I have a brand X shotgun with a typical bead type front site. I was shooting the other day and noticed that there was a little indentation inside the barrel where the bead site was soldered to the barrel. You can definately see the front site shaft when looking in the barrel. I'm thinking some of the solder broke off. It's not obstructing the barrel but I'm pretty sure it's not normal. Just wondering if anyone has ever seen this.
