Not 100% sure about the K version, but the regular version fits the ZF5 with one small mod. The buffer bumper in the brace is a little thin. Caused my ZF5 to keep sticking with the bolt to the rear. Seems it would recoil too far back and catch. I changed the bumper out with the one from my ZF5 (needed a slightly longer bolt to work...easy to find at my local hardware store). Ran 100% after that. I would guess the K version has the same quirk.
