Liberator 80% lower by Hybrid80. It's the first hybrid 80% lower receiver on the market, and it even comes with its own jig and all the tooling as an optional purchase if you want everything in oner purchase! Then you can get your build on and make your AR from exactly the parts you want and nothin' you don't.

Hybrid 80 Liberator AR15 80% Lower:

  • Made from easy-to-finish lightweight nylon
  • Buffer tube area reinforced with tough brass insert
  • Jig needed to finish it are included

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.

Hybrid 80 recommends that uppers from the following brands work best with their lowers:

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