First off, I am NOT asking this to add to Tim W. or Constructors already Xtreme workload in fact I hope to do just the opposite. So if someone else knows the answer and can save'em the time I will be happy to hear it.
I have read many times that the only options available for the Xtreme are the ones listed on AR15Performance and Titan Armorys website. Great, I'm cool with that. However, when I opened up the link to the build sheet that Donna sent me this evening I see options listed that are not on the websites (Daniel Defense rails, PWS-FSC30 comp, etc.) and options on the websites that aren't on the build sheet (YHM forearm endcap on Titans site).
So what's the real deal here? I want to get this right the FIRST time with no f'ing around and keep these guys time free to build these kick ass uppers.
