It should be, using one of the following methods.
1. Use a screw driver in the 510 connection.
2. Remove the top cap and use your fingers to screw the pin in or out, attach the atty as you want it, tighten the center pin, then put the cap back on the mod.
You should set up your center pin before putting in the battery and tightening things up, otherwise there might not be room for the pin to turn/move in your desired direction. Once the center pin is adjusted...then tighten the button end.
The switch throw pin can also be adjusted by turning with your fingers.
