Loved the Silver Bullet. It's a shame they are no longer being manufactured.
I do hope you are aware that the Dreamer is a hybrid top, or direct battery mod, and are aware of all that entails from a safety perspective. There is no 510 center pin.
The only type of atomizer that can be used on a direct battery mod is one which has an
extended center pin in the 510 connector. Using a normal 510 connector without an extended pin will result in shorting out the battery which can lead to a battery venting or exploding.
Additionally, I could see
no vent holes in the Dreamer. There are some fake holes within the fire button, but they would not allow venting of gas should a battery vent; the holes present are merely there to guide the fire button.
At first glance, there appears to be some vent holes on the outer edge of the fire switch. However, they are not vent holes at all, they are there only to help guide the switch slide down to make contact with the battery.
So, if a battery should vent, this mod is an enclosed metal tube with the gas having nowhere to go. It would essentually be a pipe bomb.
Be safe, my friend.
