WTK: HK Slimline hand guard, 9.5" These fit which model?

[Dscheid NFA Investments 57]

OK, I found these in my HK stuff and forgot what they fit?

Pictured is (top) HK93, 33 wide. 2nd down is a slim line, both are 11.5" length.

3rd one with the pin pointing to it is the one in question, 9.5" in length, but which model does it fit at 9.5"  G3K or 33K?

Bottom one is for the HK51/53/MP5 and so on at 6.5"

Thanks for any help!
