Daniel Defense is such a tease. Check out the image that they recently posted to their Facebook Page…
There is speculation around the internet that it is .308 precision rifle but, since they refer to the teased firearm as a new “DDM4” on their Twitter feed, I doubt that is the case.

A few barrels that could be be stainless steel (or in the white carbon steel) appear in the most recent Daniel Defense video on Youtube (below). Perhaps, given the potential appearance of stainless barrels and the precision oriented optic shown in the teaser pic, the newest DDM4 will be some kind of stainless barreled light precision setup.
