Words can not express how disappointed I am with that design
I love DD rails and have been waiting for well over a year for them to come out with a Keymod version but I was hoping for and expecting something with a little better then that.
Looks like all they did was cut the 3 extra rails off of their DDM4 rail and then milled Keymod slots into it. I'm sure more work went into it then that but that's what it looks like. I was hoping for something smoother like the BCM and KAC Keymod forearms. I guess I will have to start seriously looking at those other options
