Re: How do you remove a dovetailed rear sight?
Make sure you MEASURE each side of the sight base before you drift some are ONE WAY ONLY.. Also make sure you have looked to be sure there is not a set screw holding it and if so remove that first. Make sure if using a punch it is BRASS if your keeping the site to use again I recommend a layer or two of masking or electric tape to keep the metal transfer down to a min. If you can not drift it without a sledge lube it let it soak then try again.
Also it is ALWAYS a good idea to cover the are surrounding the dovetail with a few layers of masking tape while removing and installing the sight just in case you slip with the punch or hammer.
