I recently snapped off the factory barrel tang sight on my 1895g and I'm looking to replace and upgrade too a rear receiver mounted peep sight. I've run into a problem that very few are offered specifically for the guide gun. My susspession is that the 1895 and 336 all use the same receiver hole spacing and the sight manufactures haven't bothered to update the application page for their sights. I mostly use 1 load for this rifle so quick adjusment isn't necessary for me. I really do like the Williams on my other rifles but I don't feel the need to go that route on this one since it's a field gun and is prone to be being banged and dropped around. Anyone have experience with this rifle and mod?
