Hey guys. I recently picked up a sportshot, and while my primo fit just fine in my Nightkast Pump's feedneck, I can easily shake the sportshot out. I'm looking into nabbing a clamping feedneck, and I'm just curious if the current one comes off? Just looking at it, it looks like it could be a part of the body, but I'm not sure. Could anyone help me out here? Thanks, and pics can be provided if needed

EDIT: I tried to electric tape the hopper, but it made it too thick. If theres any cheap mods I can do then that would probably be best!
