Barrel Bore Size Chart

I have tried to compile the many barrels that are available here.  Some barrels that are listed are no longer made, but are still floating around out there on ebay or private sale.

If you already have a barrel and want to find out what paint matches that barrel the best, simply look at the list below for the barrel that you have. Find it’s bore description. Look at the paint chart. Look at the size description of the paints. Matching descriptions means a matched paint to bore. You do not need to be exact since paint is not exact. Go by small, medium, or large designations for matching paint.

But the best way to match the paint to the barrel is a simple test called the blow test. Since paintballs are not always round, made the same, weather, or how old they are, place the paintball inside the barrel. If the paint rolls out of the barrel, the paint is too small. If you just about pass out trying to blow the paintball out of the barrel, the paint is too big. If you can blow the paintball out with moderate ease, then it is a match.

If you want more detailed information about barrels, read through my Barrels – F.A.Q. for lot’s of info.

If you do not see your stock barrel listed below, you can pretty much assume that it is considered as a medium bore barrel.

The bore sizes are based on the following sizes listed on the chart below. I have personally measured most of the barrels listed. Others that I have not been able to measure, I have contacted the maker to get the bore size. Many thanks to those manufacturers for this valuable information.
