I tried to make a cerrosafe cast of the chamber of my M96 got too much in it and then couldn't get the cast out! I heated it up with a hair dryer and got most of i out but not all of it. https://www.milsurps.com/images/impo...16ea5d92-1.jpgWhat I think I want to do is submerge it in boiling water but I don't think I want to submerge the bolt stop at the same time. Question is (and you're welcome to tell me a better way of getting the remaining cerrosafe out) how do I remove the bolt stop?
