Cock gun before removing locks. Having spent some time and trouble on the innards of a used 12 ga., I can say that I had no difficulty removing the locks without damage to stock wood but that is a risk. In fact pushing with the cranked screw after backing out a few turns popped the r/h lock and I pushed the left out with a pencil. Some here have suggested light taps on the front of the action bar is the "recommended" way. Don't force; don't pry; pop them over covered bench top, carpeting, sofa, not over a concrete floor. Curiosity may not be the best motive for removal but we've all been there. If you have questions when it comes time to replace, don't hesitate to ask. Finish is a "not enuf oil" finish.
