I made some new adapters for the current 120psi CO2 regulator. The old co2 regulator from several years ago was around $180 and required a $38 adapter for the 20oz paintball bottles and a little $8 adapter for the 16 vgram threaded cartridge. The new (from several years ago) 120psi CO2 regulator $83 is integrated to work directly on the 20 oz bottles. Unfortunately then we didn't have a way to use the small 16gram cartridges on it. Anyway I finished some adapters that have a probe in them so we can use the small 16 gram cartridges again that need to be pierced.
These are 16 gram cartridges that we used to use as kids in our pellet guns. I updated the site with this adapter.
