You can find Aero uppers / lowers in stock and on hand at damm near every gun shop across the country for $60-75 and they are machined flawlessly compared to that.
Still waiting on my lower and if it shows up looking like that. I will be sending it back.
I love Geissele triggers and their Rails, but man they are starting to go down a road that makes it tough to stand behind them
