Zombie Zapper Battery Compartment Cover
Also know as “Butt Caps”
We realize that not everyone can hold onto their Butt Caps, or sometimes you just bust your Butt Cap (which I know is painful). So we’ll ship you two of these things.
We’ve upgraded our Butt Caps to a solid resin, which fits into the ends with a much tighter fit and can take a lot more punishment.
You can also 3-D print your own if you prefer, the model can be found at https://www.thingiverse.com/thing:4005219
