I know that over the years the military has deemed several brands of magazines to be "defective" for one reason or another and taken them out of service. Does anyone have a list of the ones to be avoided? With the influx of cheap mags I want to stock up(while we still can :?: ) but don't want to get out of spec stuff. I know to avoid most non-USGI like the black plauge but am concerned about the USGI ones. Thanks in advance. T.J. Robertson
