Refinishing can’t hurt the gun as long as you separate the metal and the wood. If you have doubts about your ability to do this, have a gunsmith do it. I recommend Birchwood Casey Tru-Oil. It has been around fo ryears, is simple to use , and gives excellent results.

I have an old Stevens side-by-side whose stock has taken a beating over the years, and I'd like to refinish it. Will refinishing harm the gun, and can you recommend a good sealer for the wood?
