If you’re a veteran CO2 user, the title of this report will confuse you, because bulk-filling and CO2 cartridges are two different ways of charging a CO2 gun. But, today, I’ll show you a device that lets you use a CO2 cartridge to bulk-fill a gun. And there’s a lot more to this story than just that!
Over two years ago, my good friend Mac traded or sold me a .22-caliber Crosman model 114 CO2 rifle — we can’t remember which. The rifle was in nice shape except that it didn’t hold gas, which is the kiss of death for a CO2 gun. No problem for me. I sent it off to Rick Willnecker in Pennsylvania to be resealed.
