So in my haste to get an order in before going to bed, I just ordered from madvapes.com a couple of new cartomizers for my 510 Puck mod... and upon looking at my confirmation email, I realize I clicked and ordered the Ego cartos rather than the 510 cartos 
Now from what I have read, 510 cartos will screw onto Ego batteries, just without that neat pretty ring around the connector. Would it be possible, perhaps through the use of a Dremel or something, to chop off the ring from the Ego cartos to make them work with a standard 510 connector?
