A couple of weeks ago I was handed this mauser for free. 7X57 cal. Since I already have a couple builds in progress I thought I would do this as easy as possible. Since the bore looks good and it's in the caliber I wanted I figured I would use the existing barrel. 1st I removed all the black epoxy and the old military sights. Then I cleaned up the original stock, which I believe is walnut, installed a pachmeyer recoil pad that I already had. Then I cut off the old bolt handle, heated and hammered it back straight, put a swept back bend on it and rewelded it. I welded it low so that I can go with a small 4X scope mounted real low. So far, no money invested. Next, drill and tap for a scope, offset safety, either redo or install a new trigger, and shorten and re-crown the barrel. Here is a few pics.
