1000 rounds non-corrosive/non-magnetic, asking $650 for the whole case.
Inside are five 200 round battlepacks, judging by an older posting on NorthwestFirearms that features a case of the same Pindad MU-2TJ.
I'm in the Everett area, and I shall be at the Washington state/Monroe Fairgrounds gun show on January 31st/February 1st as well. Thanks!
