||Ok, to begin, with since no one else has said it yet, this grenade shell can take co2 no sweat. i've had mine for about 7 months, 3 of which it was dissable since I lost a ball bearing. My friends would rather surrender than to be shot with this thing. with co2, as you may have guessed by now, it tends to have some kick. Though if you do use co2, it's a good idea to keep it lubed. If you use green gas then your gold since green gas has silicon in it already. Durrible enough to be dropped a few times plus some. Only scratches the pretty paint, which i can live without. 204 bbs can cover quite an area, though I mostly use it for bunker sweeping and such. Also note: very loud. so whatever you're going after you'd best hit it or be ready to book it cuz they will know exactly where you are.
Over all, great shell. Nice job Mad Bull.

Covers large area
Great bunker sweeper
