The MEAN EndoMag serves as a magazine insert designed to transform your Gen 2 or Gen 3 5.56/.223 PMAG housing into a 9mm magazine. This conversion allows compatibility with a standard AR lower and a 9mm upper of your choice, utilizing either a Glock or Colt variant 9mm bolt carrier group (BCG). We provide two versions - one equipped with an ejector for standard blowback bolts and another ejectorless version compatible with our Bearing Delay and CMMG radial delay systems.
