40+ years of GI M16 mags detailed in about 17 minutes
Black rifle expert Chris Bartocci convenes class on the evolutionary process of GI 30-round M16 magazines from Vietnam to today.
Going back to the old black-follower mags and moving through the new blue-follower EP mag, touching on everything in between, Bartocci breaks down the reason for changes to the feed lip angles and the body itself, and points at the ammunition-based reasons for each.
It’s a scholarly look and you don’t get any wackiness or Tannerite explosions in the 17-minute clip, but if you are curious about the what, when and why there are so many GI mags and followers out there, this is worth your time.
