Tennessee Arms Company 80% Lower Receiver

My experience with this Tennessee Arms Company 80% Lower Receiver has been a journey…  I wanted to pick up a 80% lower, loved the idea of not having to machine it out (like aluminum ones) and saw that Tennessee Arms Company had reinforced some key areas on their polymer lower receivers.  So I picked one up.

It has been a struggle, with issues getting a lower parts kits to fit, modifying parts to get them to fit, etc.  Finally, when I was about to throw in the towel I contacted them, worked through the last issue with the engineer there, and got it running.  Now that it is functioning, I am pleased with it, but it was a journey…

*For frame of reference: I have had a FFL 07 (License to Manufacture Firearms) for the last 3 years, put together and shipped lots of AR-15 / M-4 type rifles and pistols all over the US.  Not my first rodeo.*
