Do they still sell the bullpup stocks? Where can I get them? I threw out all my old SGN's and can't find them in the ads. I fired a plastic futuristic looking one before but I didn't really care for it then since I was only eleven. Now I think the concept has merit. I don't like the long guns for house defense because I am not as comfortable moving around with them as I am with pistols. I recalled the bullpup design and now I want to re-try it.
