You' re going to get widely divergent advice on this.....hold on...

Yes, quality deteriorated rapidly at the end of WWII...most of it you can see visually.....they used stamped trigger guards and floorplates...they deleted the safety locking lug at the rear of the bolt, and they reduced quality control in other areas....however if yours has a regular floorplate, and has the third locking lug on the rear of the bolt, it probably is not seriously flawed.

Here' s the wrinkle.....if you want to install a scope, you' ll also (probably) have to install a new bolt handle and a new safety....

The old ones will not work with the scope.

If you do this, yopu have started down a long road to an expensive sporter. Next a new trigger, next a composite stock, next a new barrel.....and bluing....in the end you could have bought a new Winchester, Remington, or whatever.....

I recommend that you take that mauser to the gun shop and trade it for a gun you like.....you' ll be money ahead.....and you' ll have a caliber that' s fitting to your needs.

Don' t get me wrong......a converted mauser properly done is a magnificient piece.....but it' s expensive unless you can do all the work.
