Hello
I have been playing paintball for fun for a couple of years now but now I have decided to take it abit more seriously. Today I purchased a BT-4 Assault paintball gun.
http://www.btpaintball.com/f_bt4assault.php. So now I have the equiptment I need I should be set up for now

I was wondering about these grenade launchers I see for sale. Why do you charge the grenades with Co2 and does it just fit onto the gun also would any fit my gun? Sorry for all the questions just need to find out more. Also any help or tips would be much appriciated.
Thanks,
Kieran
