Mean Endomag 9mm 3-Pack

The MEAN EndoMag is a magazine insert that converts your Gen 2 or Gen 3 5.56/.223 PMAG housing into a 9mm magazine to use with a standard AR lower and 9mm upper of your choosing with a Glock or Colt variant 9mm BCG.

We offer both a version with an ejector (for standard blowback bolts) and an ejectorless version (for our Bearing Delay and CMMG Radial Delay systems).

Specifications:

• No modifications to your 5.56x45 lower receiver. Changing calibers is now simply a complete 9mm upper for your AR platform. No nuts, no bolts, no drilling, no bull.
• Last round bolt-hold open feature, just as an AR-15 should function.
• Built-in ejector designed to perform under intense conditions.
• Convert your 5.56x45 PMAG to 9mm in seconds, and easily convert back to 5.56 without damaging your PMAG. No permanent changes to anything!
• Specially formulated polymer.
