Given the dates of manufacture, some HK11 LMG and G8 'sniper rifle' drum magazines could have been imported to the US long before the high-capacity feeding device ban went into effect. The original HK11 had an optional 80rd saddle drum, and the HK11E and G8 have both been offered with a 50rd drum. The drum magazine shown in certain MSG90A1 (DMR) photos is the same offered for the HK11E and G8.
How many were imported pre-ban (if any) and where to find them is not known to me.
