Please help me understand what is considered acceptable behavior because looking at this thread I can see how mocking and intimidating new members is fair game if you've run up a large post count, but calling out such behaviors is not. What am I missing?
Sure, let me help you understand. Your intentions might be honorable, but what we saw was a new guy who didn't get the answer he wanted and decided to respond by jumping on other members. Your ill-tempered response made you seem like the troll in this situation, which prompted more questions about what you were up to regarding a conversion. So it's fair to say you got off to a bad start by not displaying the positive, supportive attitude you say you appreciate in other members. I'm sure you can see the irony in the situation. None of this is grounds for throwing you off the site, which is my ongoing duty to assess, but it does color people's opinion of you and they way they interact with you. "Hey..." was suggesting you take the high road and chill out a little bit, which seems like good advice. You can't control the quality of the responses you get in a public forum, but you can control how you react to it.
As far as Mini UZI carbines go, you're right that there aren't many around. Vector didn't sell that many to begin with so I wouldn't expect to see many of them, but wherever they are, the owners don't seem motivated to sell them. Most of the Vector Minis were cut down from full size receivers, so a person could do that with a new receiver now and not be any worse off. Of course the problem is finding someone who will do a quality job at a reasonable cost. I don't think there are any secrets to finding one of the Vectors. Just keep watching and post WTB ads. Sooner or later something will turn up. Since you don't have a registered bolt yet, it would see that there's no rush.
