Edit to my original post because I can't figure out how to delete it. Long story short this time, AoA gave me the wrong size barrel. After dealing with them on fixing this issue, I am more than pleased. The gentleman I spoke to today on the phone was happy to help and was a pleasure to deal with. I understand mistakes are going to be made, and it's how those mistakes are dealt with that really matters. Big thumbs up to AoA for working with me to resolve this matter!!!!!!
