Here is a used HK 21 Hk21 Hanger which has seen some better days. I have others in similar condition.. Came in a soggy cardboard box.. I have the other half as well.. And a lot more… Heckler and Koch items. Shoot me a note. Must have been stored in a damp place it has some rust and bumps in the paint. Just passing it on.. If you are happy with it.. If not, pls don’t.. Neither one of us wants a headache.. It is a Drum hanger.
