I have custom built 10.5" barreled .300 blackout upper. I put this together at the beginning of the year, test-fired it and put it away. It has been sitting inside my gun cabinet and I have decided to part ways with it as I’m building a Retro carbine.
This upper is in perfect condition, I spent more than what I’m asking for it but can’t find my build sheet!
Asking $300 shipped; DOESN’T include BCG or Charging Handle.
