interdynamic,intratec,now what?

I got this interdynamic kg99 some may remember from posts before it has a feed problem that i think is narrowed down to a mag catch problem i guess the part is rare but obtainable, however i do not have the knowledge to fix the gun myself...that leads to my question....interdynamic was "bought and sold " and renamed intratec my understanding is that they(intratec)also went out of business. does anyone know if this company exists under a new name?and if so would i be able to send it to them to get fixed? i would like to get this gun working right and keep it i really don't intend to sell as my understanding is that these guns and the open bolt tec-9s where both fairly reliable and rare, in the days before they started producing junk. thanks again for any help
