It really seems the surplus GI mags dried up pretty quickly. I thought we would see them flood the market when the military started using PMAGs, but they may have had DRMO collect and destroy a lot of them (I’ve been away from the line for a while now). I used to see boxes and boxes of them at shows, and when I lived in El Paso about 6 years ago, a local surplus store was selling them at 6 / $30. I honestly think $5 is a fair price for used surplus mags, based on the condition most of them are in, but they’re getting scarce. Lately at shows, I only see a few here and there, and people are asking $15-$20 for well-used mags. Quite often they’re Center Industries mags, the least desirable brand, since people have long since picked out the Okay / Colt mags.
