This adaptor allows you to choose either to use the front or just the back air bottle when you use the FX Panthera front bottle adaptor. It will make the panthera super easy to convert on the fly between bench, hunting and prs.

The adaptor is made of aluminum and completed with a stainless steel foster male quick connect adapter. This foster male adapter has an o-ring powered check valve. It allows you to connect your rifle directly to your air cylinder or scuba tank if you want to shoot tethered or if you want to test and setup you rifle and you don't want to spoil any air by screwing your FX bottle on and off the rifle after every adjustment you made.
