I just purchased this fitting and was wondering do I put it on the tank and then screw into gun or put adapter in gun then screw in PB tank? Also do I need the brass adapter as well you sell. Thanks in advance.

It is easier if you screw it into the gun first and then screw on the tank. You should not need a brass adapter as long as this is going on a Hammerli 850.

does this also work for HPA? I believe that’s a different tank.
