It's common in guns, typcally for sling swivel mechanisms.

If it's any help, I think H&K builds a weapon
that latches the bolt with a similar mechanism.

I wouldn't be surprised. H&K make some beautiful things.

A google search term of "sling swivel" looks very promising, especially
"quick detachable". Maybe you can find a cross-section, or a source for
purchase that way.
