I was wondering if anyone ever got ripped of by a dishonest purchaser in this site or a similar one?

The reason I was asking is that I dealt with a guy from Jackson Georgia who traded me an Encore 45 caliber muzzleloader barrel for my Encore 308 barrel. Mine was nearly NIB with about 50 rounds thru the bore and his was supposed to be in excellent condition. It turned out to be badly pitted inside the bore and really bad where powder was left in the breech area. He agreed to send me $100. to make up the difference but never did. I contacted the Encore Classified moderator but never got a reply. The guy gave all kinds of excuses as to why he never got around to sending the $100. Family emergency, close friend died, I'll send it out next week. He finally told me to F off. His name is Casey Mcrae BTW and goes by Trumpvoter77 on the Encore Classified site......Nimblehunter
