Butlerstranger & reincarnated:  Thank you for the great information. I will look for a screw in peep. Reincarnated, you bring up a great point,  I think I will leave this gun the way it is. My grandpa was a "woods hunter" and lived in northern Wisconsin. After talking with my uncle, it sounds like grandpa  had 7 Krags.  What parts should I gather to try to make sure it will fire for years to come?  I plan on taking it to a gunsmith for a checkup before using it.    Thanks again, Jason
