1. A modular disruption system for explosive ordnance disposal, the modular disruption system comprising:
a first barrel section having a first end and a second end and having first barrel characteristics and first barrel dimensions;
a second barrel section having a first end and a second end, the first barrel section and the second barrel section being configured to guide a disruption projectile from the first end of each barrel section to the second end of each barrel section, the second barrel section having second barrel characteristics and second barrel dimensions, at least one of the second barrel characteristics being different from a corresponding one of the first barrel characteristics;
a first chamber section having a first end and a second end, the first chamber section having a first chamber caliber with a first chamber throat geometry to transition the first chamber caliber to the first barrel dimensions of the first barrel section, the second end of the first chamber section being detachably attachable to the first end of the first barrel section;
a second chamber section having a first end and a second end, the second chamber section having second chamber caliber that is different from the first chamber caliber with a second chamber throat geometry that is different from the first chamber throat geometry to transition the second chamber caliber to the first barrel dimensions of the first barrel section, the second end of the second chamber section being detachably attachable to the first end of the second barrel section; and
a breech portion detachably attachable to the first end of the first chamber section and the first end of the second chamber section, the breech portion being configured to initiate firing of the disruption projectile.
