Used to knock out bore obstructions. These attach to the end of the Memory-Flex cable, can be used to clear the bore of mud, snow, dirt, or stuck cases. The end of the obstruction remover is concave so it does not hit the firing pin when trying to remove a stuck bullet. This also prevents the stuck round from mushrooming within the barrel. The obstruction remover also acts as a T-handle base. For .22-.27cal firearms use the small obstruction remover. For .30-.50cal firearms use the large obstruction remover.
