This tube mod honestly has a ton of potential, but unfortunately misfires more often than not. With a proper battery wrap, it will fire pretty regularly. Unfortunately, I just don’t have a lot of those wraps that work at the moment. I was mostly joking about the 24 mm vs 22mm for MTL. I personally would like to see more 18650 22mm MTL stuff available.
I’m actually surprised that CTHULHU MODS didn’t just make that white delrin ring adjustable or spring-loaded. Such a shame on an otherwise really really nice feeling mod. There is a full-mech option for this which does work fine, but again… unless the pin is hitting the battery, it doesn’t much matter what you put on top. Don’t get me wrong, The Cthulhu Tube Mod II is safe and does have a safety mosfet built in. Like I said this is a great idea. Bad execution.
