The reason the AK magazines were so cheap during the ban was because despite the ban AK nagazines were still being imported so the supply was not disrupted the reason being because the ban only said that magazines made after 1994 were banned it did not ban forien made magazines, so as long as it was maid prior to the ban any forien magazine could be imported, and because they made so many of them in the first place there were plenty of pre ban AK-magazines and those kept being imported, and that included drums, so as it applies to AK magazines the price should stay the same.... As for the drums they could have been imported all along so the reason they stopped importing them is for some other reason then the ban, my guess would be that there were less RPK's built then AK's (The drum magazines and the standard magazines that hold more than 30 rounds were actually desighned for the RPK....) so hence not as many drums as magazines, and the remaining drums are still in use by there respective millitarys.... So they sold us there spares and that was it.... Now we could still import more drums but unless they release more they will have to be new manufacture ones which could be why no more were imported during the ban, so there may be more soon but if there newly built it probably won't affect price much....
