This is mine;
When I was in college, I was in ROTC, and we would go on exercises with actual M16's with blank ammo.They would give us 20 round mags to use, but some of us went out and bought 30 round mags of our own so we could have more fire power. I went to a military surplus store and got a descent steel 30 round magazine for something around $5 back in 1980.
Sadly, when I came home from leave from Germany in the mid 80's, the magazine had disappeared.
