Here is a pic that Zonie posted back in 2006. The lock on my latest T/C Renegade .54 cal rifle has been cleaned, by a previous owner, to white metal, as has the barrel. I am going to rebrown the barrel but I need to do something with the lock. Zonie said that he got the results shown by heating portions of the lock with a pencil type torch. If I attempt to do the same do I need to disassemble the lock first? Can anyone give me more tips or advice before I try it? I appreciate any help offered.
