After shooting today, I cleaned my rifle and ran an oil patch down it. I can't get it out. Stuck about a foot down. I need to know about a Kentucky Rifle made for Sears, Roebuck and Co. by Miroku in Japan. Is the block screwed into the barrel and, if so, is it threaded with right or left threads? I tried so hard I separated the cleaning jag from the rod. Pulled the rod right out of it.
