I've got a kind of tricky question for you.  If you had a pre-ban AR15 with a military upper, could you also own a post-ban AR15.  Could the pre-ban upper be considered constructive intent for the other weapon, even though the upper was installed on the pre-ban weapon.

Would this same reasoning also go with a M-16 dummy gun and a post-ban AR15?

I think VA hit the nail on the head.  Having a pre upper might be a concern for "intent" if you owned no pre lower, but since you have a legal lower to put it on, I don't think you would have a problem even you hosted a tupperware party for those ATF faggots....ahh, I mean gentlemen.

I also agree with him about if they want intent, they'll find it if you own nothing more than a single shot 20 guage.  So, legally you're fine.  In reality, if they want to screw you, you're screwed.

Let me clarify my reference to the dummy M-16.  That is a M-16, with all its parts except the lower receiver, which has been replaced by a dummy non-functional receiver, to be used for display purposes.  

I bring this up because I've heard that it is not a good idea to have military dummy machineguns and also possess their civilian semi-auto,counterpart.  (eg. possessing both the Thompson SMG dummy gun and also the the new production semi-auto Thompson made by Kahr.)

Is it me, or are these laws kind of confusing?  
Thanks guys for your insightful wisdom.
