Series of noob questions...in a paintcheck the ref comes to you right? CO2 left in the tank for a long period of time is bad right? What can you use as a CO2 source? What is the the best cheap paintballs that work with the A-5? Whats polished internals? How much does an A-5 bolt increase range and accuracy? ...Thats it...

yes the ref comes to you but however if you get shot while the ref is on his way to tend to you then your are out.if you leave Co2 in the tank for to long i think the only think that could go wrong is it will leak out.your cheap paintball question has to do with you barrel,polished in ternals if exactly what it sounds like try using the serch button found in the to right corner between the "memberlist" and "help" buttons.your bolt question-i have herd that the best bolt for your a-5 is your stock bolt.the superfly bolt was shist...or i thought so...

in a paintcheck the ref comes to you right?
The ref will come to you, if he is checking you during a game usually you just keep playing normally while he is checking you.

CO2 left in the tank for a long period of time is bad right?
No it won't hurt anything, but it is not a good idea to leave the co2 screwed into your gun for a long period of time (I'm talking days, don't worry about leaving it the whole time your playing)

What can you use as a CO2 source?
Do you mean where can you get your tank filled? A local field should be able to fill it for you, if you don't have a local field ask the people you play with where they get theirs filled and just go there.

What is the the best cheap paintballs that work with the A-5?
Try these paints, anything made by Draxxus, PMI Premium, Xball Bronze, Nelson Hotspot (not as good as the others but I use it sometimes), and if you have to buy from wal mart(which you should do everything you can do avoid) get gameface scortch.
If you have a local field the majority of them require you to use their paint so check with them before you buy paint first.

Whats polished internals?
Exactly what it sounds like, some people polish the internals of their tippmanns since stock they are pretty  rough, it will decrease the wear on your bolt and help your effeciency a bit too.

How much does an A-5 bolt increase range and accuracy?
I'm not really sure what you mean by this, could you try explaining this question better?
