The problem is when i try to load in the stanag 30 round magazines through the action menu, instead of being loaded into the gun, the dual purpose magazine will stay in and the 30rnd will be deleted from my inventory. The only way i am able to load it successfully is by opening the menu, dragging out the dual purpose magazine and then dragging in the 30rnd.

A secondary issue I've been having is with the effective range of the dual purpose magazines on land, which seems to be limited to something like 5 meters. I have shot multiple times on multiple occasions at npcs that are no more than 15 meters in front of me and the bullets seem to not even hit them.
