AXMC 2 round holder

Hoptic is the only one I’m aware of. I have a couple and they’re nice but I don’t use them because at 5’ 5” I’m not a full size human and can’t easily reach it in most positions. I run the SAP placed on the magwell below the port and it works well. I’ve even stuffed 300WM rounds in it and surprisingly it didn’t stretch it out.
