I have 2 Mauser action rifles. Both 7x57mm.
One is a modern (1980's era) European made "Mark X" hunting rifle and is slick as glass & has beautiful walnut wood. Excellent adjustable trigger. Comes drilled & tapped for scope from factory & if memory serves has iron sights as well.
The other is a 1908 Brazilian contract military rifle made in Germany between 1908-1914 (I think) and sold to Brazil. In the late 1950's/early 60's Brazil sold some to the Dominican Republic and these were D.R. arsenal factory refurbished. Mine is in a sporter configuration and is stamped "1961 Rep Dom" and is ABSOLUTELY beautiful, almost mint condition, with beautiful dark walnut. Being military, it has a much longer throat than the commercial variant Mauser.
In my opinion, if you want a Mauser, get one. People bitch about modifying military rifles, and I agree with the above. Get one already built, cuz it can be a rabbit hole/money pit if you wanna start with a military surplus action & build up.
