CTHULHU AIO Replacement Firing Button
The Cthulhu AIO Replacement Firing Button is an optional button for customizing your Cthulhu AIO. There are three options of buttons, and each one is sold individually. The Black Delrin 'Eye of Cthulhu' Button features a dome shape that protrudes from the outer panel of the mod. The Naval Brass Button features a concave design. The White Delrin Button features a flat design like the stock button.
Warning: Replacing the Firing Button requires the inner panel of the Cthulhu Mod to be removed, exposing the wiring and chipset of the device. Remove battery before unscrewing the inner panel. Mod at your own risk.
