The BATFE hit polymer80 (and other retailers) with subpoenas for customer data on who bought build-a-kits for pistols. If I recall, all of the subpoenas were ignored.
It depends on the level of cooperation on the retailer, the severity of the item, and the quantity sold. Something that only has a few hundred sales would be easier to track down and confiscate than something that sold millions of units. A small mom & pop retailer might fold under a subpoena but a larger retailer would have resources to litigate it.
