FX Panthera Butt Stock Dovetail?

Well, in our Czech Republic, Air-G-tac.com manufactures a complete new stock for FX Panthera Dynamic where it is possible to screw either a monopod directly into the bottom of the bag rider or a picantiny rail for attaching a small tripod or other accessories. I have already ordered two pieces of this stock myself. They should be in stock during February according to the reply they sent me. Of course there will be a modified skeletonized version already.
