I purchased a box of CSMs and the Finecast Thousand Sons upgrade kit prior to the Wrath of Magnus coming out. So I sit down to build the CSMs using the kit to make them into Rubric Marines. Well, of course there isn't a warpflamer or a soulreaper cannon in these kits. But I do have the new kit of the Scarab Occult Terminators. I could take the soul reaper canon out of the Terminators' kit and use it with the Rubrics. I guess a normal flamer could be the warpflamer if I want it to be, correct?
So, should I put a soulreaper cannon in the Rubric squad or keep it for the Terminators?
So, that begs the question, what is the best way to configure the Scarab Occult Terminators and the Rubric Marines?
Also, I have the old Ahriman kit; I don't think there is anything different in this kit from the new one as far as game play is concerned, right?
Thanks in advance for your help.
