QUESTIONS
1) Can I remove the ejector trigger hook and turn this gun into an extractor. The 25-20 cases are so hard to come by that I don't want them shooting over my shoulder to be lost in the grass. Yes, see above comment.
2) Does anyone still make stocks for these guns? Yes, but again search the internet, Boyd's makes a stock, but I have found it to be a little small over all. Others are available on the internet.
3) Would it be a crime to refinish the metal work with a rust blue? No, due to the poor condition of the metal now.
4) If I wanted to install a peep sight on the top of the barrel, what have others found worked? Am I correct in assuming you mean a peep on the rear standard sight? I have seem them on lots of rifles, but have no personal experience. Or do you mean something like a Lyman or William frame mounted peep sight? Both companies make one or more for this 219 Savage.
