Hey guys! Does anyone know if the mutation x v1 top cap will fit the v2? I currently have the v2 and it doesnt fit any 510 drip tips. I know i can attach any 510 drip tip to the one that it came with but it is ugly!! So im wondering if i could find & buy a v1 top cap to put on my v2 so i can use my 510 drip tips.
