Yep! The nib/feed section is friction fit. So grab hold (minding the nib; using pliers if you care to, but with something to cushion it as to not mess up the nib), take yourself over to the sink, and give it a good twist/pull. It should come out with a satisfying "PLOOP!" haha and spill ink into the sink. Might not want to wear your best Sunday shirt either. I've not had an ink massacre, but because it's friction fit, you never know. After that, use an eyedropper or syringe and fill up that barrel!
