Nathan –
I got the upper and lower assembled easily on a Tennessee Arms stripped lower. It looks great. It test fired good. The only catch is I got a rifle style buffer tube that isn’t compatible with the brace I want to put on it. Easy enough to fix, but the emails I send them haven’t been answered yet and they say not to call, as it doesn’t go to them directly. We’ll see how it goes. This is still the most bang for the buck I can find out there.
