The STAR/GREEN LABEL PMAGs cannot be taken apart. They do not have the locking pin on the top about 1 cm under the feeding lip, only the 120rd ones do.
Anyways, the STAR/GREEN LABEL's body is held on together by internal pins, or worse if it's internal pins and glue.
The part of your feeding lip that holds the BB's together, or I shall call it a
BB Catch can be replaced by any M4 kind. That's how it is on my 120rd PMAG.
What I think you could do, is grab a flat head screw driver, and try to open up the feeding lip and then pop it out in place. If not, bust open the PMAG with full force, and then use crazy glue to put it back in place.
If you bought those STAR/GREEN LABEL box set, then you saved some couple of dollars. Buy another single STAR/GREEN LABEL PMAG from VelocityArms.
