Need help translating this page

http://www.systemshock.info/supergun.htm
I'm looking to buy a Supergun a come across this page which is in German. Any one can help me out whether they are selling Superguns or not? Thanks.

It's a general info page on superguns (we call them MAKs over here (mobile Arcade Konsole)), how to build them and/or where to buy them.

There's a link to a page with various info pages and shops in there: http://www.systemshock.info/links.htm , some of them are based in English-speaking countries as well. The SystemShock site itself does not offer ready-to-run superguns, though.

Thanks a lot
