Are Apr and urd cam gears the same?

[Mallcrawl]

Was wondering if the cam gears are the same , so for instance are you able to switch between Apr x-1 and the ucon ems? Thanks

The URD gears are better made and from much better material. Other than that they do the same thing.

Much appreciated, any chance those ucons ready to ship yet?
