How do you lock down the bulk fill fitting so that the 45 angle is clocked right? Mine bottoms out before the port is positioned right.

are these drilled for extra screws to hold in place for hpa?

No, and this is for Crosman. If you want One for Discovery (hpa) you’ll need the Max-Flow for Discovery.
