Im gonna make a cynical guess, that this postponement has nothing to do with civilian firearms, and everything to do with military firearms/weapons (i.e. LAVIII to Saudi Arabia) that are being exported for sale. The manufactures are either not set-up, or not able to, or for political reasons, don't want to, adhere with sections of the act, prior to completing deals that are in progress. I have no facts to back up this assertion.
