I recently got an aftermath m9 co2 gbb, only to find out one of the mags i received was missing the sealant for the 12 gram co2(the o-ring around the puncture needle).
its basically this, i had to use my friends nbb magazine because my magazines are extended and the sealants on mine are clear. It would have been very hard to take a picture of it.
