I actually am not sure that he knows it has a bulge. I did not mention it to him. Maybe my standards are too high? I don't think so, but I'm a pretty nice guy. So, here goes.
When I received the gun it was dirty, but it had been cleaned. It just hadn't been cleaned very well. So, if he never cleaned it that well it's possible he never saw it. But I cleaned the inside of the barrel pretty good, so if you look down it with enough light you can clearly see the ring. The bulge is difficult to see, even in person.
I did shoot this gun and it shot just fine. I didn't mention the bulge to him because I was scared he would try to say I did it. I'm confident I did not, however, as I noticed the crud built up in the ring before shooting it. I just didn't realize what it was.
A friend of mine and I were already getting ready to go to the range and I got the call from the gun shop saying my transfer was ready for pick up. So, we went and got it then headed back to my place to take a closer look at it. I wasn't happy with a few things and noticed it was a bit dirty so cleaned it up a bit and noticed the crud built up in the barrel but didn't clean it all the way.
I called the seller to discuss the things I was unhappy with and the possibility of returning it. I also told him I was going to the range and was thinking about shooting the gun. He said to go ahead and see how i like it and get back to him. So, we did. I liked the gun. I was leaning towards keeping it. Maybe a bulged barrel ain't as bad as it sounds and looks?
I cleaned it better the next day and realized it had the bulge. I thought about it long and hard and decided to just tell him I wanted to stick to my initial decision to return it. With all the legal mumbo jumbo in his ad and the way he talked I had a bad feeling about the whole deal.
