I bought a .45 Jukar Kentucky Rifle from gunbroker.com on the cheap and need to clean it up. Barrel looks almost unfired, and it was used as a wallhanger by the guy who I bought it from. It was obviously a kit gun and put together rather sloppily. My question is can anything be done with a poorly inletted lock seen below? Any way to fill the gaps? This doesn't even look like it was the correct lock for the kit. I've got some cleaning ahead of me. Will use brass cleaner on the brass. Any good products to clean the stock with? Murphy's Oil Soap? Thanks for any help or general advise.
