Load in your 12 grams. Screw it in to the ASA. Use the 12gram, then pull back the lever to change it out.
I would use some expended 12vies first, to make sure they are loading properly before airing it up.
I recently managed to pick up a 6Pak, and now it's in my hands, I realize I have no idea how they work. Can anyone enlighten me?
