That's bizarre, since Heckler & Koch is a British company (BAe Systems) - but I guess since it has operations primarily in Germany that comes into play.
There are German Federal non-proliferation laws that restrict HK from marketing firearms of a non-sporting use to the general public. This is beyond HK's control, as a market driven firm they would be more than happy to capitalize on the opportunity. Too many African cesspits and their child militias are armed with G3's, G41's, HK33's, seeing this Berlin tightly monitors and regulates any of HK's sales. So don't be hatin' on HK even despite their inflated prices.
