A well-trained user knows how to deal with any of the plethora of malfunctions an AR-pattern system can serve-up on a whim.
A significant number of those malfunctions start with the magazine...
For training purposes, what would you do to an otherwise good magazine to create a 'MalfMag'...a magazine specifically intended to cause a feedway stoppage in an AR-pattern weapon?
If you recommend a modification...(e.g., "bend the feed lips downward")...please describe what malfunction you expect the modification to induce...(e.g., "will cause either a bolt-over-ride, or a round will brace against the feed ramps and keep the bolt from closing")
