I went ahead and ordered a cherry
vape tip. If my delrin ever melts out, God forbid, I'll post back and tell you all if the little boy chuff tip fits in there. I can't for the life of me pop that insulator out of the top cap without ruining it. However, I did figure out that it is wider on the top than it is the bottom, so I am kind of doubting that the LB tip would fit in there. Then again, we won't know until we try.
I think this tip will look pretty wicked with the delrin already in the top cap.
