Nope, other than the takedown detent pin and spring jumping out when you remove the existing tube and plate.

I wrote the below guide when the UBR was in prototype status, but the basic information is still the same. The QD sockets are different on the production version, and the screw is slotted with a drain hole instead of using an allen wrench, but aside from that it should give you all the info and pictures you need.

Its a pretty easy swap.
