different launchers are made for different shells so the firing pin isn't always going to be long enough.

if memory serves, the KA valves require a longer firing pin than a madbull. (needs to be pushed in further)

you could make some metal slugs about 5mm and glue/jbweld it to the back of the valve. would be more consistent than a wad of tape.
