I heard there was a grenade launcher for pball? Is this true if so can I use it at any field and how exactly does that work?

while there are a few different types of rocket launchers, many are not acceptable on commercial fields.

When choosing a rocket/grenade launcher, you need to know two things.
1. does it have a way to regulate down to 300 FPS?
2. does it shoot only paintballs (some shoot nerf rockets, etc. just make sure you have all the equip to shoot paintballs)

as long as you meet those criteria, you shouldn't have much of a problem shooting it at any commercial field.

Hi,
From where do I upgrade the latest gagest like rocket launcher, boobs, etc. for the paintball.

I have also heard about that but i am not pretty much sure about that...
