You're missing the point. (I think?)
Their property was taken, with a warrant. No charges were filed, no explanation given. Now, BATFE is listing the property to initiate forfeiture proceedings... again, no charges, no explanation. Cav Arms must now petition in order to regain possession of their property. That will cost a great deal of money. And they likely don't have much money, since BATFE essentially put them out of business by confiscating everything.
In other words, their property, and indeed their livelihood, has been taken, with no explanation, no criminal or civil judgment -- not even a hearing. They will lose -- no, they have already lost -- their property, and won't get it back unless they can make a successful argument in court.
What ever happened to the presumption of innocence? This is not due process, it is simple highway robbery. Surely their entire inventory is not being held as evidence, especially as BATFE is looking to dispose of it. I can understand property being seized with a warrant and held as evidence. On the other hand, civil forfeiture without preceding substantive due process or a trial judgment is... well, the only word that comes to mind at the moment is tyrrany. (Oh, and IMO, substantive due process would require a chance for both sides to be heard.)
