umm barrel sizes .686, .688, .690?

[arf.]

i can only buy one size right now and i dont really know which one to get wat are the diff sizes for?

[VeNoM]

they make different size paintballs (small, med, large etc...) and you want to be able to match your paint to fit the inside of your barrel for best accuracy. do you know what kind of paint you usually use? i would get a .689 barrel (med. bore)

In my opinion, .688 is the perfect boar size

I'd go with the .688, .689 if it's available.
