Here is my father's Christmas present for his Argentina Mauser. I bought an S&K scope mount that replaces the rear ladder sight. I was planning to get a long eye relief scout scope for on it but remembered I had a Sightron red dot waiting for a home. I do not think he has shot it yet but he is excited to shoot and hunt with that rifle again. I got him some Prvi and Hornady ammo to try along with the Norma he always used in it.
Here are instructions that came with the scope mount. It was pretty simple to do.
