Just when you thought it couldn’t be any more confusing. Here is the way I read this horribly written “clarification.” The above is actually a list of items designed for firearms and that attach to firearms, but ARE NOT “Assault Weapons Attachments.” From PICA:
“(3) "Assault weapon attachment" means any device capable of being attached to a firearm that is specifically designed for making or converting a firearm into any of the firearms listed in paragraph (1) of this subsection (a).”
None of the items on list from the answer make an firearm an “assault weapon.” For example look at “Aftermarket stocks that do not otherwise meet the criteria in (1)(a).” From above. I think the ISP are trying to say that if a stock is not:
“(iii) a folding, telescoping, thumbhole, or detachable stock, or a stock that is otherwise foldable or adjustable in a manner that operates to reduce the length, size, or any other dimension, or otherwise enhances the concealability of, the weapon;“
Then the stock IS NOT considered an “Assault Weapons Attachment” (ie a fixed stock that would go on an 20” AR15 Colt Sporter would not be an “AWA” because that is not a feature making that firearm an “AW”). Unfortunately, because of the way it’s worded, it is impossible to know fore sure.
