No off the shelf 5/8" extension bumper exists to my knowledge. But any cuemaker could change those threads to M16x1.5, so you can use the standard Predator extension.

I agree... I can't find one
If needed There was another cue that had nothing to screw too that I done awhile back and I just put in a plug, drilled, tapped to accept the m16x1.5
