The MEAN ExoMag is engineered to be a reliable, smooth-feeding 9mm magazine while maintaining the familiar STANAG outer profile. Pair it with the 9mm upper of your choice (Glock- or Colt-pattern 9mm BCG) to run 9mm on a standard AR-15 lower—no magwell adapter required. All ExoMag models include a last-round bolt hold-open, just as an AR-15 should.
Capacity: Standard 20 rounds (9×19mm)
