The rippled ss tank is a beauty. reg size fits the boge carts nicely. well the carts are actually a tiny bit bigger than the tank. only prob is they are REALLY slidey on the carto. if you get the matching tip it wont let the tank slide off your carto. so far no leaks. did I mention they look SHARP! View attachment 89257 If you look closely you can see that the tank is resting on the top of the mod and you have to adjust slightly not to block airflow. but you still have a little bit of carto at the top(after adjusting) maybe after a few slidey reviews they will fix the o-rings.
