For those who have upgraded to the Paradigm Pro, but want to reuse your old K-Series magazines this is the part that you want. The square head collar will fit on any MILSIG K-Series 20 round magazine and convert it to be usable on the Paradigm Pro.
Installation will take approximately 5 minutes and involves just taking apart the body, removing the old head, and adding the new head.
