I have 2 pieces of gear that are part of my EDC my R6 rucksack and a pouch from Fabric Horse. I wanted to mount the pouch to the R6 so I made this adapter. You feed any thin 1" nylon webbing through the H portion on the back of the adapter, the other side mounts to the Arkiv rail on the R6. This method of mounting the webbing is convenient since the webbing and buckle do not need to be sewn in place, you just place the buckle on the pre-sewn webbing loop. The buckles are fully removable.
