Bumping this up in hopes from some help from OP and/or MDT. I was in the same situation after a Cadex build utilizing a Cadex Field Strike chassis. I came across a used MDT Fixed to Fixed adapter so I hopped on it, but I've run in to an issue and not sure its solvable. I can get the stock and spacer attached to the MDT adapter just fine, but I don't seem to have a way to attach the MDT adapter to the chassis unless I am missing a piece? The MDT adapter portion that attached to the chassis utilizes a screw, however my chassis has no screw hole unfortunately. As you can see in the photos, there was a "threaded adapter plug" I'll called it (labelled #1) that I had to move to the other side of the MDT adapter to fit it to the stock. Is there another plug I can get for that chassis end that I can thread in which will have a female threaded hole for the MFT adapter screw?
Was your Tac 30 chassis threaded inside the female insert portion where the adapter fits?
Here is the original configuration:
Stock removed:
Spacer removed with plug still in chassis:
Plug and spacer removed :
Transferred the plug and spacer to the stock end on the MDT adapter, all works well.
Can't attached MDT chassis end to chassis:
No threaded hole in chassis.
