Custom Product paintball barrels are affordable and accurate.  This barrel is .685 inner diameter.  This is the standard I.D. of paintballs.  This may be slightly smaller than a stock paintball barrel.  The exact matching of the barrel I.D. makes your paintball shot more accurate.
This barrel will work on all Tippmann 98’s, Empire BT4’s, and all US Army Paintball guns.  When using an aftermarket paintball barrel on the US Army paintball guns, you will need to shim outside of the barrel thicker so that it will create a snug fit with the stock front shroud.

All CP products come with a lifetime warranty from Custom Products.
