From only a small sampling circle of acquaintances, I'm personally aware of over a dozen ARs purchased in Maryland within the last couple of weeks that would have been many months out otherwise, if ever purchased at all. Seems to be some gambling on the likelihood of a grandfathering-amended version of this going through, or some definite willingness to Not Comply after Oct 1, on purchases made while the getting is possible at all. Don't know if it amounts to outright panic buying, but it's not just some seasonal bump, either.
