Anyone ever parted ways with a rifle and been messaged a week later with a crazy claim? Sold a feller a complete AR with a 223 wylde chambered upper last week. He asked a million questions about 556 compatability etc. I did the best to provide links to him so he could read up on it himself. He agrees to purchase and we meet up. He never tried to talk me even a cent off of my asking. Out of the blue today I get a message that I'm a liar because he went to the gun shop and the guy at the counter said anything marked 223 can't fire 556. He won't say which shop...long story short I told him sorry but he's wrong and that we were done talking. First time in 25ish years wheeling and dealing that's happened to me. Did I handle it correctly or should I have provided more info?
