The obstruction removers are used to knock out bore obstructions. These attach to the end of the Memory-Flex® cable, and can be used to clear the bore of mud, snow, dirt, or stuck cases. The end of the obstruction remover is concave so to 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 alsoacts as a T-handle base. On the end that is concave, there is a hole for the tapered T-handle bar to slide into.
