Cdg lightweight

Looking at all the openings for springs, plungers and levers seems like lots of points of potential failure in hunting situations. Dirt, dust, mud, rain, cold/freezing Temps.

Then again I'm speculating and could be way off as well. I was planning on building a 7prc and 6mmCM in the near future and I don't think I will try this action.
 
Trying to get a feel for the comparative weight on this thing, as I've been waiting for ARC's LW action release since it was mentioned in the CDG thread. Zermatt's faq says the SA Origin is 28oz, anyone know off the top of their head if that includes the rail?
