mad bull xm203 and mad bull shells

[Fox Hound]

I'm really interested in an m203. But i'm using the Scar grip/bipod on my M4 so i can't fit the standard m203 on my rails. So i was thinking of getting a Mad bull xm203 shorty and placing it in front of my scar grip/bipod.

I've read some reviews but a lot are from sites that sell them, kind of bias i think. Anyone own one?

Can all shells take C02, i think that would be best because i have c02 tanks at work.

Anyone know where i can read up on reviews for shells. They're pretty damn expensive to do a trial and error buy.

If you want the most powerful shells around, get them. CO2 lets you use them all winter long with great standing range. The needed regulator lets you dial them down from field games to CQB. A large investment, but for the serious player, well worth it.
