I'm in a pickle

[biodsl]

I wanted a light weight 20" upper build when I was putting my 2nd upper together, so went with the faxon gunner profile barrel as it appeared to be the lightest 20" production tube I could find. And considered each part of the upper for function vs weight and made my choices.

Sadly, this barrel seems to be out of production. I don't think there was anything quite like it on the market.
