Questions & Answers
Anyone successfully using these with 9mm PSA (with Hybrid bolt) upper? Expert Answer

what bcg's will this work with? haven't found one yet. Expert Answer

It should work with any standard 9mm bolt carrier group. Please email us at techsales@opticsplanet.com with 9mm bolt carrier groups you have attempted to use with these magazines as Mean Arms specifically states:

"The new 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"
