eBay (*spit*) has decided that following the law isn't good enough. Instead, they're going to ban the sale of any part that can make a gun go "bang".
You know, long after they decided to be a gun unfriendly site, I continued patronizing various vendors who sold there, because by doing so I was supporting small businesses (usually) and the minimal amount I enriched eBay's coffers was more than offset by the fact I was buying gun parts using a service ran by hoplophobes. I liked that.
I suppose after mid-August, I'll be buying things elsewhere. eBay, eBye.
