I just recently purchased an tm mp5k and it arrived with the endcap missing the sling swivel and with several extra holes drilled in it, probably to mount an m4 stock. I just want the swivel. Does anyone know a site where I can purchase the swivel and/or the endcap (I'd like to have one without the holes in it)?

I've looked all over and I can't for the life of me find these parts. I can find every other part for the mp5k but these. It's been very frustrating, especially since the seller advertised it as next to new (not that I'm knocking him, he didn't realize it wasn't supposed to be the way it was and he's offered to pay for the replacement of these parts if I can find them).

Thanks,
