Wow, what a collection, I'm jealous thats at least a good 4k in nades alone. I only got 3 nades :/

I use co2 as well for my Madbull shell in my Echo1 m203, works fine however I would warn you that round might fire off on its own when loading the nade, make sure you dont slam it, or just dont over load the nade with too much co2 and you'll be fine.
