A combination including a paint ball gun with a gun barrel has both a muzzle portion and at least two interchangeable compression zone portions of slightly differing diameters. The compression zone portions are preferably attachable and deattachable from the muzzle portion by a non-threaded connection mechanism, such as by a snap-on type connection mechanism, a cam-lock type connection mechanism or a bayonet connection mechanism. The invention allows the user of a paint ball gun to select a compression zone portion which is most optimally matched to the diameter of the paint ball ammunition to be used in the paint ball gun. The invention thereby optimizes paint ball gun performance. |
