Military issue WW2 rifle bore cleaner. This bore cleaner come in 6 oz. cans, so there is plenty to clean many rifle bores. The cans are military surplus from world war 2, and many people buy this just for the can itself. However, the cleaner is still viscous and will get the job done. The cans are old and have have some rust and pitting, therefore the labels are not perfect. Also some of it has evaporated over the years, so we will always send out the heaviest cans.
