The BSA Fill Probe Spitfire/Firebird allows filling from a standard fill line rather than from a buddy bottle for the Spitfire/Firebird models.

You will need to screw this adaptor into the port where the Buddy Bottle would normally attach, and then connect on your fill line via the screw nut. After filling, reverse the above procedure after venting the fill line.

We suggest using this adaptor with one of our quick coupler kits so that you are able to fit the adaptor to the rifle, and then connect and disconnect the fill line without using spanners, making the filling process much quicker and easier.
