I've been working with Wiebad on their mini stock pad. It uses velcro straps that go underneath and are perfectly spaced for KRG's cheek piece.

I don't know if they have the latest updated version made yet, I'll contact them to see if they do. Their initial version wasn't as nicely cut as the last prototype I have.
Wiebad just got back to me, they have a new production line for the KRG Bravo Mini Stock pad, if you order it, please put in the comments you want the new updated one, otherwise they'll ship the some remaining older batch to you until they finish getting rid of them...
